Triple Discount Calculator

What is a triple discount?

A triple discount applies three consecutive percentage markdowns to an original price. Each discount reduces the current price, not the starting sticker price. Retailers often stack promotions this way during clearance events.

For a single markdown, use the discount calculator. To find the sale price after one percentage off, try the sale price calculator.

Sequential discount formula

Where $P_0$ is the original price, $d_1$, $d_2$, and $d_3$ are the three discount rates, and $P_f$ is the final price. Total savings equals $P_0 - P_f$.

Worked example

Start with a $100 item and apply 20%, then 10%, then 5% off in order. After 20% the price is $80. After 10% it is $72. After 5% the final price is $68.40. Total savings are $31.60, which is an effective 31.6% discount from the original $100.

Why stacked discounts differ from adding percentages

Three discounts of 20%, 10%, and 5% do not equal 35% off the original price. Because each markdown applies to a smaller base, the effective discount is 31.6%, not 35%. Always multiply the remaining price factors rather than summing the rates.
