How does this calculator work?
Sale price = original × (1 − discount/100). Savings = original × discount/100. A 20% off discount on a $100 item gives a $80 sale price and $20 saving. Stacked discounts multiply rather than add: two 20% discounts yield 36% off, not 40%.
Formula
How this is calculated
A percentage-off discount reduces a price by a fixed proportion of its original value. Multiplying the original price by the discount rate (expressed as a decimal) gives the saving; subtracting that from the original yields the sale price. For example, 20 % off a £80 item saves £16, leaving a sale price of £64.
The donut chart shows the split between what you pay and what you save, which helps visualise how substantial a discount really is. A 10 % discount saves a small slice; 50 % off cuts the price in half; 75 % off means you pay just a quarter of the original price.
Note that stacked discounts do not simply add. Two consecutive 20 % discounts total 36 % off, not 40 %, because the second discount applies to the already-reduced price. To find the effective combined discount of multiple markdowns, apply each one sequentially: sale price₁ = original × 0.8; sale price₂ = sale price₁ × 0.8.
Frequently asked questions
Multiply the original price by (1 minus the discount divided by 100). For example, 30% off £150 gives £150 × (1 − 0.30) = £150 × 0.70 = £105. The saving is £150 − £105 = £45.
Divide the sale price by (1 minus the discount rate). If an item sells for $63 after a 30% discount, the original price is $63 ÷ 0.70 = $90. This calculator computes the reverse direction — swap the inputs manually to check.
No — stacked (sequential) discounts multiply, not add. A 20% discount followed by a further 15% discount gives a final price of original × 0.80 × 0.85 = original × 0.68, which is a 32% total reduction, not 35%. Always apply each discount to the running sale price, not the original.
