First discount (%)

Second discount (%)

Method

After first discount = original price × (1 − d₁ ÷ 100). Final price = original price × (1 − d₁ ÷ 100) × (1 − d₂ ÷ 100). Saving = original − final. Effective discount (%) = 100 × saving ÷ original; zero-price input displays 0%.

How this calculation works

Check the checkout price when two percentage discounts are applied in sequence. The second reduction uses the price remaining after the first, so adding the advertised percentages overstates the saving. This calculation is appropriate for percentage promotions without caps or minimum-spend rules; cash coupons require a separate subtraction.

After first discount = original price × (1 − d₁ ÷ 100). Final price = original price × (1 − d₁ ÷ 100) × (1 − d₂ ÷ 100). Saving = original − final. Effective discount (%) = 100 × saving ÷ original; zero-price input displays 0%.

Worked example

This example uses illustrative inputs. Your current result is shown above.

A ₹2,000 item discounted by 20% becomes ₹1,600. A further 10% removes ₹160, producing ₹1,440. The total saving is ₹560, equivalent to 28%, not 30%.

Assumptions and limits

  • Both promotions are uncapped percentage reductions on the same item, with the second applied to the reduced price.
  • Shipping, tax changes, cashback timing, coupon exclusions and intermediate checkout rounding are excluded.

Questions people ask

Does reversing the two percentages change the answer?

No, multiplication gives the same final price for two uncapped percentage reductions. Real offers can differ when caps or eligibility rules apply.

Can I model a single discount?

Yes. Set the second discount to zero; the result then applies only the first percentage.
