About Discount Calculator

Enter the sticker price, choose whether the discount is a percentage or a flat amount, and the calculator returns the price you actually pay along with the exact saving. The tax field is applied after the discount, the way checkout works: tax is charged on the reduced price, not on the original one, so a 20% off deal followed by 18% GST is cheaper than adding the tax first.

The effective-percentage row matters whenever the discount is a fixed amount rather than a rate — it tells you what "₹500 off" means as a percentage of this particular price, which is the only way to compare two offers. The stacked-deal panel shows the trap of successive offers: 30% then 20% is not 50% but 44%, because the second discount applies to what is left. Nothing you enter is stored or sent anywhere.
