Our mission
Most Indian financial calculators are either buried inside a bank's sales funnel, hidden behind a signup wall, or built by news sites where the math hasn't been touched in five years. We wanted something different: fast, free, accurate calculators that just work, in your browser, without giving up your data.
QuickCalc is built and maintained by MFINITY INFOTECH, a GST-registered Indian firm in Ahmedabad. We pay our bills through optional bank/broker referrals and AdSense — never by selling your inputs.
What we believe
Privacy first
Every calculation runs in your browser. Your inputs never leave your device. Period.
Instant, no signup
Sub-100 ms updates as you type. No email gate. No "save your result" tricks.
Built for India
FY-aware tax slabs, Lakh/Crore formatting, Indian schemes (SSY, PPF, NPS) modelled correctly.
Math verified
Every formula tested against the IT Act, RBI directives, and Finance Ministry notifications.
How we keep calculators accurate
For a finance site, "approximately correct" isn't good enough. Here's our process:
1. Source-of-truth references
Every rate, slab, and rule is traced back to a primary source. We don't paraphrase secondary blogs.
2. Quarterly review cadence
PPF, SSY, and small savings rates are revised every quarter by the Finance Ministry. We check the gazette in the first week of January, April, July, and October — and update the same week.
3. Budget-day refresh (early February)
Income Tax slabs, surcharge rules, and Section 87A rebate can change in the Union Budget. We refresh tax-sensitive calculators within 48 hours of the budget speech each year.
4. Visible "Last reviewed" date
Every calculator displays the last review date in its hero. If the date drifts more than 30 days from a known rule change, treat the page with caution and verify against a primary source.
5. Test cases against known values
Every EMI, SIP, FD, and tax calculation is unit-tested against published reference values from the source authorities — so a regression in our code can never quietly ship wrong math.
Who's behind QuickCalc
QuickCalc is built and operated by MFINITY INFOTECH, a proprietorship firm registered in Ahmedabad, Gujarat, India. We are a small team of engineers and finance enthusiasts who use these calculators ourselves — for our own home loans, SIPs, and ITR filings.
