Everyday & business calculators
Salary, GST, margins and discounts, worked out cleanly. · 4 free calculators · Updated 6 August 2026
These are the calculations that come up in ordinary working life: what actually lands in your bank account after PF and tax, how much GST sits inside an invoice, what a discount really saves, how many units a business must sell to cover its fixed costs, and whether your EMIs are consuming too much of your income.
The debt-to-income calculator is worth running before any new loan application. Most Indian lenders start declining or repricing when total EMIs cross roughly 40–50% of net income, so knowing your ratio in advance tells you what to expect.
