Successive Discounts Calculator

Calculate Multiple Discounts in the Correct Order

A successive discounts calculator finds the final price after two or more percentage reductions. Stores may describe this as an extra discount, stacked discount, second markdown, or coupon after a sale. Each new percentage applies to the remaining price, not the original price.

Enter the original price and up to five percentages. Zero values are ignored mathematically, so unused discount fields can remain zero. The tool accepts values from 0% to 100% and rejects negative rates or rates above 100%. It models percentage reductions only.

Use the Successive Discount Formula

For each discount, multiply the current price by one minus the discount rate written as a decimal. With discounts d1, d2, and d3, the final price equals original price multiplied by (1 − d1), (1 − d2), and (1 − d3). The total saving is original price minus final price.

Effective discount percentage equals total saving divided by original price, multiplied by 100. This single rate describes the combined effect. It is normally smaller than the simple sum of the listed percentages because later discounts act on a reduced amount.

Follow a Worked Stacked Discount Example

Start with PKR 5,000. A 20% discount removes PKR 1,000 and leaves PKR 4,000. The next 10% removes PKR 400 and leaves PKR 3,600. A final 5% removes PKR 180 and leaves PKR 3,420.

The customer saves PKR 1,580. Dividing that saving by PKR 5,000 gives an effective discount of 31.6%. Adding 20%, 10%, and 5% would incorrectly claim 35% because it treats every discount as if it applied to the original price.

Compare a Stacked Offer with One Discount

Use effective discount percentage to compare a multi-step promotion with a single markdown. For example, 20% followed by 10% gives 28% off overall. A simple 30% discount on the same eligible original price is better because it leaves 70% of the price instead of 72%.

Make sure both offers start from the same genuine price. A discount from a raised reference price can appear larger while producing a higher final cost. The calculator verifies arithmetic, not the seller’s reference price. Compare the final payable amounts whenever product, quantity, and included services are equal.

If one offer includes a fixed coupon, cashback, points, or free shipping, calculate the percentage-only part here and handle the other benefit separately under the merchant’s rules. Do not convert an uncertain future reward into an immediate saving.

Understand When Discount Order Matters

Pure percentage discounts produce the same final price when their order changes because multiplication is commutative. A 20% discount followed by 10% has the same mathematical result as 10% followed by 20%. The displayed steps differ, but the combined price does not.

Merchant rules can still make the real order important. A fixed-value coupon, spending threshold, maximum discount, excluded item, tax rule, shipping fee, or loyalty credit can change eligibility. This calculator does not model those rules. Apply only percentages that the seller confirms can be combined.

Read and Save the Discount Report

The result table shows the price before and after every percentage. This makes it easier to locate a disagreement with a receipt. The headline final price rounds to two currency decimals, while the calculation keeps the exact decimal fractions internally until display.

Copy the plain-text report for a note, download the detailed CSV for a spreadsheet, or print the calculation. The CSV includes each rate, price before, price after, step saving, total saving, and effective percentage. It does not include personal or payment information.

Check the Checkout Price Before Buying

• Use the price of eligible items, not an unrelated cart total.
• Enter percentages without a percent sign.
• Do not add successive rates together.
• Check coupon exclusions and caps.
• Compare the calculated result with the final checkout screen.

Currency selection converts the original price and all monetary outputs using one dated reference. Percentages remain unchanged. The result excludes tax, delivery, and fixed charges unless those amounts were already part of the original price.

Separate Eligible and Excluded Items

Use the amount eligible for every entered percentage. If a promotion excludes part of a basket, calculate the eligible items separately and add the excluded items afterward. This prevents a coupon from being applied to products the seller does not discount.

When different products receive different rates, run a separate calculation for each group. Add the resulting final prices only after checking tax, delivery, and seller rules. This keeps the report understandable and avoids treating one advertised percentage as a discount on the entire order.
