How it works
How it works
Each discount applies to the price left after the one before it, so the price is multiplied by (1 - discount) for each step. The effective discount is the total savings divided by the starting price.
FAQ
About this calculator
Why is 20% plus 10% not 30%?
Because the second discount applies to the already reduced price, which is a smaller base.
Does the order matter?
Not for percentage discounts. The final price is the same in any order. It can matter if one discount is a fixed dollar amount.
Is sales tax included?
No. Tax is usually figured on the price after discounts, but rules vary.
Is anything saved?
No. The math runs in your browser and nothing you enter is sent to us.
Is this a quote or advice?
No. It is a calculator for general information. Check results against your own figures before you rely on them.
