Professional Discount Calculator
Calculate discounts with precision
Features
- Discounted price from original price and percentage off
- Savings amount computed alongside the final price
- Multi-step discount stacking (apply a second percentage on the discounted price)
- Works with any currency — values are unitless
- Everything runs in your browser
Tips & Best Practices
- Final price = original × (1 − discount/100); savings = original − final.
- Stacking discounts multiply: 20% off then 10% off is NOT 30% off — it's 28% off (0.80 × 0.90 = 0.72).
- Discount values above 100% would give a negative final price; the input doesn't clamp, so check before sharing the result.
- No tax handling — apply tax to the discounted price separately if your jurisdiction requires it.
- Pre-tax vs. post-tax discounts give the same final price; only the labelled "savings" line differs.
