Everyday Money Calculators
Calculate break-even, commission and discount and other everyday money calculations.
Quick money arithmetic for shopping, selling and splitting bills. Most of these answer a one-line question, but two pairs are easy to confuse — markup vs margin, and profit percentage vs margin percentage — and picking the wrong one gives a noticeably different price.

Markup and margin give different prices
A 25% markup on a ₹100 cost gives a ₹125 price, which is only a 20% margin on that price. To earn a 25% margin, the price has to be about ₹133.33. Businesses usually talk about margin; suppliers often quote markup — check which one you have been given.

How a Break-Even Point Is Calculated
Break-even units divide total fixed costs by the contribution margin — how much each unit sale actually contributes once its own variable cost is covered.
Read guideHow a Discount Amount and Final Price Are Calculated
A percentage discount multiplies the original price by the discount rate to find how much is saved, then subtracts that from the original price — and stacking two discounts sequentially never adds up to their sum.
Read guideHow a Tip and Per-Person Split Are Calculated
A tip is added on top of the bill, and the resulting total is then divided evenly across however many people are splitting it.
Read guideHow an Emergency Fund Target Is Calculated
An emergency fund target is monthly essential expenses multiplied by however many months of coverage feel appropriate — a savings goal, not a growth projection, since the fund isn't assumed to earn interest while being built.
