Business Calculators

GST, break-even, profit margins and more — for Indian businesses

Running a business in India means navigating GST filings, calculating whether your pricing covers costs, understanding your debt repayment capacity, and managing ad spend ROI. Our business calculators handle the maths so you can focus on the business.

The GST Calculator is the most-used: enter any amount and pick a GST slab (5%, 12%, 18% or 28%) to instantly get the GST-inclusive or exclusive price, plus the CGST and SGST breakdown. Useful for raising invoices, checking if a supplier is charging the right GST, or filing GSTR-1 manually.

The Break-Even Calculator tells you the minimum sales needed to cover your fixed costs at a given price and variable cost per unit. This is the foundation of every pricing decision. The Profit Margin Calculator goes further: enter your revenue and costs to see gross, operating and net margin percentages — or reverse-engineer the selling price needed for your desired margin.

Working Capital Calculator measures the short-term financial health of your business: current ratio, quick ratio and net working capital from your balance sheet numbers. The DSCR (Debt Service Coverage Ratio) Calculator is used by lenders to assess whether your business generates enough operating income to service debt. Know your DSCR before you apply for a business loan.

The PPC Ad Spend Calculator is built for digital marketers: enter your budget, CPC and expected conversion rate to forecast clicks, leads, cost per lead, and ROAS. It prevents the most common mistake — setting a budget without knowing what it will actually buy.

Frequently Asked Questions

How do I calculate GST on an invoice in India?
For an intra-state supply: GST Amount = Value × GST Rate. CGST = SGST = GST Amount / 2. For example, a ₹10,000 service at 18% GST: GST = ₹1,800, so CGST = ₹900 and SGST = ₹900. Total invoice = ₹11,800. For inter-state supplies, the full GST is charged as IGST. Use the GST Calculator to do this in one click.
What is a good DSCR for a business loan application?
Most banks in India require a minimum DSCR of 1.25–1.50 for business loans. A DSCR of 1.25 means your operating income is 25% higher than your total debt obligations — giving the bank a margin of safety. DSCR below 1.0 means your business cannot cover its debt from operations, making loan approval very unlikely.
How do I calculate break-even for my business?
Break-Even Units = Fixed Costs ÷ (Selling Price per Unit − Variable Cost per Unit). Break-Even Revenue = Fixed Costs ÷ Contribution Margin Ratio. For example, if your fixed costs are ₹2 lakh/month, selling price is ₹500 and variable cost is ₹300, break-even is 2,00,000 ÷ 200 = 1,000 units or ₹5 lakh in revenue.
