Calculators
"30% off + extra 20% off" is 44% off, not 50% — the second discount applies to the already-reduced price. Flip the stacked toggle on and see the real math.
Where people use it
- Sale shopping — verify the register is applying the advertised discount correctly.
- Stacked offers — "30% + extra 20%" and bank-offer stacking, computed honestly.
- Reverse checks — that "was ₹4999, now ₹1999" tag — what % is it really?
- Invoice building — sale price + GST in one view, with the final payable number.
Discount Calculator — FAQ
Why is 30% + 20% off not 50% off?
The second discount applies to what's left after the first. ₹100 → 30% off → ₹70 → 20% off → ₹56. You paid 56% of the original, so the total discount is 44%, not 50%. The stacked toggle shows this math transparently.
The tag says "up to 70% off" — what will I actually pay?
"Up to" means the best case on selected items. Run your item's real discount here — if a ₹2499 item is in the 30% bracket, the calculator tells you the exact ₹1749.30 payable before tax.
Does the tax apply to the original or discounted price?
Discounted — GST and sales tax always apply to the price you actually pay, after discounts. The Advanced section adds it on the sale price, which is how invoices work.
Is a bigger % always the better deal?
Between stores, compare final prices, not percentages — a 30% off on a lower base price can beat 40% off on an inflated one. Use "Find discount" mode to normalize both to a % and compare fairly.
