Stacked Discount
Combine multiple percentage discounts applied in sequence.
About Stacked Discount
Each discount is applied to the already-reduced price, so combined savings are lower than simply adding the percentages. Stores advertise each offer separately, and stacking math shows whether layering rewards actually beats a single big sale.

Assumptions and limits
- The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
