Calculate flat, percentage, and stacked discounts. See final price and total savings instantly.
Enter the original price and choose a percentage or flat first discount, then optionally a second stacked percentage. The tool applies the first discount to get an interim price, then applies the additional percentage on that reduced price (not the original), so stacked discounts compound rather than simply adding up. It shows the final price, total savings in rupees and the true combined discount percentage.
On a ₹2,000 item, a 20% discount brings it to ₹1,600; an additional 10% stacked on that gives ₹1,440. The customer saves ₹560, so the real combined discount is 28%, not 30%, because the second 10% is taken on ₹1,600, not ₹2,000.
No. Stacked percentage discounts compound, so 20% then 10% equals 28% off, not 30%, because the second discount applies to the already-reduced price.
It depends on price. On a ₹2,000 item, ₹500 off (25%) equals a 25% discount; on a ₹4,000 item the same ₹500 is only 12.5%. Use the calculator to compare on your actual price.
Display it clearly against a genuine reference price. Legally, marked reductions should be from a real prior or maximum retail price, so avoid inflating MRP just to show a bigger percentage.
GST is charged on the final discounted value when the discount is shown on the invoice at the time of sale, reducing the tax you collect. Post-sale discounts have separate rules, so check with your CA.
Commmerce has a built-in offer engine: flat, percentage, Buy X Get Y, coupons, and stacking rules.
