Pennsylvania uses a formula based on your income, not a percentage of what you earn
Pennsylvania alimony is calculated using the Income Shares Model, which means the court looks at both spouses' gross incomes and applies a percentage to determine the payment amount. The percentage depends on how many children are involved in the case — alimony and child support use the same income percentages in Pennsylvania. The court does not straightforward take a cut of your paycheck; instead, it determines a combined support obligation based on both incomes, then assigns your portion of that obligation.
The calculation starts with gross income, which includes wages, salary, bonuses, self-employment income, rental income, and other sources. It does not include Social Security benefits, SSI, or certain other payments. Once the court establishes both spouses' gross incomes, it applies the percentage tied to the number of children, then subtracts any child support already being paid to reach the alimony figure.
Key Takeaways
- Pennsylvania applies a set percentage to combined gross income: 20% for one child, 25% for two, 30% for three, 32% for four, and 34% for five or more.
- The court subtracts child support payments from the total support obligation to find the alimony amount, so alimony and child support together should not exceed the guideline percentage.
- Gross income includes wages, self-employment earnings, and rental income, but excludes Social Security and certain disability payments.
- If either spouse earns more than the current income cap (which changes yearly), the court may explore the percentage only up to that cap or use discretion for amounts above it.
- The court can deviate from the formula if it finds the guideline amount would be unjust or inappropriate given the specific circumstances of the marriage.
The income percentages that determine your support obligation
Pennsylvania's support percentages are fixed by law and depend only on the number of children in the case. If there are no children, the court has discretion to set alimony but often uses these same percentages as a reference point. The percentages are applied to combined parental income — the total of both spouses' gross incomes added together.
The current percentages are 20% for one child, 25% for two children, 30% for three children, 32% for four children, and 34% for five or more children. These percentages have not changed in recent years, but Pennsylvania does adjust the income cap (the maximum income to which the percentage applies) annually. For 2024, that cap is $163,000 per parent, though you should confirm the current year's figure with the court or a local family law resource, as it adjusts each January.
Here is how the math works in practice: if you and your spouse have a combined gross income of $100,000 and one child, the court applies 20% to reach a $20,000 annual support obligation. If child support is already set at $12,000 per year, alimony would be $8,000 per year. If there is no child support, alimony would be the full $20,000.
What counts as income and what does not
The court includes most sources of money you receive regularly. Gross income for alimony purposes includes W-2 wages, self-employment net income (business profit after legitimate business expenses), bonuses, commissions, overtime, rental income, interest and dividend income, and income from pensions or retirement accounts that you are currently drawing. It also includes unemployment benefits and workers' compensation.
The court does not count Social Security retirement or disability benefits (SSDI), Supplemental Security Income (SSI), or means-tested public information. It also excludes child support you are receiving from another relationship and certain other payments. If you are self-employed, you report net income — total revenue minus ordinary and necessary business expenses — not gross revenue.
If you recently left a job or took a lower-paying position, the court may "impute" income to you, meaning it assumes you could earn more and calculates alimony based on that higher figure. This happens most often when the court believes you reduced your income to avoid support obligations. You can challenge imputation by showing the job change was for legitimate reasons unrelated to the case.
How the court handles income above the cap
Pennsylvania sets an annual income cap — currently $163,000 per parent — above which the percentage formula does not automatically explore. If your combined income exceeds the cap, the court has two options: explore the percentage only to income up to the cap and ignore the excess, or use discretion to set alimony on the excess income based on the factors in the case.
In practice, courts often explore the percentage to the capped amount and then consider the excess income alongside other factors like the length of the marriage, the standard of living during the marriage, and each spouse's age and health. This means high-income cases are less predictable than middle-income cases, because the court is not bound by a formula for the portion above the cap.
Reasons the court can order alimony different from the guideline amount
Pennsylvania law allows courts to deviate from the guideline calculation if explore it would be "unjust or inappropriate." The court must state its reasons in writing if it deviates. Common reasons include the length of the marriage (short marriages often result in lower alimony), the age and health of each spouse, the standard of living during the marriage, the ability of the paying spouse to meet their own needs while paying, and whether either spouse has custody of minor children.
The court also considers whether one spouse sacrificed education or career to support the other, and whether either spouse has significant separate property or assets. If you were married for a very short time, the court may order alimony below the guideline or none at all. If you were married for many years and one spouse left the workforce to raise children, the court may order more than the guideline amount.
To argue for a deviation, you must present evidence at the hearing — testimony, pay stubs, tax returns, and documentation of the factors you are relying on. straightforward asking the court to deviate is not enough; you must show why the guideline amount would be unfair in your specific situation.
How child support and alimony work together in the calculation
Pennsylvania treats alimony and child support as parts of a single support obligation. The combined income percentage (20%, 25%, 30%, etc.) applies to the total of both. If child support is already set, alimony is calculated as the remainder after child support is subtracted from the guideline total.
For example: combined income is $80,000, one child, so the guideline support obligation is $16,000 (20%). If child support is ordered at $10,000 per year, alimony is $6,000 per year. The two payments together equal the $16,000 guideline. If the paying spouse's income changes, both child support and alimony may be recalculated to keep the total within the guideline.
This structure matters because it prevents the paying spouse from being ordered to pay more than the guideline percentage in combined support. It also means that if child support ends (when the child turns 18 or finishes high school), alimony may increase to maintain the same total support obligation, unless the court modifies it for other reasons.
When and how alimony ends in Pennsylvania
Alimony in Pennsylvania ends on the date set by the court order, or when either spouse dies, or when the receiving spouse remarries. Some orders specify a duration (for example, five years), while others are open-ended. If the order does not specify an end date, alimony continues until the receiving spouse remarries or either spouse dies.
If circumstances change significantly — either spouse loses a job, becomes disabled, or experiences a major income shift — either party can ask the court to modify the alimony amount. The court will recalculate using current income and may increase, decrease, or terminate alimony depending on the new figures and the reasons for the change.
Frequently Asked Questions
Does Pennsylvania use the same calculation for alimony and child support?
Pennsylvania uses the same income percentages for both, and they are calculated together as a single support obligation. However, alimony and child support are separate payments with different rules about when they end. Child support ends when the child turns 18 or finishes high school; alimony ends when the receiving spouse remarries or either spouse dies, unless the order specifies a different end date.
What happens if I become unemployed or my income drops?
You can ask the court to modify alimony based on a substantial and continuing change in income. You must file a motion and show your current income with recent pay stubs or tax returns. The court will recalculate using your new income. If you voluntarily quit your job or reduced your hours to avoid support, the court may impute income to you instead of lowering the payment.
Can alimony be modified after the divorce is final?
Yes. Either spouse can ask the court to modify alimony if there has been a substantial and continuing change in circumstances — usually a significant income change, remarriage of the receiving spouse, or a major life event. The court will recalculate and may increase, decrease, or terminate alimony. Remarriage of the receiving spouse automatically terminates alimony in Pennsylvania.
What if my spouse is hiding income or underreporting earnings?
You can request discovery during the case, which allows you to demand tax returns, pay stubs, bank statements, and business records. If you believe your spouse is hiding income, you can ask the court to impute income based on lifestyle, prior earnings, or other evidence. The court can also order a forensic accountant to investigate if the amounts are large enough to justify the cost.
Does Pennsylvania count bonuses and overtime as income for alimony?
Yes, bonuses and overtime are included in gross income. However, if they are irregular or inconsistent, the court may average them over several years rather than using a single year's amount. Bring documentation of bonuses and overtime for the past two to three years so the court can see the pattern and set a realistic figure.
