Plan loans, investments and taxes with clear, transparent calculations.
Last updated 5 September 2026
Good financial decisions start with a clear number. How much will this loan actually cost? What could a monthly SIP grow into? How much of my CTC reaches my bank account? Which tax regime leaves me better off?
These 15 calculators answer those questions instantly, in rupees, with the maths shown in full. Nothing is stored and no account is needed — open a calculator, enter your figures and read the result.

Interest rates are entered as annual percentages the way Indian banks quote them. Amounts are in rupees with Indian-style grouping (lakh and crore). The GST calculator carries the current two-slab structure (5% and 18%, plus 40% on luxury and sin goods) alongside the pre-22-September-2025 rates. The income tax and salary calculators model both the new and old regimes for FY 2025-26, with FY 2024-25 selectable.
Tax rules and rates change every year. Our calculation layer keeps every rate in a single dated configuration file keyed by financial year, so when the Budget changes a slab we update one place and every calculator stays correct.
A loan EMI is fixed, but the split between interest and principal changes every month — early instalments are mostly interest. The amortization schedule on each loan calculator shows this month by month.
Investment projections (SIP, FD, RD, CAGR) assume a constant rate of return. Real markets do not deliver constant returns, so treat these figures as planning estimates, not promises. Fixed deposits are the exception — the rate is contractually fixed for the term.
The formulas are standard and every calculator is covered by an automated test suite checking normal, boundary and edge cases. Results are mathematically correct for the inputs you provide. Actual bank or fund figures can differ slightly due to rounding conventions, fees and day-count methods.
No. These are calculation tools, not advice. They do not account for your full financial situation, and projected investment returns are not guaranteed. Always confirm the actual terms with your bank, fund house or a qualified adviser.

Indian rupees (₹). The calculators are designed for the Indian market first; the underlying maths applies to any currency if you read the ₹ as your own.
This calculator provides estimates for general information only. Results are mathematical calculations based on the figures you enter and standard formulas. Actual bank, loan, deposit and investment products may differ due to fees, rounding conventions, day-count methods and changing rates and rules. Projected investment returns are not guaranteed and you may get back less than you invest.
