You buy them to avoid paying someone. That is worth checking.
Bought to avoid paying someone else, and almost never measured against what that would have cost.
Tools get the normal sales tax. At $400 that is not much. The real question is the one people skip: the tools were bought to avoid paying a tradesperson, so the fair comparison is against what that job would have cost — and against the hours you will spend doing it.
Tools carry the standard sales tax in every state that levies one. The purchase is usually framed as a saving against hiring a tradesperson, which makes the honest comparison not tool-versus-nothing but tool-versus-the-job — including the hours the work will actually take.

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 51The purchase inputs and income stay the same. Your row uses your calculator settings; other states use example counties and omit local income tax. Spread across all 51: $139, from New Hampshire to California.

Where every dollar goes
30% never reaches youThe $615.49 you must earn, followed to where it lands. Select a band to isolate it.

- Power tools$400.00
- Sales tax$33.00
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.
