How this calculator works
Sequential discounts multiply the remaining price. The second percentage applies to the already discounted price, not the original amount. The effective discount reports the combined saving as a share of the original price. Taxes and delivery charges are excluded.
The formula
Final price = Original price × (1 − d1/100) × (1 − d2/100)
Amount saved = Original price − Final price.A quick example
A 100 item discounted by 20% and then 10% costs 72. The total saving is 28, so the combined discount is 28%, not 30%.
How to use this calculator
- Enter the original price.
- Enter the first discount and optional additional percentage.
- Calculate the final price and total saving.
A few common questions
Do two discounts simply add?
No. Each successive percentage is applied to the remaining price.
Can I enter 100%?
Yes. A 100% discount reduces the price to zero.
Are taxes included?
No. Apply any relevant tax separately to the appropriate taxable amount.
