Percent Off Calculator

TL;DR

Enter the original price and discount percentage — the calculator returns your savings and final price instantly
Stacked discounts (20% off then a 10% coupon) don''t add: they compound sequentially, giving 28% not 30%
To find what percentage off something was, divide savings by the original price and multiply by 100
Works for any currency — the math is identical whether you''re using USD, GBP, EUR, or NZD

The percent off calculator does one thing precisely: tell it the original price and the percentage off, and it tells you how much you save and what you''ll actually pay. No signup wall, no ads interrupting the answer.

How do I calculate percent off a price?

Multiply the original price by the discount as a decimal, then subtract. A $120 item at 25% off: $120 × 0.25 = $30 saved, final price $90.

Formula: final price = original price × (1 − discount rate)

So 30% off $85 is $85 × 0.70 = $59.50.

The calculator does this instantly — but knowing the formula lets you sanity-check any receipt. A "50% off" tag should cut the price exactly in half. If a sticker says $39.99 on something originally $89.99, that''s roughly 56% off, not the 40% the sign might claim.

What happens when two discounts apply at the same time?

They don''t add. This is the single most common shopping math error.

A 20% store discount followed by a 10% coupon on a $100 item:

After 20% off: $100 × 0.80 = $80
After 10% off the reduced price: $80 × 0.90 = $72
Effective discount: 28%, not 30%

Scenario	Calculation	Final Price
20% off + 10% off (sequential)	$100 → $80 → $72	$72.00
Flat 30% off	$100 × 0.70	$70.00
15% off + 15% off (sequential)	$100 → $85 → $72.25	$72.25

To handle stacked discounts with the percent off calculator: calculate the first discount, then paste that result as the new starting price and apply the second discount.

How do I find the percentage off when I know both prices?

Divide the savings by the original price, then multiply by 100.

A $65 item originally priced at $90: ($90 − $65) ÷ $90 × 100 = 27.8% off.

Retailers sometimes show both prices but omit the discount percentage because "save $25" sounds more significant than "save 14%" — the reverse calculation cuts through that.

When does percent off math actually cost people money?

The stakes scale with the purchase. For a $12 item, rough mental math is fine. For larger purchases:

Electronics: A "40% off" claim on a $799 TV should produce $479.40. If the tag says $499, the actual discount is 37.5% — not 40%. On a $1,200 laptop, that gap is over $30.
Appliances and furniture: Sale events often layer a store discount on a manufacturer rebate. Each applies to a different base price — calculate them separately.
Wholesale buying for resale: Margins depend on exact numbers, not rough estimates. Use the commission calculator alongside this one when pricing sales commissions against discounted prices.

Does this work the same way in different currencies?

Yes. A 30% discount on NZ$150 is NZ$45 off, leaving NZ$105. The math doesn''t change with the currency symbol.

UK and EU shelf prices include VAT, so a "30% off" discount applies to a VAT-inclusive price. If you need to separate the tax component — for business expense purposes — use the VAT calculator after calculating the discounted price. The percent-off math itself is unchanged. For US purchases, sales tax is typically added after the discount is applied.

Frequently Asked Questions

How do I calculate 10 percent off a price?

Move the decimal one place left — that''s 10% of any price. On $85: 10% = $8.50. Subtract: $85 − $8.50 = $76.50. For any other percentage, the percent off calculator handles it in under a second without mental math.

What is the formula for calculating percentage off?

Sale price = original price × (1 − discount/100). For 25% off $200: $200 × (1 − 0.25) = $200 × 0.75 = $150. Savings = original price × discount/100 = $200 × 0.25 = $50.

How do I calculate percent off in Excel or Google Sheets?

Use =A1*(1-B1) where A1 is the original price and B1 is the discount as a decimal (0.20 for 20%). Or enter the percentage directly: =A1*(1-20%). Both give the same result as the manual formula.

Does the discount apply before or after tax?

Usually before, in the US. On a $100 item at 10% off with 8% sales tax: $100 − $10 = $90, then $90 × 1.08 = $97.20. In the UK and EU, shelf prices already include VAT and discounts apply to the VAT-inclusive price. Use the VAT calculator to separate the VAT component if needed for accounting.

What''s the difference between "percent off" and "percentage discount"?

Nothing — they describe the same thing. "30% off," "a 30% discount," and "30% percentage reduction" all mean the sale price is 70% of the original. The wording varies by region and retailer but the math is identical.

How do I work out what percentage off I got after buying something?

Subtract the price you paid from the original price to get your savings, divide savings by the original price, and multiply by 100. Paid $56 for something originally $80: savings = $24; percentage off = ($24 ÷ $80) × 100 = 30% off.

Does a percentage off calculator work differently for NZ dollars?

No. The percentage calculation is currency-neutral. A 25% discount on NZ$200 is NZ$50 off, leaving NZ$150 — exactly the same formula as any other currency. Just enter the price and percentage; the calculator doesn''t need to know the currency to return the right answer.
