Discount Calculator
Key takeaways
- The 20% discount takes ₹400.00 off — the ₹2,000.00 sticker price becomes ₹1,600.00 at the till.
- Every ₹100 of sticker price costs ₹80.00 after the discount.
- Stacking a further 10% at checkout would take the price to ₹1,440.00 — 28% off in total, not 30%, because stacked discounts multiply rather than add.
Price after each discount
Each discount applies to the price left after the one before it, so the last two bars match when no additional discount is entered.
About the Discount Calculator
The Discount Calculator works out what you actually pay after a discount — or after two discounts applied one after the other, such as a coupon at checkout on top of an already-reduced sale price.
Enter the original price and the discount percentage. If a second discount applies on top of the first, enter it as "Additional discount": it is applied to the ALREADY-REDUCED price, not to the original. The bar chart shows the price at each step, so the two reductions read as two separate drops rather than as one number.
"Final price" is what you pay. "Total saved" is the rupee difference from the sticker price. "Effective discount" is the single percentage off the original that the two discounts amount to together.
The one thing this calculator exists to make visible is that stacked discounts do not add up. Two 20% discounts one after the other come to 36% off, not 40%, because the second applies to a price the first has already cut — the remaining fractions multiply (0.8 × 0.8 = 0.64) rather than the percentages adding. "50% off, then an extra 20% off" is 60% off, not 70%. This page computes that compounding exactly, which is what makes the effective-discount figure worth reading.
Frequently asked questions
How do I calculate a discount?
Final price = Original price × (1 − discount ÷ 100). A 20% discount on ₹2,000 leaves ₹1,600, and the saving is ₹400. Where a second discount stacks, multiply by its remaining fraction too: × (1 − additional ÷ 100).
Do two discounts add together?
No, and this is the most common error with sale pricing. 30% off followed by a further 10% off is 37% off in total, not 40% — because the 10% comes off the already-reduced price. The remaining fractions multiply: 0.70 × 0.90 = 0.63, so 63% of the original price remains.
What is an effective discount?
The single percentage that would have produced the same final price in one step. It is always less than the sum of the two discounts whenever both are above zero, and this page shows it precisely so the headline "50% + 20% off" can be checked against what it actually comes to.
Does this include GST?
No. The figures are on the price as entered. In India, GST on most retail goods is charged on the discounted price when the discount is shown on the invoice, so entering the pre-tax price gives the pre-tax result and entering an MRP that already includes GST gives a GST-inclusive result. Our GST calculator handles adding or removing the tax separately.
How do I work out the discount percentage from two prices?
Discount % = (Original − Final) ÷ Original × 100. To check a claimed discount with this page, enter the original price and adjust the discount percentage until the final price matches the one on the tag — the effective-discount output then tells you what the tag is really offering.
Why is the third bar the same as the second sometimes?
Because no additional discount has been entered, so the price after the second step is the price after the first. The bar stays on the chart rather than disappearing, which states plainly that a second discount was available to apply and did nothing, rather than leaving the chart to silently change shape.
