What this calculator does

This simple tool converts a percent-off discount into the exact amount you save and the final price you pay. Enter the original price and the discount percentage; the calculator instantly returns the discount amount, final price, and the percentage you still pay. It also supports copying or sharing the result for easy record-keeping.

Why this is useful

  • Shop smarter: compare sale tags quickly and see real savings rather than guessing.
  • Budgeting: plan purchases and understand how sequential coupons or taxes will affect the final cost.
  • Teaching & testing: great for homework and practice with percentages.

How to use the calculator

  1. Type the Original Price (e.g., 149.99).
  2. Enter the Discount Percent (e.g., 25 for 25% off).
  3. Click Calculate (or press Enter). The tool shows:
    • Discount amount (how many dollars you save),
    • Final price (what you pay), and
    • Percentage paid (100% − discount%).

How it works

  • Discount amount = Original Price × (Discount % / 100)
  • Final price = Original Price − Discount amount
  • Percentage paid = 100 − Discount %

If you know final price and want the discount rate:

  • Discount % = 100 × (Original Price − Final Price) / Original Price.

Quick example

Original price = $200, Discount = 15%

  • Discount amount = $200 × 0.15 = $30
  • Final price = $200 − $30 = $170
  • Percentage paid = 85%

Advanced tips

  • Stacked discounts: If you apply multiple percentage discounts one after another (e.g., 20% then 10%), the second percent applies to the already-reduced price not the original so total savings < simple sum of percentages. (Use the calculator repeatedly for precision.)
  • Including tax: If you want the amount you actually pay at checkout, calculate the final price first and then apply tax on the final price (Final × (1 + taxRate/100)).
  • Reverse lookup: When a seller advertises a percentage but shows only sale price, use the reverse formula above to verify the actual discount.

Parameter explained

  • Original Price: The product’s full price before any discount. Enter a positive number (decimals allowed).
  • Discount Percent: The percentage off the original price (0–100). Enter 25 for 25% off.

FAQ

Q.1 What if discount > 100%?

A: That’s invalid the calculator prevents it. Discounts above 100% would imply negative final prices.

Q.2 How do I compare two discounts?

A: Calculate each final price separately and compare dollar savings or final price values.
