Why this matters
Money math shows up constantly — checking an EMI before signing a loan, computing your tax liability under the new regime, projecting SIP returns over 15 years, working out the tip at a group dinner. Most people either do it in a spreadsheet (slow, error-prone) or trust whatever number a bank's website spits out (which is usually marketing-optimized, not accurate).
Every calculator in this hub uses the same formulas an Indian chartered accountant would use, with clear assumptions spelled out in each tool's article section. Inputs are simple, outputs are explained, and the calculations happen entirely in your browser — your salary, your tax numbers, and your loan amounts never leave your device. Useful for sanity-checking what a banker told you, deciding between two loan offers, or just understanding the math.
Common workflows: checking EMI affordability before taking a home loan, comparing old vs new tax regime, projecting whether a ₹10K monthly SIP can reach ₹1 crore by retirement, computing GST on freelance invoices, working out take-home salary after deductions, and deciding between lump-sum and SIP for a windfall.
