Discount Calculator
A discount lowers a price by a set percentage, and it helps to see both the saving and what is left to pay. Receipt Caker's free discount calculator takes an original price and a percentage off, then shows the amount you save and the final discounted price side by side.
- How do I calculate a discount?
- Receipt Caker calculates a discount by multiplying the price by the percentage off: saving = price × (percent ÷ 100), and final price = price − saving. Enter the price and pick a percentage above and both figures appear instantly — no mental math.

- 24.00

Finding the price after a percentage off
A discount reduces a price by a set percentage. The saving is price × (percent ÷ 100), and the final price is the original minus that saving. A $120 item at 20% off saves 120 × 0.20 = $24, leaving $96 to pay. Receipt Caker's discount calculator shows both the money saved and the final price side by side, so you see the deal and the damage at once.
There is a faster one-step route to the same answer: multiply the price by one minus the rate. For 20% off, 120 × 0.80 = $96 directly. The calculator handles it either way — type the price, choose or enter the percentage, and both figures appear instantly.
Stacked and successive discounts
Two discounts applied one after another do not simply add up. A 20% discount followed by an additional 10% off the reduced price is not 30% off overall. On a $100 item, the first cut leaves $80, and 10% off that leaves $72 — a combined 28% reduction, not 30%, because the second discount works on the already-lowered figure.
To model successive discounts, run this calculator once, take the result, and feed it back in as the new starting price. That mirrors how registers apply stacked promotions and prevents the common mistake of overstating the total saving by adding the percentages together.
Discount versus markup
A discount lowers an existing price to encourage a sale, while a markup adds to an item's cost to set the price in the first place. They move in opposite directions and start from different figures, so a 20% markup and a 20% discount do not cancel out. Marking a $50 cost up 20% gives $60; discounting $60 by 20% gives $48, not $50.
Use this tool whenever you are reducing a price, and reach for the Receipt Caker markup calculator when you are building a selling price up from cost. Keeping the two straight avoids accidentally pricing below your intended margin.
Showing a discount on the receipt
Once you know the saving and the final price, list the discount as its own line so the customer sees the original price, the reduction, and what they actually paid. That transparency is good for the buyer and gives you a clean record of the promotion for your own books.
Build the document in the Receipt Caker generator, add a discount line item, and it recalculates the subtotal, tax, and total for you before you export a PNG or PDF. Itemising the discount rather than quietly lowering the price makes the transaction easy to reconcile later.
