How to use

  1. Enter the original price in the first field (e.g. 79.99). Use your local decimal separator.
  2. Choose “Discount (%)” or “Discount amount” using the toggle. Percent mode applies a percentage off; amount mode subtracts a fixed sum.
  3. In percent mode: enter the discount percentage (e.g. 25 for 25% off). The discount cannot exceed 100%.
  4. In amount mode: enter the dollar (or currency) amount to subtract (e.g. 20 for $20 off). The amount cannot exceed the original price.
  5. The tool shows “You save” (the discount) and “Final price” (what you pay). Results update as you type.
  6. Use percent for “X% off” sales and amount for “$Y off” or coupon values.
  7. Currency formatting is for display only; enter numbers without symbols.

FAQ

Can I use a fixed amount instead of a percent?
Yes. Switch the control to “Discount amount” and enter the exact amount to subtract (e.g. 20 for twenty dollars off).
Why does it show an error?
In percent mode, the discount cannot exceed 100%. In amount mode, the discount cannot exceed the original price. Check both values.
Does it include tax?
No. The result is the price before tax. Tax is usually applied to the final sale price; calculate that separately if needed.
What if I have multiple discounts?
This tool does one discount at a time. For stacked discounts, apply the first, then use the result as the new “original price” for the second.
Which decimal separator can I use?
Use a period or comma; both are accepted. The displayed currency format may follow your locale.
Is the result rounded?
Final values are shown with normal currency rounding (typically two decimal places). The underlying maths use full precision.
Can I use it for any currency?
Yes. Enter numbers only (no currency symbols). The tool doesn’t convert between currencies; it only does the discount maths.
Is this financial or tax advice?
No. It’s a general-purpose calculator. For business or tax purposes, verify with your accountant or software.
