How Mortgage Lenders Calculate Your Income
Base pay, overtime, bonus, commission, part time work and second jobs are each calculated differently. Here is what counts and how averaging works.
Updated 2026-08-21| Applies to: Anyone with variable pay, multiple jobs or non salary income.
The short answer
Lenders use qualifying income, not gross pay on a good month. Salary is usually taken at face value, while variable income like overtime, bonus, commission and second jobs is typically averaged over a history and must be likely to continue. Income that cannot be documented and averaged generally cannot be used.
Two people who earn the same amount can qualify for very different loans, because the way income is structured changes how much of it counts.
How each type is generally treated
| Income type | Typical treatment |
|---|---|
| Salary | Current gross annual amount |
| Hourly with steady hours | Hourly rate times documented average hours |
| Overtime, bonus, commission | Averaged over a documented history and must be likely to continue |
| Part time or second job | Usually requires a history in the role or the field |
| Self employment | Net income from tax returns with certain add backs, averaged |
| Retirement, Social Security, pension | Documented award or distribution history and continuance |
| Rental income | Calculated from leases or tax schedules with a vacancy factor |
Continuance matters as much as history
Income with a defined end date, such as a contract ending or a benefit that expires soon, may be limited or excluded. Income that is documented, stable and likely to continue is what supports a payment.
What to send
- Recent pay stubs covering a full month
- W 2s or 1099s for the last two years
- Full personal and business tax returns if self employed
- Award letters or benefit statements for retirement and disability income
- Leases and the applicable tax schedules for rental income
Calculation rules differ by loan program and lender. General education, not a commitment to lend.
