How this instrument works
Annual income, in the sense most forms mean it, is not a single paycheck line — it's every recurring dollar a person earns in a year added together: base salary, bonus or commission, and anything else that shows up regularly outside a main paycheck. The formula stays a plain sum on purpose. A mortgage application, a rental screening, or a scholarship's income-eligibility test doesn't care which stream a dollar came from; it asks for the combined total, and a straight addition is the honest way to answer that question without smuggling in a judgment about which income counts more.
That plainness hides a real gap. Someone who reports only their base salary on a form asking for annual income understates what they actually earn whenever a bonus or side project adds real money on top — and the difference is rarely trivial. A $65,000 base salary with a $5,000 bonus and $2,000 of side income is a $72,000 combined total, roughly eleven percent above the base figure alone, which is enough to change whether an income threshold like a landlord's 3x-rent rule clears or fails on a given unit.
The total this instrument returns is gross, before tax, and it is a ceiling, not a guarantee. Underwriters and landlords frequently discount irregular income: a bonus or freelance stream often needs two years of documented history before it's counted in full, and some lenders credit only a fraction of it. Treat the sum here as the honest combined figure you'd write on an application, then expect whoever reviews it to apply their own, stricter test to the bonus and other-income pieces.
- Enter your yearly pay before tax into Base salary, $ — the figure from an offer letter, W-2, or a pay stub annualized out to twelve months.
- Enter the bonus or commission you actually received, or reasonably expect, into Annual bonus, $.
- Add freelance work, rental income, dividends, or any other recurring source into Other income (side work, investments), $.
- Read Total annual income — the instrument adds all three fields with no discount applied, at face value.
- Swap in a different bonus or side-income figure to see how a raise, a slow bonus year, or a new side project moves the total.
Worked example — $65,000 salary, $5,000 bonus, $2,000 other
Set Base salary, $ to 65,000, Annual bonus, $ to 5,000, and Other income (side work, investments), $ to 2,000 — a salaried employee with a modest year-end bonus and a small side project. The instrument adds all three straight through and returns a Total annual income of exactly $72,000, with no field weighted more heavily than another.
That $72,000 figure, not the $65,000 base salary alone, is what a mortgage application, a rental screening, or an income-based aid form is really asking for when it says annual income — the two numbers differ by nearly eleven percent here, enough to move a 3x-rent test on a $1,900 unit from failing to passing. A lender reviewing that same bonus may still ask for two years of pay stubs before counting it in full, so treat this total as the honest sum, not a guaranteed approval figure.
Questions
Why not just report my base salary as my annual income?
Because most forms that ask for annual income mean every recurring dollar, not just base pay. Bonus, commission, freelance earnings, and investment income all count toward the figure a lender, landlord, or aid program is really evaluating — leaving them out understates what you earn and can cause an income test like 3x rent to fail when the true total would have passed.
Should Annual bonus, $ hold last year's bonus or this year's expected one?
Use whichever figure the form or lender asks for — usually last year's actual bonus, since it's verifiable on a pay stub or W-2. Many underwriters average two years of bonus history rather than counting a single year's figure in full, so a one-year total from this instrument is a starting point, not the exact number a lender will credit.
What counts as Other income (side work, investments), $?
Any recurring money outside a regular paycheck: freelance or gig income, rental income, dividends and interest, alimony received, or a side business's net profit. One-off windfalls like a tax refund or a gift don't belong here — they aren't income a lender or landlord can count on repeating next year.
Is Total annual income the same as taxable income?
No. This total is gross income before any tax, deduction, or adjustment is subtracted — the same starting figure the IRS treats as gross income before adjustments and further subtractions turn it into taxable income. Use this sum as the first input to those later calculations, not as a substitute for them.
Will a lender count all of my bonus and side income?
Often not in full. Many mortgage underwriters require two years of documented history before counting bonus, commission, or self-employment income, and some discount irregular income by a set percentage. This instrument adds every dollar you enter at face value; a lender's own worksheet may credit less.
Does this total include a spouse's or co-applicant's income?
Only if you enter it. Add a second earner's salary, bonus, and other income into the same three fields — Base salary, $, Annual bonus, $, and Other income (side work, investments), $ — to get a combined household total, or run the instrument twice to compare each applicant's figure separately.
