Understand the task

To find a discount amount, multiply the original price by the discount rate divided by 100. For example, 20% off ₹1,500 is ₹300, so the reduced price is ₹1,200. For sequential discounts, apply the second rate to the already reduced amount rather than simply adding the percentages.

Important details to check

A markup is added to cost. Profit margin is profit divided by selling price, while markup is profit divided by cost. A 25% markup is therefore not a 25% margin. Taxes, delivery fees and coupons can also change the checkout total.

Recommended workflow

Enter the listed price, enter the advertised discount, check the saving and reduced price, then compare the checkout total and confirm whether tax is included.

Step-by-step checklist

  1. Read the instructions for the file, assignment or service you are working with.
  2. Keep an unchanged copy of important source material.
  3. Use the related tool and review the result instead of assuming every conversion is perfect.
  4. Check the output in the application or context where it will actually be used.

Frequently asked questions

Can two discounts simply be added? Usually not; sequential discounts apply one after another. Is markup equal to margin? No, they use different bases.
