South Carolina does not use a fixed alimony formula. Family courts calculate spousal support by weighing 13 statutory factors under S.C. Code § 20-3-130, including marriage length, income disparity, standard of living, and marital misconduct. A South Carolina alimony calculator can help you estimate a reasonable range, but every award ultimately depends on judicial discretion. The filing fee for divorce in South Carolina is $150, the residency requirement is 1 year (or 3 months if both spouses reside in the state), and no-fault divorces require 1 year of continuous separation before filing.

How Does a South Carolina Alimony Calculator Work?
A South Carolina alimony calculator estimates spousal support by analyzing the income gap between spouses, the length of the marriage, and each party's financial needs against the 13 factors listed in S.C. Code § 20-3-130(C). Unlike states such as Texas or Colorado that cap alimony at a percentage of the payor's income, South Carolina grants judges full discretion to set both the amount and duration of support.
Because South Carolina has no statutory formula, any alimony estimator for this state must rely on historical case outcomes and the relative weight judges assign to each factor. A common benchmark used by South Carolina family law attorneys is 20% to 33% of the income difference between spouses for periodic alimony in marriages lasting 10 or more years, though this is an informal guideline rather than a legal rule. For a marriage of 20 years where the higher-earning spouse earns $120,000 and the lower-earning spouse earns $40,000, a spousal support calculator might estimate monthly alimony between $1,333 and $2,200 per month based on this range. Courts may award more or less depending on the specific circumstances.
The duration of alimony in South Carolina also varies. Rehabilitative alimony might last 2 to 5 years while the supported spouse completes education or job training. Periodic alimony in long-term marriages (20+ years) may continue indefinitely until the death of either party, remarriage, or cohabitation by the supported spouse for 90 or more consecutive days under S.C. Code § 20-3-130(B).
What Are the 13 Statutory Factors Courts Use to Calculate Alimony in South Carolina?
South Carolina family courts must consider all 13 factors listed in S.C. Code § 20-3-130(C) when determining alimony awards. No single factor controls the outcome, and courts weigh each factor against the unique circumstances of the marriage. The 13 factors are the foundation of every alimony calculation in South Carolina.
- Duration of the marriage, including the ages of each spouse at the time of marriage and at the time of divorce
- Physical and emotional condition of each spouse
- Educational background of each spouse and the need for additional training or education to achieve income potential
- Employment history and earning potential of each spouse
- Standard of living established during the marriage
- Current and reasonably anticipated earnings of both spouses
- Current and reasonably anticipated expenses and needs of both spouses
- Marital and nonmarital properties of each party, including those apportioned in the equitable distribution under S.C. Code § 20-3-620
- Custody of children, particularly where circumstances render it appropriate that the custodian not seek outside employment
- Marital misconduct or fault of either or both parties, including adultery, cruelty, or desertion, as it affects the economic circumstances of the parties
- Tax consequences to each party resulting from the form of support awarded
- Existence and extent of any support obligation from a prior marriage or other reason
- Any other factors the court considers relevant to the alimony determination
Factor 10 (marital misconduct) carries particular weight in South Carolina. Under S.C. Code § 20-3-130(A), a spouse who commits adultery before the earliest of (a) the formal signing of a written property or marital settlement agreement or (b) entry of a permanent order of separate maintenance and support is barred from receiving alimony entirely. South Carolina is one of only a handful of states that impose a complete adultery bar on spousal support.
What Are the Four Types of Alimony Available in South Carolina?
South Carolina courts may award four distinct types of alimony under S.C. Code § 20-3-130(B): periodic alimony, lump-sum alimony, rehabilitative alimony, and reimbursement alimony. Courts may also combine multiple forms of alimony in a single order. Each type has different rules for modification and termination.
| Alimony Type | Duration | Modifiable | Terminates On |
|---|---|---|---|
| Periodic (Permanent) | Ongoing until termination event | Yes, upon changed circumstances | Death of either spouse, remarriage, or 90+ day cohabitation |
| Lump Sum | Fixed total paid at once or in installments | No | Death of supported spouse only |
| Rehabilitative | Temporary (typically 2-5 years) | Yes, upon unforeseen events | Remarriage, cohabitation, death, or specific event |
| Reimbursement | Fixed total paid at once or in installments | No | Remarriage, cohabitation, or death of either spouse |
Periodic alimony is the most common form awarded in South Carolina divorces and consists of regular weekly or monthly payments. South Carolina courts award periodic alimony most frequently in marriages lasting 15 or more years where one spouse sacrificed career advancement to support the household. In shorter marriages (under 10 years), rehabilitative alimony is more typical, providing temporary support while the lower-earning spouse gains education or job skills to become self-supporting.
Reimbursement alimony addresses situations where one spouse made significant financial or personal contributions to the other spouse's career advancement. For example, if one spouse worked full-time to fund the other's medical school education, the supporting spouse may receive reimbursement alimony to compensate for that investment. Lump-sum alimony provides a finite total that cannot be modified regardless of changed circumstances, making it the most predictable form of South Carolina spousal support.
How Do South Carolina Courts Determine the Amount and Duration of Alimony?
South Carolina judges determine alimony amounts by comparing each spouse's gross income, reasonable monthly expenses, and the standard of living maintained during the marriage. The court examines tax returns, pay stubs, financial declarations, and monthly expense affidavits from both parties. South Carolina Family Court Rule 20 requires both spouses to file detailed financial declarations disclosing all income, assets, debts, and monthly expenses.
As a general framework, South Carolina courts consider the supported spouse's reasonable needs in light of the marital standard of living, minus that spouse's own earning capacity. If a couple maintained a $10,000 per month lifestyle and the lower-earning spouse earns $3,000 per month, the court may award alimony sufficient to bridge part or all of the $7,000 gap, depending on the payor's ability to pay and the other 12 statutory factors.
Duration is heavily influenced by the length of the marriage. South Carolina case law suggests the following general patterns:
- Marriages under 10 years: Rehabilitative alimony for 1 to 5 years is most common
- Marriages of 10 to 20 years: Periodic alimony for a set term (often one-third to one-half the length of the marriage) or rehabilitative alimony
- Marriages over 20 years: Permanent periodic alimony is most likely, especially if the supported spouse is over age 50 or has limited employability
These are informal guidelines observed in South Carolina family court practice, not statutory rules. Judges retain full discretion to deviate based on the 13 factors in S.C. Code § 20-3-130(C).
How Does Adultery Affect Alimony in South Carolina?
Adultery is an absolute bar to receiving alimony in South Carolina under S.C. Code § 20-3-130(A). A spouse who engages in adultery before the formal signing of a written settlement agreement or before entry of a permanent court order forfeits all rights to spousal support, regardless of financial need or the length of the marriage. South Carolina is among the strictest states in the nation on this issue.
The adultery bar applies only to the spouse seeking alimony, not the payor. If the higher-earning spouse committed adultery, the lower-earning spouse can still receive alimony and the affair may be considered under factor 10 (marital misconduct) as a basis for increasing the award. Conversely, if the lower-earning spouse committed adultery, that spouse receives nothing in spousal support even after a 30-year marriage.
The cutoff date is critical: adultery must occur before the earlier of (a) signing a written property or marital settlement agreement or (b) entry of a permanent order of separate maintenance and support. Conduct after these dates does not trigger the adultery bar. South Carolina courts require clear and convincing evidence of adultery, including opportunity and inclination, to impose this bar.
How Does Cohabitation Affect Alimony Payments in South Carolina?
Cohabitation by the supported spouse terminates periodic alimony automatically in South Carolina under S.C. Code § 20-3-130(B). The statute defines "continued cohabitation" as residing with another person in a romantic relationship for 90 or more consecutive days. This 90-day threshold is one of the most specific cohabitation standards in the United States.
The cohabitation rule applies only to periodic alimony. Lump-sum alimony is not affected by cohabitation because it represents a fixed, non-modifiable financial obligation. Reimbursement alimony terminates upon cohabitation, but rehabilitative alimony also terminates if the supported spouse begins cohabiting during the rehabilitative period.
To invoke the cohabitation termination, the payor spouse must file a motion with the Family Court and prove the supported spouse has been residing with a romantic partner for at least 90 consecutive days. Occasional overnight stays do not meet this threshold. The burden of proof falls on the payor to demonstrate continuous cohabitation through evidence such as shared utility bills, lease agreements, mail delivery records, or witness testimony. Once proven, the court must terminate periodic alimony — it is mandatory, not discretionary.
How Does Property Division Interact with Alimony in South Carolina?
South Carolina uses equitable distribution to divide marital property under S.C. Code § 20-3-620, meaning assets are divided fairly but not necessarily 50/50. The property division directly affects alimony calculations because factor 8 of the 13 statutory factors requires courts to consider the marital and nonmarital properties apportioned to each spouse.
In practice, a spouse who receives a larger share of the marital estate may receive less alimony, and vice versa. For example, if one spouse receives the family home (valued at $400,000 with $200,000 in equity) plus retirement accounts worth $150,000, the court may reduce alimony to account for the $350,000 in assets received. Conversely, a spouse who receives fewer assets may receive higher or longer-duration alimony to compensate.
South Carolina courts consider 15 separate factors under S.C. Code § 20-3-620 for property division, including the duration of the marriage, marital misconduct, each spouse's contribution to the acquisition of marital property (including homemaker contributions), and the current and reasonably anticipated income of each spouse. In long-term marriages, deviations beyond a 60/40 split are rare in South Carolina family courts. The interplay between property division and alimony means that both issues must be analyzed together rather than in isolation.
What Filing Fees and Court Costs Apply to Alimony Cases in South Carolina?
The filing fee for a divorce action in South Carolina Family Court is $150 as of March 2026. This fee covers the initial Summons and Complaint for Divorce filed with the Clerk of Court.

Are There Pending Alimony Reform Bills in South Carolina for 2026?
Several alimony reform bills are pending in the South Carolina legislature during the 2025-2026 session that could significantly change how spousal support is calculated. Bill 3098 proposes eliminating periodic alimony entirely and replacing it with a marriage-length-based formula. Bill 3074 would limit periodic alimony to marriages lasting at least 15 years. Bill 3029 would require federal spousal benefits to offset alimony owed by the payor spouse.
One proposed formula under consideration would award alimony for 1 year per every 3 years of marriage, meaning a 15-year marriage would result in a maximum of 5 years of alimony. Under this framework, alimony would terminate upon cohabitation of the supported spouse, retirement age of the payor, or death of either party. None of these bills have been enacted as of March 2026, and the existing law under S.C. Code § 20-3-130 remains in effect.
Bill 3009 would authorize the South Carolina Department of Social Services' Division of Child Support Enforcement to enforce alimony obligations, which would give alimony recipients the same enforcement tools currently available for child support collection. These proposed changes reflect a nationwide trend toward more predictable, formula-based alimony systems, though South Carolina has not yet adopted any of these reforms.
Frequently Asked Questions About Alimony in South Carolina
How is alimony calculated in South Carolina?
South Carolina has no fixed alimony formula. Family courts weigh 13 statutory factors under S.C. Code § 20-3-130(C), including marriage length, income disparity, standard of living, and marital fault. A common informal benchmark is 20% to 33% of the income difference between spouses for periodic alimony in marriages lasting 10 or more years, but judges retain full discretion.
How long does alimony last in South Carolina?
Alimony duration in South Carolina depends on the type awarded and the length of the marriage. Rehabilitative alimony typically lasts 2 to 5 years. Periodic alimony in marriages over 20 years may continue indefinitely until death, remarriage, or 90-day cohabitation under S.C. Code § 20-3-130(B). Lump-sum alimony terminates only upon the death of the supported spouse.
Can alimony be modified in South Carolina?
Periodic and rehabilitative alimony can be modified in South Carolina upon proof of a substantial change in circumstances. Lump-sum and reimbursement alimony cannot be modified once ordered. Common grounds for modification include job loss, significant income changes exceeding 15% to 20%, serious illness, or retirement. The party seeking modification must file a motion with the Family Court.
Does adultery affect alimony in South Carolina?
Adultery is a complete bar to receiving alimony in South Carolina under S.C. Code § 20-3-130(A). A spouse who commits adultery before signing a settlement agreement or before entry of a permanent court order forfeits all spousal support rights regardless of financial need. South Carolina requires clear and convincing evidence of opportunity and inclination to prove adultery.
What is the residency requirement to file for divorce and seek alimony in South Carolina?
South Carolina requires at least 1 year of residency by one spouse to file for divorce under S.C. Code § 20-3-30. If both spouses reside in South Carolina, the residency requirement drops to 3 months. The divorce must be filed in the county where the defendant resides or, if the defendant is a non-resident, in the county where the plaintiff resides.
Does cohabitation end alimony in South Carolina?
Cohabitation terminates periodic alimony in South Carolina when the supported spouse resides with a romantic partner for 90 or more consecutive days under S.C. Code § 20-3-130(B). The payor must file a motion and prove continuous cohabitation through evidence such as shared bills, lease agreements, or witness testimony. Lump-sum alimony is not affected by cohabitation.
Can I receive alimony if I earn more than my spouse in South Carolina?
Alimony in South Carolina is gender-neutral — either spouse can request it regardless of gender. However, the court considers the income disparity between spouses as a primary factor. If you earn more than your spouse, it is unlikely a court would award you alimony because the purpose of spousal support under S.C. Code § 20-3-130 is to address financial imbalance, not to supplement income.
How much does a contested alimony case cost in South Carolina?
A contested alimony case in South Carolina typically costs $10,000 to $28,000 or more in attorney fees, depending on the complexity of financial issues, the need for expert witnesses (forensic accountants cost $3,000 to $15,000), and trial duration. The $150 filing fee is just the starting point. Under S.C. Code § 20-3-130, the court may order one spouse to pay the other's attorney fees based on each party's financial resources.
Is alimony taxable in South Carolina?
Alimony payments under divorce agreements executed after December 31, 2018 are not deductible by the payor and not taxable income to the recipient under the federal Tax Cuts and Jobs Act of 2017. South Carolina follows this federal treatment. For agreements executed before January 1, 2019, alimony remains deductible by the payor and taxable to the recipient unless the agreement has been modified to adopt the new rules.
What happens to alimony if my ex-spouse remarries in South Carolina?
Remarriage of the supported spouse automatically terminates periodic alimony in South Carolina under S.C. Code § 20-3-130(B). Rehabilitative and reimbursement alimony also terminate upon remarriage. Lump-sum alimony does not terminate upon remarriage because it represents a fixed financial obligation. The payor must still file a motion to formally end periodic alimony payments even though termination is mandatory upon remarriage.
