About this tool
What does "40% + extra 10% at checkout" really cost? Stacked discounts don't add up; the tool calculates them correctly, subtracts coupons and shows the effective percentage. It also finds the percentage from list and sale prices.
The installment tab gives the monthly payment and any financing cost as a table. The comparison tab puts different packs and promotions side by side by unit price: which one is actually cheaper?
Frequently asked
The second discount applies to the already-discounted price: 1000 → 600 → 540. Effective discount is 46%.
Use the bank's or store's monthly cost rate. If you know the rate including taxes, enter that; otherwise leave it empty for an interest-free split.
Each option's price is divided by its quantity (unit price); the lowest is marked. For "buy 3 pay 2", price = price of 2, quantity = 3.
