YTD Income Calculator

Your pay stub prints a year-to-date figure every payday, but it does not tell you what that pace means for the full year. This calculator takes your YTD gross (or builds it from your salary or your hourly rate and hours), adds overtime and bonuses, turns your YTD deductions into an effective rate, and projects your annual gross and net to December 31 using the exact number of days elapsed.

Quick Answer

How the calculator builds your YTD gross

There are three routes to a gross figure, and the calculator tries them in a fixed order. Knowing the order matters, because it decides which of your numbers is actually in charge.

1. Your stub figure (wins over everything). If YTD gross has any positive value, that is the base. This is the right route whenever you have a recent pay stub.
2. Salary spread. For the Salaried type with gross blank, base pay is estimated as annual salary divided by days in the year, times days elapsed. A $78,000 salary at July 1, 2026 (day 181) estimates $38,679 of base gross, and the projection hands the full $78,000 back, as it should.
3. Rate times hours. For Hourly, Part-time and Seasonal types with gross blank, base pay is hourly rate times hours worked YTD. At $25 an hour and 1,040 hours, that is $26,000.

Whichever route supplies the base, overtime and bonuses are then added, and the total is what gets projected. Two gaps in this logic are worth knowing before you rely on it. Commissioned and contractor types get no estimate at all: the salary field stays on screen for them, but the estimate never reads it, so those workers must type the stub figure. And if you started mid-year, remember your stub’s YTD covers only this employer: add earlier employers’ totals into the gross field yourself if you want a true calendar-year picture. Workers checking a single rate against time can cross-check with the annual income to hourly calculator, and anyone annualizing for a loan application should also read the section on pay-period methods below, because lenders rarely use day counts.

The formula: a day-count straight line

Every headline figure comes from counting days between your two dates and scaling by them. The full chain is:

Remaining income is the projection minus what you have already earned, floored at zero. The deduction side is just as plain: the effective rate is total YTD deductions divided by total YTD gross, and projected annual net is projected gross times one minus that rate. Payroll systems annualize wages for withholding in a related way (see IRS Publication 15, the Employer’s Tax Guide), which is why the net figure is labelled an estimate: real withholding is bracketed and lumpy, not a flat rate. For a single paycheck’s gross-to-net detail rather than a year view, the bonus payment calculator handles the one-off payment case, including the supplemental withholding rate.

Worked example: a July 2 pay stub, checked line by line

Enter the defaults above and press Calculate YTD Income to reproduce every figure. The stub: salaried, $60,000 salary on file, YTD base gross $30,000, overtime $2,000, bonus $1,000, and deductions of $4,200 federal, $1,320 state, $2,046 Social Security, $478.50 Medicare and $660 other, with stub net pay of $24,295.50.

One consistency check worth doing on your own stub: the net pay field. Here $33,000 minus $8,704.50 of deductions is exactly the $24,295.50 net printed on the stub, which confirms the deduction lines were copied completely. If your check fails, a deduction line is usually missing from the stub copy, most often a retirement contribution sitting in the “other” bucket. Note the calculator itself never performs that subtraction for you: net pay is echoed in the breakdown for this manual check, and nothing else.

Three ways to annualize YTD, and when each one wins

This calculator uses the days method; it is not the only legitimate one. The weeks method divides by weeks elapsed and multiplies by 52, which suits weekly-paid workers whose income genuinely arrives in week-sized chunks. The pay-period method divides by paychecks received and multiplies by paychecks per year: 52 weekly, 26 biweekly, 24 semimonthly, 12 monthly. Lenders verifying income usually ask for the pay-period version, because it matches how payroll actually disburses salary, and mortgage underwriters pair it with the figures on your final stub of the year.

The trap inside the pay-period method is the biweekly count. Biweekly means every two weeks, which is 26 paychecks, not 24: twice a month (semimonthly) is the 24 figure. Annualize a biweekly worker with 24 and you erase two full paychecks, roughly a month of pay, from the year. Day counts sidestep the trap entirely, which is one reason this tool counts days. The sibling question, turning an annual figure into a monthly budget number, is what the annual income to monthly calculator is for; and if you only need to price a block of hours, the hours to money calculator does that one conversion without the year framing.

The Social Security wage base behind the insights

Social Security tax stops once your wages pass an annual cap; Medicare tax never does. The cap, the taxable wage base, is set by the Social Security Administration each year, and the calculator checks your projection against the base for the tax year you select, using the table built into the tool:

The figures match the Social Security Administration’s published maximum taxable earnings by year, with the year-by-year series also tracked on the SSA’s contribution and benefit base page. Two honest limits: the tool’s table stops at 2026 and silently uses the 2026 base for any other tax year, and the withholding rates behind the stub lines are the standard employee rates in IRS Topic No. 751 (6.2% Social Security, 1.45% Medicare). If your projection clears the base, expect Social Security withholding to stop in later paychecks while Medicare continues, which also means your effective deduction rate will drift down over the rest of the year.

The fine print: fields and insights with narrow jobs

Three behaviours of this tool are easy to misread, so they are stated plainly here rather than discovered by accident. First, the insights panel talks about pace, but its pace lines are driven by how much of the year has passed, not by any comparison with a target salary: past roughly 60% of the year the panel calls any run “above pace” on the strength of the calendar alone, and the “below pace” branch in the code can never trigger, because the figure it tests is the calendar fraction itself. Treat the insights as prompts, not verdicts. Second, the projection spreads one-off income across the whole year: a $10,000 bonus paid in March is projected as if bonuses arrive at that rate all year, which overstates a normal year’s total. For a conservative read, run the calculator once with the bonus included and once without. Third, the inputs accept whatever you type, including negative amounts, which are subtracted: useful for correcting an overstated line, dangerous as a typo. Seasonal work bends the straight line hardest of all, since the method assumes the daily average so far repeats; the U.S. Department of Labor overtime page is the reference for how the overtime lines feeding this tool are supposed to be paid in the first place.

What competing YTD calculators miss

The tools ranking for this keyword each cover part of the job:

• BraveCalculator’s YTD calculator: a clean weeks-based annualizer (YTD divided by weeks worked, times 52) with a worked example. But weeks are a coarse unit mid-month, it takes no deductions at all, and there is no net picture.
• Hunter Galloway’s YTD calculator (Australia): the strongest day-count treatment found, with an explicit inclusive-day formula and a worked example showing why doubling a half-year figure is wrong. It is built for the Australian July-to-June financial year and payslip rules, and it stops at gross: no deduction rate, no projected net.
• Savvy Calculator’s year-to-date paycheck tools: good per-paycheck gross-to-net math with assumed tax rates. The framing is one paycheck extended, not a stub reconciled: it never asks what you have actually had withheld so far.
• OwnCalculator’s W-2 tools: deduction breakdowns from W-2 boxes, useful at filing time in January, but they look backward at a finished year and never project the current one.
• The gap this page fills: your actual stub reconciled in one run: base, overtime and bonuses separated, your real withheld amounts turned into an effective rate you can reuse for budgeting, a projected net labelled as the estimate it is, and a wage-base check against the correct year, with the tool’s own limits (the commissioned estimate gap, the display-only net field, the calendar-driven pace lines) disclosed on the page instead of buried.
