Über Rabatt-Rechner

Need the sale price from a percent off, the percent from two prices, or the original from a discounted total? This calculator solves any missing value among original price, discount %, and final price, and shows savings. Stack mode applies discounts in order (e.g. 20% then 10%) and reports the effective rate — which is not the same as adding the percents. Everything runs in your browser. ⚠️ Ignores taxes, store rounding, and coupon fine print. Educational estimates only — not financial, investment, or tax advice.

So funktioniert's

  1. Choose a mode (original+%, original+final, %+final, or stack)
  2. Enter the known values (comma-separated list for stack)
  3. Read final price, discount %, and savings

FAQ

Do stacked discounts add?

No — they multiply in sequence. Example: 100 with 20% then 10% → 80 then 72; effective discount is 28%, not 30%.

Can I solve for the original price?

Yes — use the “% + Final” mode. A 100% discount cannot uniquely recover the original price.

What about tax and rounding?

Taxes and store rounding are out of scope — we compute with the decimals you enter.

Is this financial advice?

No. ⚠️ Educational estimates only — not investment or tax advice.

Is my input sent anywhere?

No. All calculation runs in your browser.
