How much does a coffee habit really cost?
The cup is trivial. The habit is not.
A daily coffee habit isn't a $5.50 decision — it's a decade-long one, and the money you don't spend on it could compound into something much larger.
- Sales tax applies at the standard rate for your county.
- A 15% tip is assumed by default on coffee-shop purchases — edit if you brew at home.
- The compounding comparison assumes the money not spent is invested at the long-run market return, not left in cash.

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.
Same purchase, different state
TX is #7 of 51Only income tax and sales tax move — the sticker price is held constant, so this is the part of the cost your address actually controls. Spread across all 51: $6,114, from New Hampshire to California.

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.
Where this differs most
States whose answer is genuinely different from the national picture — either near the top or bottom of the range, or structurally unusual. States that land mid-pack are covered by the figures above.
