Averaging overtime, bonus and commission income from pay stubs
Overtime, bonus and commission change from stub to stub, so they are commonly averaged over a longer history instead of annualized from one period. A common approach totals the variable pay for a stated number of months, divides by those months, and compares recent months with the long-run average. Guidelines differ on the history required and on whether declining income counts.

Why variable pay is handled apart from base pay
Base pay repeats: a salary, or an hourly rate times regular hours. Overtime, bonus and commission may not. A busy month can double an overtime line, and an annual bonus lands on a single stub. Annualizing one such stub overstates income, while ignoring a long-standing pattern understates it.
So reviewers commonly split gross into base and variable pay, average the variable part over a longer history and look at the trend. The history required, whether a falling amount is used and what shows it will continue differ by lender, program and landlord, so this guide describes the usual mechanics only. Stubs cover recent weeks, so the longer history usually comes from the final stub of the prior year, and YTD income verification shows how the current-year total is read. Base pay conversions are in monthly income from pay stubs.
How variable pay is commonly averaged
The table after the steps works one example.
-
Separate the earnings lines
Read regular, overtime, bonus and commission on each stub, and keep their YTD figures if the stub prints them.
-
Choose the history
Guidelines commonly look at a year or two where available. Stubs give the current year to date, and last year's total comes from the final stub of that year.
-
Total the variable pay for each period
Use the current-year YTD from the latest stub and the prior-year total from the year-end stub.
-
Divide by the months covered
That is the months elapsed this year, 12 for the prior year, or the combined months when both are used together.
-
Compare recent months with the longer average
Rising, flat or falling matters. A falling trend is commonly handled with the lower figure, or the income is left out, depending on the guideline.
-
Record the support
Note whether the pay is expected to continue and what supports that, such as an employer statement, if the requester asks for it.
Worked example: overtime averaged four ways
Prior-year overtime was $9,600 on the year-end stub. The latest stub, paid September 30, shows $6,300 year to date over nine months.
| Method | Calculation | Monthly overtime | How it is commonly read |
|---|---|---|---|
| Prior year alone | $9,600 ÷ 12 | $800.00 | The earlier level, a baseline for the trend |
| This year to date | $6,300 ÷ 9 | $700.00 | The recent level, lower than last year |
| Both periods combined | ($9,600 + $6,300) ÷ 21 | $757.14 | A common form when two periods are available |
| Latest four stubs annualized | $400 per stub × 26 ÷ 12 | $866.67 | A warning case: a busy stretch inflates the figure |
Here the recent level ($700.00) sits below the combined average ($757.14), which a reviewer would note as a possible decline. Which figure counts, if any, is the guideline's call.
What goes wrong
-
Annualizing a busy stretch
Four stubs from a peak season give a monthly figure well above the year's average. Use a longer span.
-
A single bonus treated as regular
An annual bonus on one stub is spread over the months it covers. It is not multiplied by the pay periods in a year.
-
Mismatched months
Dividing a combined total by only 12, or this year's YTD by 12, misstates the average. The months in the denominator have to match the pay in the numerator.
-
Labels that hide the type
Differentials, incentive pay and premium pay are variable but may not be called overtime, bonus or commission. Read the line names, not just the totals.
-
A change of role or employer
History from a different job or pay plan may not carry over. Check whether the pay structure is the same.
-
Commission draws
An advance against future commission can show as pay before it is earned. Check how the employer labels it before averaging. For hourly workers, hourly income calculation keeps regular and overtime hours apart.
How VerifyStub helps
VerifyStub splits each stub's earnings into regular, overtime, bonus, commission, paid time off and other columns. It reports overtime, bonus and commission as a share of gross across the stubs you upload, plus a year-to-date share from the latest stub, so you can see how much of the income is variable before averaging anything. It does not compute multi-year averages or decide what counts; that step is yours under the requester's rules. Try the pay stub to CSV page (free: 1 file per day, up to 10 pages, no account) or see pricing.
Scope. VerifyStub checks arithmetic on the pay stubs you upload. It does not detect altered documents, verify employment or income, or give lending, legal or tax advice. Rules and policies differ by lender, program, landlord and jurisdiction.
Averaging variable income: common questions
How long a history is needed for overtime, bonus or commission?
It varies. Mortgage guidelines commonly look for around two years, sometimes less with an explanation, and some landlords count only documented recurring pay. Check the guideline that applies and follow its wording.
Should I use the average or the most recent figure?
An average over the history is common. When the recent figure is lower than the average, many guidelines use the lower one or leave the income out. A higher recent figure is commonly not used on its own.
How do I tell overtime from regular pay on a stub?
Read the earnings section. Overtime normally has its own line with its own hours and a higher rate, often 1.5 times the regular rate. Regular pay is the line for standard hours.
Do bonuses count as income?
Sometimes. Reviewers commonly ask whether the bonus has been paid regularly and is expected to continue. A one-off or discretionary bonus is often treated differently from a regular one. The requester's policy decides.
How is commission income usually handled?
Much like overtime and bonus: averaged over a longer history, with attention to the trend. Some programs also ask for tax returns when commission is a large share of income. Check the requirements that apply.
Where do I get last year's variable pay if I only have recent stubs?
From the final stub of the prior year, which shows year-to-date totals by earnings type if the payroll prints them. A W-2 does not split pay by type, so it cannot stand in for that stub here.
Does VerifyStub average overtime and bonus?
No. It reports each type's share of gross, and of year-to-date gross from the latest stub, so you can see how much is variable. The multi-period average and the decision about what counts belong to the person applying the guideline.
