🏷️ Discount Calculator
🔒 Sicher & Clientseitig
Enter an original price and a discount percent — the calculator returns the final price and the dollar (or won) amount you save. Optional second discount for stacked sales (e.g., "30% off, then extra 20% at checkout").
How to use
- Enter the original (full) price.
- Enter the first discount percent.
- Optional: enter a second discount that applies after the first (typical "extra X% at checkout").
- Click Calculate. Final price + savings + effective combined discount appear.
Stacked discounts don't add. A 30% then 20% discount is not 50% — it's 1 − (0.7 × 0.8) = 44%. The effective discount field shows the combined rate.
