YTD Calculator — Project Your Year From a Pay Stub

Year to date is the cumulative total since 1 January. Your stub carries a YTD column alongside the current pay period, and every line has one: gross pay, each tax, each deduction, and net pay.

The distinction that matters before you project anything is gross versus net. YTD gross is the figure before deductions and the one lenders, landlords and benefit programmes ask for. YTD net is what reached your bank. Projecting from net when someone asked for gross understates your income by 20–30%.

The YTD lines worth checking

• YTD gross — total earnings before anything comes out
• YTD federal tax — compare against projected annual liability to catch a W-4 problem early
• YTD Social Security — stops once wages reach the $184,500 wage base for 2026; Medicare keeps going
• YTD pre-tax deductions — 401(k), health premiums and HSA contributions, useful for tracking against annual limits

Two steps. Divide YTD gross by pay periods already paid to get an average per period, then multiply by the periods in a full year.

Counting the periods is where it goes wrong. Use the number of cheques actually received, not the calendar month. Someone paid biweekly in mid-July has usually had 14 or 15 cheques, not 13 — biweekly pay produces 26 a year, so two months contain three pay dates rather than two.

The projection assumes the rest of the year resembles the part already paid. That assumption breaks for anyone with seasonal overtime, quarterly commission, an end-of-year bonus, or a raise that landed partway through. It is exactly why underwriters ask for two years of W-2s alongside the stub rather than trusting the annualised figure on its own.

Is your withholding on track? Project the year, work out the tax on that income, and compare with YTD federal tax scaled up the same way. A large refund means you have lent the government money interest-free; a large balance due means a penalty risk. Either way a new W-4 fixes it, and doing it in summer spreads the correction over more remaining cheques than doing it in November.

Will you hit the 401(k) limit? Divide YTD contributions by periods paid and project forward. Hitting the annual cap early stops your contributions — and with them any employer match on later cheques, unless your plan trues up at year end.

Have you passed the Social Security wage base? Once YTD wages exceed $184,500, the 6.2% stops and your take-home rises for the rest of the year. Worth knowing before you mistake it for a payroll error.
