Breakdown
Plain arithmetic on the price and discount you enter; sales tax, if added, is applied to the discounted price. An estimate of a checkout total, not financial advice.
About this calculator
A free discount calculator that turns an original price and a discount into the sale price and the amount you save. It handles both percent-off and fixed dollar-off discounts, reports the effective percentage either way, and can add sales tax to the discounted price for a true checkout total. It is plain arithmetic, computed in your browser — an estimate of what you will pay, not financial advice. Discounts are clamped so a price can never go below zero.
Percent off versus amount off
A percent-off discount scales with the price: 25% off a $80 item saves $20, but 25% off a $200 item saves $50. A fixed amount-off discount takes the same dollars off regardless of price — $20 off is $20 whether the item is $80 or $200. The calculator supports both and always reports the effective percentage, so you can compare a "$15 off" coupon against a "20% off" sale on the same item and see which actually wins.
That comparison is where shoppers most often lose money. On a cheap item a flat dollar coupon can beat a percentage; on an expensive item the percentage usually pulls ahead. Reading the effective percent-off figure for each removes the guesswork.
Adding tax for the real total
The sticker discount is not what you pay at the register. Sales tax is applied to the discounted price, not the original, so the order matters: discount first, then tax. The optional tax field does exactly that and shows the final, tax-inclusive total alongside the pre-tax sale price.
Treat the result as a close estimate. Real receipts can differ slightly because of rounding rules, item-level tax exemptions, or discounts that apply to subtotals rather than individual items, but for everyday shopping the figure is accurate to the cent on the inputs you give it.

Questions
- Is the discount calculator free?
- Yes. It is free, needs no account, and calculates in your browser; nothing you enter is uploaded or stored.
- How do I calculate a percentage discount?
- Multiply the original price by the percent off divided by 100 to get the savings, then subtract that from the price. The calculator does this and also shows the sale price and tax-inclusive total.
- Is tax applied before or after the discount?
- After. Sales tax is calculated on the discounted price, so the calculator applies the discount first and then adds tax to the reduced amount.
- Can a discount make the price negative?
- No. A fixed amount-off discount larger than the price is capped at the price itself, so the sale price bottoms out at zero rather than going negative.
