Work out the sale price after a discount, the real discount between two prices, or the original price before the sale. Handles stacked offers and GST.
Why is "30% off plus another 10%" not 40% off?
Because the second discount applies to the already reduced price, not the original. ₹2,499 less 30% is ₹1,749.30, and 10% of that is only ₹174.93. You end at ₹1,574.37, which is 37% off. Stacked discounts always come out lower than the sum.
How do I find the real discount on a "was ₹4,999, now ₹1,999" tag?
Use the second mode. Enter 4,999 as the marked price and 1,999 as what you pay, and the answer is 60.01%. This is worth doing whenever the marked price looks inflated.
Is GST charged before or after the discount?
After, when the discount is shown on the invoice. GST applies to the transaction value, which is the discounted price. On ₹1,000 less 20%, the 18% GST is ₹144 on ₹800, not ₹180 on ₹1,000, so the total is ₹944.
What does "up to 70% off" actually mean?
That at least one item in the store is 70% off. Most will be far less. Check the tag on the item you want and run it through this calculator rather than trusting the banner.
How do I work out a discount in my head?
Find 10% by moving the decimal one place, then scale. For 30% off ₹1,850: 10% is ₹185, so 30% is ₹555, and you pay ₹1,295. For 15%, take 10% plus half of it.
Which is better, 25% off or a flat ₹500 off?
It depends on the price. They are equal at ₹2,000. Below that the flat ₹500 wins, above it the percentage does. Run the price through this page both ways before choosing at checkout.
