Discount and Tax CalculatorPrice after discount, coupon & sales tax
To get the price after discount and tax, apply the discount first, then add sales tax to the reduced price. Total = Price × (1 − Discount) × (1 + Tax). Example: 30% off $79.99 with 7% tax = $55.99 + $3.92 = $59.91.

How to Calculate the Price After Discount and Tax
Apply the discount first, then add sales tax to the discounted price. Final price = Price × (1 − Discount) × (1 + Tax rate). Example: 30% off $79.99 is $55.99, and 7% tax adds $3.92, so you pay $59.91. Because tax is charged on the lower price, a discount also cuts your tax bill.
Discount and Tax Formula
1 · Discounted price
Sale = Price × (1 − d)$79.99 × 0.70 = $55.99 (rounded to the cent).
2 · Sales tax
Tax = Sale × t$55.99 × 0.07 = $3.92.
3 · Register total
Total = Sale + Tax$55.99 + $3.92 = $59.91.
Does the order matter? For a percentage discount and a percentage tax, no — multiplying in either order gives the same answer. It matters for dollar coupons and manufacturer coupons, explained below.
Store Coupons vs Manufacturer Coupons
A store coupon lowers the price the store charges, so tax is calculated on the reduced price. A manufacturer coupon is reimbursed to the store by the brand, so many states treat it as payment and tax the price before the coupon. Example: a $10 item, a $2 coupon and 8% tax.
| Coupon type | Taxable amount | Tax | You pay |
|---|---|---|---|
| Store coupon ($2 off) | $8.00 | $0.64 | $8.64 |
| Manufacturer coupon ($2 off), taxed pre-coupon | $10.00 | $0.80 | $8.80 |
| No coupon | $10.00 | $0.80 | $10.80 |
Rules vary by state. The calculator lets you switch the manufacturer-coupon treatment on or off.

Common Mistakes With Discount and Tax
Adding tax to the original price
On $79.99 that would add $5.60 of tax instead of $3.92 — overestimating your total.
Subtracting the tax rate from the discount
“30% off minus 7% tax” is not 23% off. Multiply: 0.70 × 1.07 = 0.749, so you pay 74.9% of the tag.
Stacking coupons by adding
Sale plus coupon percentages multiply. Use the Double Discount Calculator.
Using the state rate only
Most states add county or city tax. Use the combined rate from the table or your receipt.
Forgetting the per-item rounding
Registers round each discounted line to the cent before tax, which can shift the total by a cent or two.
Working back from a receipt
To split tax out of a total, divide — don’t subtract a percentage. Use the Reverse Sales Tax Calculator.

Discount and Tax Calculator FAQs
After. Apply the discount first, then add sales tax to the discounted price. 30% off $79.99 is $55.99, plus 7% tax is $59.91.
Multiply the price by (1 − discount) and then by (1 + tax rate). $100 at 20% off with 8% tax: 100 × 0.80 × 1.08 = $86.40.
The sale price is $55.99 and the tax is $3.92, so the total is $59.91.
Yes. Because tax is charged on the price after store discounts, a 30% discount also cuts your tax by roughly 30%.
In many states, yes: sales tax is charged on the price before a manufacturer coupon, because the manufacturer reimburses the store. Store coupons usually reduce the taxable price. Check your state’s rules.
Use the combined rate on a recent receipt, or pick your state’s average combined rate from the dropdown, which uses Tax Foundation data as of July 1, 2026.
Louisiana has the highest average combined rate at about 10.13%, followed by Tennessee (9.61%), Washington (9.57%), Arkansas (9.48%) and Alabama (9.46%), according to the Tax Foundation’s midyear 2026 data.
Delaware, Montana, New Hampshire and Oregon have no state or local sales tax. Alaska has no state sales tax but allows local sales taxes.
No. 30% off with 7% tax is not 23% off. Multiply instead: 0.70 × 1.07 = 0.749, so you pay 74.9% of the tag price.
Divide the total by (1 + tax rate). $59.91 at 7% was $59.91 ÷ 1.07 = $55.99 before tax. The Reverse Sales Tax Calculator does this for any receipt.
In countries where prices already include VAT or GST, the shelf price is final. If tax is added at checkout, enter the VAT or GST rate as the tax rate.
