How much do groceries really cost, after tax and after-tax income?
Most states don't tax your groceries — but your income was taxed to earn the money that bought them.
Groceries are exempt from sales tax in most states, but the gross-up is still real: every dollar in your grocery bill is a dollar you had to earn after federal, FICA, and (in most states) state income tax first.
- Sales tax applies only if your state and category (grocery) combination isn't exempt — most states exempt groceries entirely, but not all (see the state comparison).
- This models unprepared, at-home food only — restaurant and prepared food is taxed differently (see the Fast Food Meal category).

Prices and wages are held at today's levels, and the return above is inflation-adjusted to match — consistent by design. The invested-instead line assumes the cash is contributed at the end of each year and left alone; it is an alternative use of the same money, never an extra cost on top.
Your position in the tax system
29.65% on the next dollarEvery extra dollar you earn is taxed at your marginal rate, not your average one — which is why a purchase costs more to fund than a paycheck stub suggests.
Marginal rates are read in gross-income terms: below the standard deduction an extra dollar of pay adds nothing to taxable income, so the true rate there is 0%, not the lowest bracket's. Excludes pre-tax deductions (401(k), HSA), which would lower all three.

Each tax layer is the extra tax this purchase causes — that layer's tax at your income subtracted from its tax at your income plus the gross-up — so bracket boundaries the purchase straddles are handled correctly rather than smoothed over with an average rate.
Is a raise actually a raise?
you keep 70%A raise arrives on top of everything you already earn, so it is taxed at your marginal rate — not the average rate on your whole salary.
Federal, FICA, state and any local income tax — no pre-tax deductions, benefit changes, or payroll withholding quirks, all of which move the real figure. Moving into a higher bracket never taxes the income below the threshold: only the dollars above it pay the higher rate.
