How Lenders Count Bonus, Overtime and Commission Income

Why your pre-approval number doesn't match your paycheck

You pulled $118,000 last year. Your loan officer qualifies you on something closer to $92,000. Nothing is broken. This is how underwriting treats pay that moves around.

When part of your income is a bonus, overtime, commission, or tips, lenders class it as "variable income" and run it through an averaging test instead of counting your most recent, best stretch. The federal ability-to-repay rule is the backdrop: lenders must make a documented, good-faith finding that you can repay, and they generally have to verify income with reliable third-party records like W-2s and pay stubs. According to the Consumer Financial Protection Bureau, the ability-to-repay rule requires lenders to consider and document your income, assets, employment, credit, and monthly obligations before making the loan. A spiking bonus year, by itself, is not proof of durable income, so the rules force a more conservative read.

The practical result: your qualifying income is a calculated figure, not your gross pay. Understanding the formula before you shop keeps you from falling for a house your averaged income can't actually carry. If you want the broader picture of what underwriters weigh, our guide to what lenders actually evaluate during pre-approval pairs well with this one.

What lenders call "variable income"

Variable income is any pay that isn't a fixed salary or hourly base. According to Fannie Mae's Selling Guide, income calculated by an averaging method must be reviewed for history of receipt, frequency of payment, and the trend of the amount received. In plain terms, that covers four common buckets:

• Bonus: annual, quarterly, or discretionary payouts on top of base salary.
• Overtime: extra hours beyond your standard schedule, common in trades, nursing, manufacturing, and logistics.
• Commission: pay tied to sales or transactions, often the bulk of a salesperson's income.
• Tips: reported gratuity income, now grouped with bonus, commission, and overtime under the same averaging logic.

How you are paid matters as much as how much. A bonus paid once a year is divided by 12 to find its monthly contribution. If an annual bonus lands in March for the prior year, the full 12-month average is used, not a shorter window that happens to look richer. The lender is trying to answer one question: what can you reliably count on every month, not in your best month?

The two-year rule, and the 12-month exception

The headline standard is two years. For Fannie Mae, two or more years of receiving a variable income type is recommended, but income received for 12 to 24 months can be acceptable when positive factors reasonably offset the shorter history. Those offsets include a strong credit profile, significant reserves, a low debt-to-income ratio, or a documented, stable role.

Freddie Mac lands in a similar place through Guide Section 5303.1: bonus, commission, overtime, and tip income reported by an employer generally wants two years of consecutive history, with a history of at least one year potentially acceptable under its stability guidance, and continuance that is likely to keep going. Both agencies also lean on their automated underwriting systems, which can set the exact history required for a given file.

So a 12-month history is not an automatic no. It is a conditional yes that depends on everything else in your file. If your variable pay is brand new, say six months old, expect lenders to qualify you on base pay alone until the track record builds.

Stable or rising vs. declining: how the method changes

Once a lender confirms you have enough history, the trend decides the math. Fannie Mae's approach is straightforward: compare year-to-date earnings against prior years using W-2s or signed returns.

Stable or increasing

If the amount is steady or rising, the lender averages it. A common method blends your most recent year-to-date figure with the prior one or two full years. Say commission was $40,000 one year and $44,000 the next. That upward trend gets averaged, giving you roughly $42,000 to work with, divided by 12 for a monthly figure.

Declining

If the trend is down, the rules get cautious. When variable income is dropping, lenders generally use the current, lower amount rather than a two-year average that masks the decline, and they must be satisfied the income has stabilized at that lower level. A sharp drop can disqualify the income entirely. A useful rule of thumb from several agency summaries: a year-over-year fall of roughly 25% or more, without evidence of stabilizing, can mean the income isn't counted at all. The logic is simple. If your commission is shrinking, the lender won't bet your mortgage on it bouncing back.

How FHA treats the same income

FHA loans follow HUD's Single Family Housing Policy Handbook 4000.1, and the differences are worth knowing, especially if your file is tight. According to HUD, a lender may use overtime, bonus, or tip income as effective income if the borrower has received it for the past two years and it is reasonably likely to continue, with shorter periods allowed when the lender documents that the income has been consistently earned over not less than one year.

The calculation is where FHA is noticeably strict. For overtime and bonus income, FHA generally averages the income earned over the previous two years, and uses the lesser of two averages when the trend is uneven. A current-year decline of 20% or more triggers extra scrutiny and a more conservative figure. For commission, FHA leans on the share of your income it represents: when commission is 25% or more of your total annual earnings, the lender treats you much like a self-employed borrower and wants tax returns rather than a W-2 alone. That is a bigger documentation lift, so if most of your pay is commission, read our walkthrough of how self-employed and commission-heavy borrowers get approved before you apply.

The documents lenders will ask for

Verification is the whole game. The CFPB requires lenders to confirm income using reasonably reliable third-party records, so expect to produce paper that proves both the amount and the history. Here is the typical stack for variable income.

Any gap, a missing stub, a bonus the employer won't confirm as recurring, a return showing heavy write-offs, can shrink the income the lender counts. Incomplete paper is also a leading reason files stall, as our guide to the underwriting conditions that delay closings explains.

Match your budget to your real qualifying income

A strong buyer's agent helps you target homes your averaged income supports, not your best bonus year, so your offer holds up through underwriting and appraisal.

The honest warning: don't buy off your best year

Here is the counterpoint most marketing won't tell you. Even when a lender does count a big bonus or commission year, leaning on it to stretch your budget is risky if that income isn't likely to repeat. Variable pay is variable for a reason. Commission dries up when the market cools. Overtime vanishes when the plant cuts shifts. Bonuses get trimmed when the company misses targets.

The averaged number the lender gives you is usually the smarter number to budget from, not your peak. If you buy at the top of what a record year supports, a normal year can turn a comfortable payment into a monthly squeeze. And the fixed costs of a home keep climbing regardless of your commissions, which is why it helps to see realistically how much income it takes to buy in your city before you commit.

How to protect your qualifying income

You can't rewrite the rules, but you can keep from tripping over them. Watch for these red flags before you apply.

• Switching jobs mid-process. A new employer resets your history for that income type. If a move is coming, talk to a lender about timing before you quit.
• A down year you can't explain. A sharp decline can knock the income out. Gather documentation of the cause and any recovery before the underwriter asks.
• Heavy tax write-offs on commission. Big unreimbursed expenses lower the income you can use. Know your net number, not your gross.
• A high debt-to-income ratio. Variable income already gets discounted; piling on car and card payments narrows your approval further. Clearing balances first can help, as our breakdown of which debts to pay off before buying lays out.

The buyers who sail through are the ones who talk to a lender early, pull their own W-2s and stubs, and ask for the qualifying income figure in writing before house-hunting. That single number, not your gross pay, is what you can actually spend.

The bottom line

If a chunk of your pay swings, your qualifying income is a calculated, averaged number that will almost always sit below your gross. That isn't a trick; it's the lender making sure the payment survives a normal year, not just a great one. Learn your averaged figure early, keep your documentation clean, and budget from that number rather than your peak. Do that, and variable income becomes a strength that gets you into a home you can comfortably keep, instead of a stretch that tightens every time commissions dip.
