How the discount is worked out
The saving is simply original price × discount ÷ 100, and the final price is what's left after subtracting it. A 20% discount on ₹1,000 saves ₹200, so you pay ₹800. The calculator updates live as you change either field.
Stacking and sanity checks
Shops often advertise big headline percentages, but the rupee saving is what actually matters. Use this to compare two offers — a flat ₹500 off versus 30% off — and to check that a "sale" price is really the discount claimed before you buy.
Frequently asked questions
How do I calculate 25% off?
Enter the original price and 25 in the discount field — you'll see both the saving and the final price.
Can it handle two discounts?
Apply one, note the final price, then enter that as the new original price and apply the second discount.
Does it include GST?
No — this is the discount only. Use the GST calculator to add or remove tax.
