Appendix: How Much Is Alimony in Your State?
For an overview of the study and its findings, visit the study's main page. Find details on our methods below.
Study details
The results are estimates, designed to spur conversation and not to predict alimony for a particular case. The study did not account for financial variables like tax exemptions and health insurance premiums.
The formulas we used for California, Pennsylvania and Virginia are for alimony while a divorce is processing (called temporary alimony or pendente lite alimony). These states don't have a formula for alimony after a divorce has been finalized.
We excluded Massachusetts from the study. Although its divorce code provides a guideline alimony formula, some judges don't consider income used in a child support calculation, making alimony unpredictable in divorces involving minor children.
We also excluded Maryland. The "Kauffman" formula popular there is so complex that it requires software. Its results change based on variables this study did not consider.
We rounded to the nearest dollar, and we rounded partial months down.
We released our results in January 2024.

Sources
Amount
Formula
40% of the higher gross monthly income – 50% of the lower gross monthly income
When added to the gross income of the recipient, it shall not result in the recipient receiving in excess of 40% of the parties' combined monthly adjusted gross income.
Calculation
 $5,417 x 40% = $2,167
 $2,917 x 50% = $1,459
 $2,167 – $1,459 = $708
Next, we determined 40% of the combined gross income:
 $5,417 + $2,917 = $8,334
 $8,334 x 40% = $3,334
Finally, we determined how much alimony the wife could receive without going over 40% of the combined gross income:
 $3,334 – $2,917 (wife's income) = $417
Duration
According to the table in the statutes, 96 months of marriage equates to 39 months of spousal maintenance.

Amount
Formula
33 ⅓% of the payor's net annual income – 25% of the payee's net annual income
However, when added to the net income of the payee, it shall not result in the payee receiving an amount greater than 40% of the combined net income.
Calculation
 $49,754 x 33.3% = $16,568
 $24,923 x 25% = $6,231
 $16,568 – $6,231 = 10,337
Next, we determined 40% of the combined net income:
 $49,754 + $24,923 = $74,677
 $74,677 x 40% = $29,871
Finally, we determined how much alimony the wife could receive without going over 40% of the combined gross income:
 $29,871 – $24,923 = $4,948
 $4,948 / 12 = $412
Duration
Formula
For a marriage 8 years or more but less than 9 years, multiplying the length by .36

Many law blogs, such as Willick Law Group and Family Law Solutions, say judges regularly use the "Tonopah" formula. We used the gross version.
Amount
Formula
 Calculate the difference in gross incomes (subtracting child support from the obligee)
 Add up the following appropriate percentages:
 .75% for each additional year of marriage after 5 years
 5% if high school education
 .375% for each year of age of the obligee which exceeds the age of 30
 Multiply that cumulative percentage (up to 50%) by the difference in gross incomes
Calculation
Dad's gross income minus child support (calculated with the child support worksheet)
 $5,417 – $550 = $4,867
Difference in gross incomes
 $4,867 – $2,917 = $1,950
Percentages to multiply by
 Marriage lasted 8 years: .75 x 3 = 2.25%
 Wife has high school degree: 5%
 Wife is 40 years old: .375 x 10 = 3.75%
 Total percentage: 2.25 + 5 + 3.75 = 11%
$1,950 x 11% = $215
Duration
Formula
Add up the following:
 .375 years for each additional year of marriage after 5 years
 1.5 years if high school education
 .1 years for each year of age of the obligee which exceeds the age of 30
Calculation
Marriage lasted 8 years: .375 x 3 = 1.1 years
Wife has high school degree: 1.5 years
Wife is 40 years old: .1 x 10 = 1 year
Total percentage: 1.1 + 1.5 + 1 = 3.6 years x 12 = 43 months

Amount
Formula
The lesser of:
 20% of payor's net annual income – 25% of payee's net annual income
 40% of combined net income – payee's net annual income
Calculation
 $49,754 x 20% = $9,951
 $24,923 x 25% = $6,231
 $9,951 – $6,231 = $3,720
 $3,720 / 12 = $310
Next, we determined 40% of the combined net income and subtracted the wife's net income:
 $49,754 + $24,923 = $74,677
 $74,677 x 40% = $29,871
 $29,871 – $24,923 = $4,948
 $4,948 / 12 = $412
The lesser of the two results is $310.
