How Lenders Treat Overtime, Bonus And Commission Income

Two applicants can deposit identical amounts each year and be treated as though they earn very different incomes. The difference is how much of that money an underwriter is willing to call stable.

Qualifying income is a projection, not a record

An underwriter is not asking what you earned last year. The question is what you are likely to earn during the years the loan will be outstanding, which is a forecast built from history.

Base salary answers that question easily. It is contractual, it arrives on a schedule, and the employer will confirm it in writing without qualification.

Overtime, bonus and commission answer it poorly. Each is contingent on business conditions, individual performance or hours that an employer is under no obligation to keep offering.

Why lenders average variable pay over years

The common approach is to average variable income across a period long enough to include a bad year. A single strong year is treated as an outlier rather than as the new normal.

That averaging cuts both ways. An applicant whose commissions have climbed steadily still qualifies on a figure well below current earnings, because the average is dragged down by earlier periods.

Where the trend runs downward, many lenders will not average at all. They use the most recent, lower figure on the reasoning that the decline may continue.

Documentation decides what can be counted

Variable pay usually has to appear in tax filings and payroll records covering more than one year, and the employer is often asked to confirm that it is expected to continue.

A job change resets much of this. Moving to a new employer, even at higher pay, can remove several years of documented history from the calculation.

Self-employment sits at the far end of the same logic. Business income is examined for consistency and for owner draws, and deductions that reduce reported profit also reduce qualifying income.

The effect on the debt-to-income calculation

Qualifying income sets the denominator in the ratio lenders use to cap borrowing. Excluding a bonus does not just remove that money; it shrinks the total debt payment the applicant is allowed.

This is why an applicant with strong cash flow can be told they are borrowing beyond their means. The lender is working from a smaller income figure than the bank account shows.

Reserves can soften the outcome. Savings that cover several months of payments give an underwriter something to weigh against income that varies.

Where the rules differ between lenders

Standards for variable income vary by loan program, by investor and by the individual lender's overlays, and they are revised as credit conditions change.

Two lenders can look at the same pay stubs and reach different qualifying figures. Asking each how it treats a specific income type is more useful than comparing advertised rates.

A loan officer or mortgage broker can say in advance which portions of pay will count, which avoids applying on an income figure the file will never support.
