How does FHA calculate overtime and bonus income?
SHORT ANSWER
FHA averages overtime and bonus income over the previous 2 years to calculate effective income for qualifying purposes. If the current year’s income drops 20% or more from the previous year, the lender must use the current year’s lower figure instead. Smart Loan Savings Educational Content

| Target Element Name | Underwriting Impact on Your FHA Loan Profile |
|---|---|
| AUS Refer Finding | A computer cannot issue an approval on your FHA home loan file. A person then underwrites your file by hand for a closer look. Overtime and bonus income calculations frequently require this manual underwriting, since averaging 2 years of variable pay and checking for a 20% decline is not something the computer system performs on its own. In practice, a borrower whose overtime income increased steadily over 2 years often sees a smoother path through the computer system, while a borrower with a recent decline often needs the underwriter to manually apply the current-year rule instead of a straight average. A borrower assuming the computer system automatically catches an income decline should understand this specific calculation often requires a human underwriter to apply correctly. Confirming both years of overtime figures early in the process helps a borrower anticipate whether manual underwriting is likely. |
| The 20 Percent Decline Rule Overrides the Standard Average | Borrowers who assume FHA automatically averages overtime and bonus income over 2 years regardless of trend are often surprised to learn a specific decline threshold overrides that standard method entirely. HUD 4000.1 requires the lender to abandon the 2-year average and use only the current year’s figure once overtime or bonus income drops 20% or more from the previous year. A borrower whose overtime fell from $20,000 to $14,000 would qualify using the lower $14,000 figure, not an average of both years. This distinction matters because a borrower estimating their own qualifying income using a simple average may significantly overestimate what the underwriter actually uses once a meaningful decline has occurred. Confirming both years of documented overtime or bonus figures before assuming a specific qualifying number can save a borrower from a mismatched expectation heading into underwriting. |
| The 1-Year Exception for Newer Overtime | The detail many borrowers miss until a loan officer explains it is that a full 2-year history is not automatically required to use overtime or bonus income. HUD 4000.1 allows the lender to consider Effective Income from overtime or bonus pay earned for as little as 1 year, provided the lender documents that the income has been consistently earned and is reasonably likely to continue. A borrower who recently moved into a role with regular overtime, without a full 2 years behind them yet, may nonetheless qualify to use that income under this specific exception. Confirming eligibility for this 1-year exception before assuming overtime cannot be used at all can open up real qualifying income a borrower might otherwise overlook. This exception is genuinely underused by borrowers who assume a shorter overtime history disqualifies the income entirely. |
| Volatile Income Requires More Than 2 Years | The threshold that often surprises borrowers is that a standard 2-year average is not automatically the final word when overtime or bonus income swings significantly from year to year. HUD’s own guidance requires the lender to use a period of more than 2 years to calculate the average when income varies significantly, rather than relying on just the 2 most recent years. A borrower with wildly inconsistent overtime, high one year and low the next, may see the lender pull additional years of history specifically to establish a more reliable trend. This additional scrutiny exists specifically to prevent a borrower from qualifying on an artificially high average built from just 1 unusually strong year mixed with a weaker one. A borrower with genuinely volatile overtime should expect this deeper look rather than assuming the standard 2-year window automatically applies. |
| The Debt-to-Income Ratio | Lenders check if your monthly bills fit the standard debt rules used across FHA programs. Overtime and bonus income feeds directly into this calculation, since the final effective income figure, whether averaged or based on the current year alone, becomes part of the income used against total monthly debts. The math runs like this: a borrower with $60,000 in base salary and a qualifying overtime average of $8,000 has a combined effective income of $68,000 used for the entire DTI calculation, not just the base pay. A borrower whose overtime income was excluded due to a declining trend or insufficient history should recalculate their DTI using base salary alone to get an accurate picture. Understanding exactly how overtime and bonus income factors into the final DTI figure helps a borrower avoid overestimating their true qualifying position. |

| People Also Ask | Why These Questions Matter |
|---|---|
| Can overtime pay be used to qualify for an FHA loan? | Overtime pay can be used to qualify for an FHA loan if it has been earned consistently and is reasonably likely to continue. HUD requires at least 1 year of documented history at minimum. A full 2-year history allows the standard averaging method instead of the shorter exception. |
| How does FHA calculate income from overtime or bonuses? | FHA calculates overtime or bonus income by averaging the amounts earned over the previous 2 years. A decline of 20% or more from the previous year requires using the lower current year’s figure instead. This averaging method applies regardless of whether the overtime came from 1 employer or multiple employers. |
| What happens if my overtime income varies a lot from year to year on an FHA loan? | If your overtime income varies significantly from year to year, HUD requires the lender to use a period of more than 2 years to calculate the average. This additional history helps establish a more reliable earnings trend. A continual decline also requires the lender to document a specific written justification for including the income at all. |
