Business and Accounting Calculators
19 calculators · 17 guides
This hub gathers the Calcumetrics calculators and guides for running and analysing a business. Pricing tools come first: the break-even, profit margin, markup versus margin, cost of goods sold and ROI calculators show whether a product or project pays for itself and at what volume.
Operations and finance follow. The working capital, cash conversion cycle, inventory turnover and economic order quantity calculators show how quickly cash moves through the business and how much stock to hold. The liquidity ratios and DSCR calculators show what a banker sees when you apply for credit, and the depreciation calculator covers straight-line and written-down value methods. Indian merchants can also check the cost of card and UPI payments with the MDR calculator.
For investment decisions, the corporate finance group links to NPV, IRR, payback, WACC and DCF calculators, which also have their own hub. The guides include solved numericals written for B.Com and Class 12 accounts students alongside practical explainers for owners, such as current versus quick ratio and COGS versus operating expenses. Everything runs in your browser, so business figures you enter stay on your device.

How to choose a business calculator
Start with pricing. The profit margin calculator gives gross, operating and net margin, and the markup vs margin calculator converts between the two so a 50% markup is not mistaken for a 50% margin. The break-even calculator shows how many units you must sell to cover fixed costs, and ROI measures the return on a single spend.
For stock, work out COGS first, then use inventory turnover and EOQ to see how fast it sells and how much to reorder. For cash, working capital, liquidity ratios and the cash conversion cycle show whether you can pay short-term bills, while DSCR is the test a lender applies before a business loan.
Use depreciation for fixed assets, and the UPI MDR calculator if you take UPI payments in India.
For a payment-cost budget, use the UPI MDR calculator for fees and net settlement with the rate in your provider’s quote, then compare the settlement with your monthly collections.
If you only need a quick percentage, such as a margin, a markup or a return on a single purchase, start with the everyday math calculators.
