About Rupeeful
Make every rupee count.
Why this site exists
Most online finance calculators for Indian users are built on shaky defaults. They use 3% inflation (a US figure) when India's long-run average is closer to 6%. They show a SIP corpus number but don't check whether it actually survives a 30-year retirement. They list “Section 80C” as a feature without explaining how the new tax regime makes it irrelevant for most people now.
Rupeeful is an attempt to do this right — calculators that are accurate to the rupee, articles that explain the math behind them, and content that takes Indian-specific quirks (LTCG exemption, RBI inflation targeting, EPF rule changes) seriously.
Free, no signup, no ads. The calculations run entirely in your browser; we don't store or transmit your inputs.
Principles
Math you can verify
Every calculator's formula is shown on the page. Outputs are cross-checked against RBI / EPFO / Income Tax Department references. No black-box approximations.
India-first defaults
Indian inflation (6%), Indian tax slabs (FY 2025-26), Indian compounding conventions (quarterly for FDs, monthly for SIPs). No copy-pasted US assumptions.
Free forever, no signup
No accounts, no upsells, no email gating. Calculations run in your browser. We never log inputs.
Who built it
Rupeeful is built and maintained by Pranay Mate, a senior full stack developer working on fintech and sports-tech products in India. The site is open about its assumptions, formulas, and rate sources — none of which are hidden behind a paywall or a registration form.
