Does Overtime or Bonus Income Count Toward a Mortgage?

The short answer: usually yes, and almost never at the number you have in your head. Overtime and bonus income generally count when there is a documented history of receiving it and a reasonable basis to expect it to continue. But it is averaged across that history rather than taken at your current rate — so a strong recent year gets flattened by the years behind it, and a declining trend can reduce it or knock it out entirely.

If your income is non-taxable rather than variable — Social Security, a pension, disability — the treatment runs the other way and usually in your favor; that is its own article. Two mistakes come from the variable case, and they are opposite mistakes. Some people assume variable income does not count at all and shop for a house well under what their file supports. Others take last year's total, divide by twelve, and shop for something they cannot document.

I'm Jeff Moran, a mortgage broker in Bluffton, South Carolina, originating since 1996. Variable income is one of the most common reasons a pre-approval number differs from what a client expected, and it is entirely predictable once you know what the calculation is doing.

What underwriting is actually asking

One question, and it governs every kind of income in a mortgage file: is it active, and is it reasonably likely to continue?

That is the whole test. It is not "did you earn it" — your W-2 already settles that. It is whether the money will still be arriving when the payment is due in year three.

Overtime and bonuses are treated cautiously for an obvious reason: they are the first thing that disappears when a business slows down. Base salary is contractual. Overtime is conditional. So the calculation asks for evidence rather than taking it at face value.

How the number gets built

Three steps, and the second one is where expectations break.

1. A documented history. Generally around two years of receiving the income, evidenced by W-2s, pay stubs showing year-to-date figures, and often a verification from the employer. The exact look-back and the exceptions vary by program, which is worth asking about rather than assuming.

2. Averaging. This is the step people do not expect. The income is averaged across the history period rather than taken at the current rate. If you earned considerably more in overtime this year than last, the average sits between them — not at the higher figure.

3. A trend check. If the current year is running below the prior year, the calculation generally does not use the higher figure just because it exists on a W-2. A meaningful decline can mean the lower number governs, and a sharp one can mean the income is set aside entirely as not likely to continue.

Base pay works differently, which is why the distinction matters. Your salary is your current salary — not last year's total, and not an average. It is the same principle that governs how a self-employed file gets calculated: what is stable and likely to continue, not what happened. It is the variable portion on top that gets the historical treatment.

Why a great year does not help as much as you think

This is the part worth internalizing before you shop.

Averaging cuts both ways and people only notice one direction. A year of heavy overtime raises the average, but only by its share of the whole period. Meanwhile a slow year drags on the average for as long as it stays in the window.

So the client who picked up enormous overtime in the last eight months, and who feels considerably wealthier than they did, frequently sees a qualifying number that has moved far less than their bank account has. Nothing is wrong. The calculation is doing what it was designed to do, which is describe income that is likely to persist rather than income that happened.

The reverse is also true and it is the encouraging half: a bad year eventually rolls out of the window.

What actually breaks these files

• Changing jobs into a role without the overtime, weeks before applying. The history exists; the likelihood of continuing does not.
• Starting a job that pays overtime with no history yet. New employment plus variable income generally means the variable part cannot be used yet, even when the pay stubs look excellent.
• A bonus that was explicitly one-time. A signing bonus, a retention payment, a one-off project award — documented as non-recurring, it does not count, and it should not.
• Assuming the employer will confirm it. Employers sometimes return a verification saying overtime is not guaranteed to continue, which is accurate and unhelpful. Knowing how yours answers is worth finding out early.
• Shopping on a number nobody calculated. The most expensive one. It costs weeks, and it usually costs the house.

The part that is genuinely good news

Most people underestimate this income, not overestimate it.

The client who says "I make about $70,000, but a lot of it is overtime so I assume it doesn't count" is usually wrong in a way that costs them. Two years of consistent overtime is exactly what the calculation is built to accept. It gets averaged and it gets scrutinized — and then it counts.

And because debt ratio is the constraint for most buyers, income that counts translates fairly directly into the payment a file supports — and therefore into the price range you should be shopping.

An illustration, so the shape is clear

Numbers below are invented to show the mechanism, not a quote.

Say your base salary is $60,000. Last year you also earned $18,000 in overtime. The year before, $10,000.

You are currently on pace for another strong overtime year, and mentally you are a $78,000 earner shopping accordingly.

The calculation sees it differently. Your base is your current base — $60,000, used as it is. The overtime is averaged across the two-year history, which lands closer to $14,000 than to $18,000. Your qualifying income comes out somewhere near $74,000, not $78,000.

That is a real difference in price range, and it is entirely knowable in advance.

Now run it the other way. If the two years had been $10,000 and then $6,000 — same total effort, declining shape — the number used would be at or below the lower figure, and a steep enough drop could remove the overtime from the calculation altogether. Same job, same employer, very different answer.

What to do now

Find out your number before you shop, not after you are under contract.

Bring two years of W-2s and your most recent pay stub, and the arithmetic takes minutes. It is the same work that goes into a real pre-approval, just done early enough to be useful. Run your scenario first if you want the payment picture — no credit pull, no account, nobody calls you — and then we can settle what your actual qualifying income is rather than estimating it.

If your variable income is a large share of your total, that conversation is worth having before you make any employment decision. It is the one input you can accidentally destroy in a week.

Nothing here is a loan approval, a denial, or a commitment to lend. Program guidelines differ and change, and what applies to a specific file is worth confirming rather than assuming.

Common questions

Does overtime count as income for a mortgage?

Generally yes, when there is a documented history of receiving it — usually around two years — and a reasonable basis to expect it to continue. It is averaged across that history rather than counted at your current rate, and the exact look-back varies by loan program. A verification from the employer confirming the overtime is likely to continue carries real weight.

How is bonus income calculated for a mortgage?

It is averaged over the documented history rather than taken at the most recent amount, and the trend matters. If the current year is running below the prior year, the lower figure generally governs, and a sharp decline can mean the income is set aside as not likely to continue. A bonus documented as one-time — a signing or retention payment — does not count at all.

Can I use overtime income if I just started the job?

Usually not yet. New employment combined with variable income generally means the variable portion cannot be used until there is a history behind it, even when the pay stubs look strong. The base salary from a new job is typically usable straight away, which is a meaningful distinction if a large share of your pay is variable.

Why is my qualifying income lower than what I actually earn?

Because base pay and variable pay are treated differently. Your base salary is used at its current rate, while overtime, bonus and commission are averaged across a two-year history and checked for whether they are trending down. A strong recent year gets flattened by the years behind it, which is why the qualifying figure often sits below what your most recent W-2 shows.

Does declining overtime hurt my mortgage application?

It can, and it is one of the few income issues that gets worse rather than better with time. When the current year runs below the prior year, the calculation generally will not use the higher figure, and a large enough decline can remove that income from consideration. If your hours have dropped recently, that is a reason to have the conversation sooner rather than waiting.

Should I take a promotion that pays less overtime before buying?

It is worth pricing before you decide. A move into salaried work can raise your base while removing variable income that had two years of history behind it, and the net effect on qualifying income is sometimes negative even when total pay rises. That is arithmetic that can be run in advance, and it is one of the few decisions that is genuinely easier to make with a lender in the room.
