Bought in a heatwave, when nobody haggles.

Bought in a heatwave, at the worst possible moment to be choosy.

An air conditioner is taxed at the normal rate. Almost nobody buys one calmly. You buy it in the week everyone else is buying one, which is when there is least choice and least reason for anyone to give you a deal. Then the real cost turns up quietly on the electricity bill, every summer, for years.

Air conditioners carry the standard sales tax. They are bought under the same pressure as a failed appliance, except worse: demand spikes exactly when everyone else needs one, which is when choice is narrowest and price discipline weakest. The running cost then arrives quietly on the electricity bill for years afterwards.

Jurisdiction applied

  • State: TX
  • Sales tax county: Harris County (Houston)
  • Local income tax: none selected

Assumptions

  • We use the normal sales tax rate.
  • The electricity to run it is left out. Over the life of the unit that usually costs more than the unit did.
  • Sales tax applies at the standard rate.
  • Electricity to run it is excluded and typically exceeds the purchase price over the unit's life.

Your position in the tax system

29.65% on the next dollar

Every 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 51

The 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: $173, from New Hampshire to California.

Where every dollar goes

30% never reaches you

The $769.37 you must earn, followed to where it lands. Select a band to isolate it.

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.

what actually lands

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.
