Savings = price × discount / 100. A second discount applies to the already-discounted price — stacked discounts multiply, they do not add — and tax is charged after the discounts.
See the final price and exactly how much you save before you buy — with an optional second stacked discount, sales tax added after the discounts, and a reverse check that works out the effective discount from the price you actually paid. Free and instant.

A price of 100 with a 20% discount gives savings of 20 and a final price of 80, before any tax. Stacking a second discount of 10% takes it to 72 — a combined 28% off, not 30% — and typing in the price you actually paid works the effective discount back out in reverse.

It is a visual aid, not a replacement for the numeric output. Some charts compare values with different units, and those magnitudes are not directly comparable.
Check units, signs, assumptions and rounding first. The tool cannot know whether the values you enter describe the real situation correctly.
