Discount Calculator
Compute the final price after one or more percentage discounts. Add stacked coupons (each applied to the already-discounted price) or merge them into a single combined discount — perfect for sale events where you have a 20%-off-everything coupon plus an extra 10% at checkout.
How to use
- 1
Enter the original price
Type the sticker price before any discount. Decimals and thousands separators are accepted.
- 2
Choose stacked vs combined
Stacked applies each discount to the already-reduced price (e.g. 20% then 10% → 28% effective). Combined simply adds the percentages.
- 3
Add your discount tiers
Start with one tier — add up to six. Each tier is a percentage between 0 and 100.
- 4

Common use cases
- Stack a store-wide 20%-off coupon with a 10%-off newsletter code at checkout.
- Compare a 30%-off single discount vs 20% + 15% stacked to see which is better.
- Quickly work out the final price of a Black-Friday deal with multiple layered offers.
- Plan a clearance promotion by modelling different tier combinations.
Limitations
- This calculator produces an estimate only and is not professional financial, tax or investment advice. Always confirm the underlying formulae with your accountant, bank or financial advisor before making decisions.
- Each tier is clamped to 0–100%. A tier over 100% would imply a negative price and is rejected.
- The calculator models percentage discounts only — buy-one-get-one, fixed-amount and conditional offers are not supported.
- Cent-level rounding is applied by your payment processor at checkout; this tool shows the unrounded result.
