Michigan Variable Income Calculator

Michigan Variable Income Calculator — Will Your Overtime, Bonus & Commission Count?

The short answer: lenders can count overtime, bonus, and commission — usually as a two-year average — as long as the history and trend support it. Many borrowers get quoted on base pay alone and wrongly conclude they can’t afford a home. This variable income calculator shows how much of that extra income is actually usable, so you don’t leave qualifying power on the table. It layers the usable share of your overtime, bonus, and commission on top of your base pay, applies the conservative lower-year read when the trend is declining, and translates the total into the loan amount that income can support.

My name is Edward Kalavitz, creator of this variable income calculator. As a dual-licensed Michigan Realtor and Mortgage Loan Originator, I see hourly and incentive earners underestimate themselves constantly — the bank’s first quote is rarely the whole story.

How the Variable Income Calculator Works

The variable income calculator follows the method a lender uses: it takes the two years of overtime, bonus, or commission you enter, computes a 24-month average, and expresses it as a monthly figure. If the most recent year is lower than the prior year, the variable income calculator switches to the conservative read — the lower, most recent year — because a declining trend gets the cautious treatment. Then it checks your history length, since income you haven’t earned long enough generally can’t be counted yet.

That mirrors how underwriting thinks about variable income: history, consistency, and the likelihood it continues. The variable income calculator can’t see your paystubs, so treat the result as a strong estimate — then let me confirm the exact usable figure from your documents.

How Many Years of History You Need

For overtime and bonus, lenders generally want a two-year history of receiving the income before they’ll count it; the variable income calculator averages those two years. With one to two years, some programs will still credit it at underwriter discretion if the continuity is strong and well documented. With less than a year, the income usually can’t be used yet — but you may still qualify on base pay now and add it later, which the variable income calculator flags so you can plan the timing.

What Can Disqualify Your Variable Income

A few things keep variable income from counting, and the variable income calculator helps you spot them early. A job change can reset the history, since the new role may not have the track record yet. A declining trend means the lower year is used — or, if it’s falling sharply, it may be excluded. And an inconsistent or sporadic pattern (a big bonus one year, nothing the next) is hard to call “likely to continue.” None of these are automatic dealbreakers; they just mean the variable income calculator’s estimate needs a closer look from a loan officer.

Worked Example: $14,000 + $12,000 of Overtime

An hourly earner had $14,000 of overtime last year and $12,000 the year before, with a 2+ year history. Here is how the variable income calculator reads it:

Because the income is rising, the full 24-month average is used; if it had fallen, the lower recent year would apply. Run your own numbers in the variable income calculator above.

That $1,083 a month of usable overtime is on top of your base pay — and at typical debt ratios it can lift your buying power by tens of thousands of dollars. That’s the qualifying power most hourly earners never realize they have, and exactly what the variable income calculator is built to surface.
