Quick Financial Calculator
53 free financial calculators. No signup, no ads.
53 free financial calculators for loans, investments, taxes, e-commerce & payroll — no signup, no ads, no data collection. Built solo by a practicing Internal Auditor & Cost Control Specialist with 11+ years of experience. Real audit-grade formulas, not black-box math. Highlight: the mortgage calculator includes full PITI breakdown, PMI detection & a printable amortization schedule. Would love your feedback!
Hey Product Hunters! 👋
I'm Merajul, an Internal Auditor & Cost Control Specialist based in Bangladesh. Over 11+ years of reviewing real estate and manufacturing company finances, I kept running into the same pattern: business owners and professionals making decisions with rough mental math or clunky spreadsheets instead of quick, accurate numbers.
So I built QuickFinCalc — 53 free financial calculators covering loans, investments, taxes, e-commerce margins, marketing metrics, and payroll. No signup, no ads, no data collection. Just instant calculations.
A few things I'm proud of:
→ The mortgage calculator does a full PITI breakdown (Principal, Interest, Tax, Insurance, PMI) with a printable amortization schedule — most free calculators only show basic EMI
→ The SIP calculator supports annual step-up contributions and inflation adjustment
→ Every formula follows the same standards I use in professional audit work — no shortcuts
This is a solo project, built and maintained by me alone (with a lot of AI-assisted development along the way, since I'm not a traditional developer by training). Still actively improving it — currently working through user feedback on which calculators to build next.
Would genuinely love to hear:
1) Any calculator you wish existed that I'm missing?
2) Anything confusing or broken you spot?
Thanks for checking it out! 🙏
