Quick start
- Open the Percent Off Calculator.
- Enter original price before any discount.
- Use the first example, "Sale plus tax: $80 with 25% off, extra 10% off, and 7.5% tax", if you want to see a filled-out estimate before entering your own values.
- Calculate, read the formula line, then copy the result only after the amounts, percentages, time periods, or assumptions look right.

What this calculator is for
The Percent Off Calculator is for sale and coupon math. It applies the first discount, then applies the second discount to the already-reduced price, which is how stacked percentage discounts usually work.
Good fit examples: Calculate a final sale price. Stack two percent-off discounts correctly.
What to enter
Finance estimates are sensitive to small input changes. Check whether a field expects a monthly amount, annual amount, dollar value, or percent before calculating.
- Enter original price before any discount.
- Enter first discount percent and optional second discount percent as normal percentages.
- Enter sales tax percent only if you want an after-tax total.
Example walkthrough
Try the calculator example: Sale plus tax: $80 with 25% off, extra 10% off, and 7.5% tax. The example result is $58.05 final price, $26.00 saved before tax, 32.5% effective discount.
- $80 with 25% off drops to $60 before any second discount.
- An extra 10% off is then applied to $60, not to the original $80, giving a stronger but not additive discount.
- $100 with 40% off plus another 20% off leaves $48 before tax, so the real discount is 52%, not 60%.
Formula and steps
In plain language: The calculator subtracts the first discount from the original price, applies the optional second discount to that reduced subtotal, then adds tax to the discounted subtotal if a tax rate is entered. For the $80 example, 25% off removes $20 and leaves $60. The extra 10% discount removes $6 from $60, leaving $54. Tax at 7.5% adds $4.05, so the final estimate is $58.05.
If the estimate looks surprising, check the formula and inputs before using the answer in a budget, comparison, or planning note.
How to read the answer
Start with the headline result. Then read the supporting lines to see what made the number larger or smaller, such as rates, time periods, costs, taxes, fees, discounts, or contributions.
- Final price is the amount after discounts and optional tax.
- Savings before tax shows the dollar amount removed from the original price.
- Effective discount shows the real percent saved after stacked discounts.
Common mistakes to avoid
Most bad finance estimates come from mixing rates, terms, monthly amounts, and annual amounts. The other common mistake is using a planning estimate as if it were a final quote.
- Do not add 25% and 10% and assume the discount is exactly 35%.
- Do not forget that tax, shipping, coupon exclusions, minimum spend, and fees can change checkout totals.
- Do not enter 0.25 when the field asks for 25%.

FAQ in plain language
When should I use the Percent Off Calculator?
Use it when you want to test the exact inputs on this page: Calculate a final sale price. Stack two percent-off discounts correctly. The result is a check against your assumptions, not proof that a lender, tax app, broker, platform, or provider will use the same number.
What do the main Percent Off Calculator inputs mean?
Original price means the tag price before the store applies the percent-off discount. Percent off means the first discount rate, entered as 25 for 25%, not 0.25. Extra percent off means an optional second discount applied to the already-reduced subtotal. Tax rate means an optional sales tax rate applied after the discounts, if you want an after-tax estimate.
Do two percent-off discounts add together?
Usually no. A 25% discount followed by an extra 10% discount is not 35% off the original price. The second discount applies to the reduced subtotal, so the $80 example becomes $54 before tax and saves $26, which is a 32.5% effective discount.
Is tax calculated before or after the discount?
This calculator adds tax after the percent-off discounts. That matches many checkout totals, but local tax rules and store systems can vary, especially with coupons, fees, shipping, or special promotions.
What is effective discount?
Effective discount is the real percent saved from the original price after all percent-off discounts are applied. It helps you compare stacked discounts without pretending each percent can be added directly.
Can I use this for coupon stacking?
Use it for one or two percentage coupons. It does not handle fixed-dollar coupons, buy-one-get-one deals, reward credits, minimum-spend rules, or exclusions that remove an item from the promotion.
How do I calculate 40% off plus another 20% off?
Apply 40% off first, then apply 20% to the reduced price. On a $100 item, 40% off leaves $60. Another 20% off removes $12, leaving $48 before tax. The effective discount is 52%, not 60%.
