Successive Discount Calculator
A 20% plus 10% offer is not 30% off — each discount applies on the already reduced price. Enter up to three discounts to see the final price and the true effective saving.
How to use
- Fill in the fields above with your own figures — results update live as you type.
- Each discount applies on the already reduced price, one after another — never on the original price again.
- Check the result box and adjust any rate or parameter to test other cases.
Note: A 20 percent plus 10 percent offer is really 28 percent off, not 30 percent. That gap is exactly what this tool shows.
Frequently Asked Questions (FAQ)
What does this calculator find?
The final price and the true effective discount when two or three discounts apply one after another.
Why not just add the discount percentages?
Successive discounts multiply rather than add, so 20 percent followed by 10 percent equals 28 percent off, not 30 percent.
What inputs does the discount calculator need?
The original price and up to three discount percentages. Leave the third discount at 0 if it does not apply.
What is the effective discount?
The single percentage that gives the same final price as all the discounts combined — it is shown so you can see the real saving.
