MarginMath: Pricing Calculator

MarginMath is the pricing calculator for people who sell. Whether you run a shop, sell online, resell, or just want to check a price, get a clear answer without a spreadsheet.

PRICE IT RIGHT. KNOW YOUR MARGIN.

MARGIN & MARKUP Enter any two of cost, selling price, profit, margin or markup and the rest work themselves out as you type. See your profit per unit, and how a price with tax splits into cost, tax and profit.

DISCOUNT Find the sale price, the amount you save, or the percentage off. Add an extra discount at checkout and see the real total: 30% then 10% comes to 37% off, not 40%.

GST & TAX Add tax to an amount or take it out of a price that already includes it. Pick a common rate or enter your own, and see the tax split out, including CGST, SGST and IGST for inter-state supply.

MARKDOWN PLANNER Planning a sale? Find the tag price that still leaves the margin you want after the markdown, and round it to a price that sells, such as ending in 99.

BREAK-EVEN Enter your fixed costs, price and variable cost per unit. See how many units cover your costs, the contribution per unit, and a chart of where loss turns into profit.

UNIT PRICE Compare packs of different sizes and see which is the better buy per gram, litre or unit.

HISTORY Save any calculation with one tap. Your History keeps them newest first, grouped by day, colour-coded by calculator. Search them, filter by calculator, reopen one to keep working, and undo a delete if you slip.

BUILT FOR WHERE YOU SELL Choose your region and MarginMath uses its currency, number format and default tax rate. India, United States, United Kingdom, Germany, Canada, Australia, United Arab Emirates and Japan are built in. Change the tax rate, units and decimal places in Settings.

PRIVATE BY DESIGN No account and no sign-up. Your saved calculations and settings stay on your device. MarginMath is free and shows ads; you choose whether ads can be personalised.
