Calculators
Need Unix timestamps? Use the Unix Timestamp Converter under Developer Tools.
People open an EMI calculator with a real outstanding, an HRA helper with last month's rent, or an age tool with a date of birth. Those figures are exactly what a “free calculator” site has no reason to receive. Every working tool on this hub evaluates the formula in the page. We do not store a ledger of what you typed.
That privacy story only holds if the math is honest about its limits. An EMI here is standard reducing-balance arithmetic, not your bank's sanction letter. GST inclusive/exclusive splits the rate you enter; it does not file a return. The India income-tax estimator uses baked-in new-regime slabs for a named year and will go stale the next Budget.
Tools that cannot work without a live feed are listed as coming soon instead of inventing a rate: currency conversion, DISCOM tariff lookup, FASTag tolls, and a state stamp-duty matrix. Use a bank, the electricity bill, or the sub-registrar's published schedule for those.
Finance covers EMI variants, SIP and lumpsum projections, FD/RD/PPF sketches, GST, discounts, and a rough new-regime tax figure. Date & time is age, business days (weekends only unless you add holidays), and timezones via the browser. Units are fixed conversion factors, not a calibrated lab instrument.
Construction and solar are rule-of-thumb coverage and kWh math from your inputs. Property multiplies the stamp-duty or brokerage rate you provide; it does not fetch your city's table. Academic and career follow the on-page formula, not your college ordinance or payslip annexure.
Worth knowing before you start, rather than after.
Illustrative math only — not tax, legal, lending, or investment advice.
Stamp duty, DISCOM tariffs, FASTag, and live FX need network data; those entries are coming soon.
India income-tax slabs are hardcoded for a named year and will go stale — verify before filing.
Construction, solar, and vehicle helpers use the rates and wastage you type, not IS-code BOQs or OBD data.
GPA and attendance follow the formula on the page, not your university ordinance.
Unix timestamp conversion lives under Developer Tools — linked below.
No offline mode: there is no service worker, so the hub still loads over the network.
Yes. There is no account, no daily cap, and no watermark on the numbers. You open a tool, enter values, and copy the result.
No. Arithmetic runs in the browser tab. Closing the tab discards the inputs. Site analytics still apply the same way they do on any other page.
No. Results are illustrative. Banks add fees and rate resets; tax slabs on this site are hardcoded and go stale. Confirm with the lender, a CA, or the government portal before you file or sign.
Live currency rates, DISCOM tariffs, FASTag tolls, and state stamp-duty tables need a network data feed. We do not fake those numbers in the browser.
Under Developer Tools, not this hub — it is a programming utility rather than a money or unit calculator.
They use simple coverage and energy formulas from the values you type. They are not a bill of quantities, a structural design, or a net-metering credit from your DISCOM.
