Single filer on $75,000 in Harris County, Texas. Your calculator below uses your settings.
The price tag is only about half the real story.
The sticker price is roughly half of what the car costs you.
The price on the windshield isn't what the car costs you. Add the income tax you paid to earn that money. Add sales tax. Add interest if you financed it. Then add five years of insurance, upkeep, and gas. Together those come to far more than the sticker price itself — the number below works out exactly how much, for your state and your salary.
Between the income tax you paid to earn the purchase price, sales tax, financing interest, and five years of insurance, maintenance, and fuel, the car you 'paid $40,000 for' costs far more than its sticker price in pre-tax income — the figure below works out how much, for your own state and salary.
- We work out insurance, upkeep, and gas over five years using national averages. Your own costs depend on your state, your car, and how much you drive.Ownership costs (insurance, maintenance, fuel) are modeled over a five-year holding period using national averages — your actual costs will vary by state, driving habits, and vehicle.
- Interest and 'what the money could have earned instead' are shown separately. We never add them together into one number, because that would count the same thing twice.Financing interest and opportunity cost are both shown as separate 'cost of capital' framings — never summed together into one headline number.
- We subtract what the car should still be worth when you sell it, so you're not charged for the whole price twice over.Depreciation is net of an assumed resale value at the end of the holding period, not the full purchase price.
- Sales tax uses the standard rate for your county, applied to the purchase price.Sales tax applies at the standard rate for your county on the purchase price.

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 #1 of 30The 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 30: $21,863, from Texas 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.

Questions people ask
Why do I have to earn more than the price?
You buy with take-home and you earn in gross. The gap between them is tax, which is why the salary a purchase demands is always more than the purchase costs.
Why is the total more than the price I was quoted?
Fees close the gap. They are charges rather than taxes, they go to the seller or an intermediary, and they are unavoidable, which is why the total counts them.
Why count money I was going to spend anyway?
Because spending it is a choice about where it goes, not whether it exists. Money kept would have earned something over the years, and that forgone growth is a real part of what the purchase cost — invisible on the receipt, but not zero.
Is the purchase price the end of it?
Buying is one payment; owning is a stream of them. This page counts both, because the second is usually the larger.
Why does required gross income exceed the purchase price?
Required gross income is the outlay divided by one minus the combined marginal rate applying to the incremental income — federal, FICA and any state or local layer. The excess over the nominal price is the marginal wedge, not a fee, and it rises with the buyer's marginal rate rather than with the price.
What non-tax charges are included in this total?
The total includes mandatory non-tax charges levied by the seller or an intermediary. These are not remitted to a taxing authority and are not deductible as tax, but they are a condition of the transaction, so excluding them would understate the cash outlay while appearing exact.
What justifies including forgone investment return in a cost figure?
Opportunity cost is the return forgone by consuming rather than investing the same sum over the modeled horizon. It is an economic cost rather than a cash outlay, so it is reported separately from cash totals and never added to them silently. ⚠️ It depends on an assumed rate of return and is the most assumption-sensitive figure on the page.
What ongoing costs follow this purchase?
Total cost of ownership includes recurring maintenance, insurance, consumables and replacement over the modeled holding period, discounted where applicable. For durable goods this component frequently exceeds acquisition cost, so a purchase-price-only comparison systematically favors cheaper items with higher running costs.
