Good to know
The multiple discount calculator applies several discounts one after another directly in your browser, in the order shown from top to bottom. Percentage and fixed-amount discounts can be mixed; the tool shows both the effective total discount and how much it differs from simply adding the individual discounts.
Calculation runs locally in the browser. Important: multiple discounts are applied one after another, not simply added — 20% and 10% in sequence don't equal 30%, but around 28%. The order of steps affects the result when mixing discount types.
Typical use cases
Add a promo code to an existing discount
Enter an existing discount and an additional promo code to see the actual final price after both discounts.
Determine the effective total discount for tiered discounts
Enter all discount tiers to see the actual total discount, instead of incorrectly adding the individual percentages.
Tips for better results
Watch the order with mixed discount types
Whether a fixed-amount discount is applied before or after a percentage discount changes the result — reorder steps with the arrow buttons if needed.
Choose the rounding mode based on context
Round after each step if a checkout system does the same, or only at the end for a mathematically more precise result.
