Georgia Alimony Calculator (2026)

Under O.C.G.A. §§ 19‑6‑1 and 19‑6‑5, Georgia law bars alimony entirely when a spouse’s adultery or desertion caused the separation, and otherwise leaves the amount to the judge’s discretion. This calculator provides a rough estimate based on the American Academy of Matrimonial Lawyers’ rule‑of‑thumb, not a legal requirement.

Georgia has no statutory alimony formula. Courts decide case by case under O.C.G.A. §§ 19-6-1, 19-6-5. The calculator below shows a widely used rule of thumb (the AAML guideline) as a negotiation starting point — it is not the law and a judge may land anywhere the factors justify.

The law behind this calculator: Georgia alimony factors (adultery bar) — O.C.G.A. §§ 19-6-1, 19-6-5.

How Georgia calculates it

  • Calculate 30% of the higher‑earning spouse’s gross annual income.
  • Calculate 20% of the lower‑earning spouse’s gross annual income.
  • Subtract the lower‑earner result from the higher‑earner result.
  • Apply the 40% cap so the recipient’s total income does not exceed 40% of the combined income.
  • Determine the duration by applying the percentage of marriage length: 30% for marriages under 3 years, 50% for 3–10 years, 75% for 10–20 years, and indefinite for over 20 years.

Worked example

In the worked example, the higher earner makes $100,000 per year and the lower earner makes $40,000 per year in a 12‑year marriage: 30% × $100,000 = $30,000; 20% × $40,000 = $8,000; the difference is $22,000 per year, reduced to $16,000 by the 40% cap, which is approximately $1,333 per month as a rule‑of‑thumb starting point. The duration guide for a 12‑year marriage (10–20 years) is 75% of 144 months, roughly 108 months. The court is not bound by any of this.

Frequently asked questions

Can a spouse who committed adultery receive alimony in Georgia?

No. Georgia law bars alimony entirely to a spouse whose adultery or desertion caused the separation, per O.C.G.A. § 19‑6‑1.

How is alimony taxed in Georgia?

Georgia follows the federal treatment: for divorces finalized after December 31 2018, alimony is not deductible by the payer and is not taxable to the recipient; earlier divorces follow the pre‑TCJA rules.

How long could alimony last for a 2‑year marriage?

The rule‑of‑thumb suggests a duration of 30% of the marriage length, so roughly 7 months for a 2‑year (24‑month) marriage, though the court ultimately decides.

If I earn $100,000 and my ex earns $40,000, what rough monthly alimony might I pay?

Using the guideline: 30% × $100,000 = $30,000; 20% × $40,000 = $8,000; difference = $22,000; capped at 40% of combined income reduces it to $16,000 per year, about $1,333 per month.

Has Georgia changed its alimony guidelines recently?

Georgia has no statutory alimony formula and has not adopted the AAML guideline; the only recent statutory change is the adultery bar in § 19‑6‑1.

Is the calculation different in Atlanta, Augusta or Savannah?

No. O.C.G.A. §§ 19-6-1, 19-6-5 applies statewide, so courts in Atlanta, Augusta, Savannah and every other county start from the same guideline. Local practice can differ in how judges weigh deviation factors and in typical negotiated outcomes, but the formula on this page is the one used across Georgia.
