Discount Calculator

What is a Discount Calculator?

This calculator takes an original price and a discount percentage, then instantly shows you the sale price and the exact amount you save. No mental math needed while standing in a store aisle.

How to Calculate Discounts

  1. Enter the Original Price — the full price before the discount
  2. Enter the Discount Rate (%) — the percentage off (e.g., 25 for 25% off)
  3. Results appear instantly:
ResultWhat it shows
Discounted PriceThe final price you actually pay
Amount SavedHow much money the discount saves you

Good Examples

Example 1: Seasonal Clothing Sale

A jacket originally costs $120 and is marked 30% off.

  • Original Price: 120
  • Discount Rate: 30
  • Discounted Price: $84.00
  • Amount Saved: $36.00

Example 2: Online Coupon Code

You have a 15% coupon for a $200 online order.

  • Original Price: 200
  • Discount Rate: 15
  • Discounted Price: $170.00
  • Amount Saved: $30.00

Example 3: Black Friday Electronics

A laptop originally priced at $1,200 is 35% off.

  • Original Price: 1200
  • Discount Rate: 35
  • Discounted Price: $780.00
  • Amount Saved: $420.00

Example 4: Grocery Store Deal

A $6.50 item is marked down 20%.

  • Original Price: 6.50
  • Discount Rate: 20
  • Discounted Price: $5.20
  • Amount Saved: $1.30

Understanding Double Discounts

When stores offer “an extra percentage off the sale price,” the two discounts are not additive.

Example: A $200 coat is 30% off, plus an extra 20% off coupon.

StepCalculationPrice
Original$200
First discount (30%)200×0.30=200 × 0.30 = 60 off$140
Second discount (20%)140×0.20=140 × 0.20 = 28 off$112
Total saved$88 (44%, not 50%)

The second discount applies to the already-reduced price, not the original. So 30% + 20% = 44% total, not 50%.

Smart Shopping Tips

Compare actual savings, not just percentages. A 50% discount on a 10itemsaves10 item saves 5. A 20% discount on a 200itemsaves200 item saves 40. The bigger percentage isn’t always the bigger saving.

Watch for inflated “original” prices. Some retailers raise the listed price before a sale to make the discount look bigger. Compare prices across stores before assuming a deal is genuine.

Consider the price per unit. A “Buy 2 Get 1 Free” deal on $30 items is effectively 33% off per item. Compare this to a straight 25% off to see which is actually cheaper.

Formula

Amount Saved:

Amount Saved=Original Price×Discount Rate100\text{Amount Saved} = \text{Original Price} \times \frac{\text{Discount Rate}}{100}

Discounted Price:

Discounted Price=Original PriceAmount Saved\text{Discounted Price} = \text{Original Price} - \text{Amount Saved}

Frequently Asked Questions

Is the discount applied before or after tax?

In most cases, the discount applies to the pre-tax price. Sales tax is then calculated on the discounted amount. Check the store’s policy to be sure.

Can I use this for any currency?

Yes. The formula works with any currency. Enter the price in your local currency — the math is universal.

How do I find the original price from a sale price?

Reverse the formula: Original Price = Sale Price / (1 - Discount Rate / 100). For example, you paid 75aftera2575 after a 25% discount: 75 / 0.75 = $100 was the original price.

Is a bigger discount always a better deal?

Not necessarily. A 70% discount on an overpriced item may still cost more than a 20% discount on a fairly priced alternative. Always compare the final price, not just the discount percentage.
