About FinBuddy
The FinBuddy Story
FinBuddy was built by Harshit Suwan and Bhanu Pratap Singh Deo, B.Tech. students at Birla Institute of Technology, Mesra, Ranchi. We got tired of searching for a finance calculator that actually explained what the numbers meant — every tool we found showed a result and stopped there. FinBuddy exists because we believe understanding your EMI, your tax liability, or your SIP corpus should not require a CA or a finance degree. Every calculator on this platform is built to show you not just the number, but what it means for your financial decisions.
How We Keep Data Accurate
Every formula on FinBuddy follows official government sources — the Income Tax Department, RBI, EPFO, PFRDA, and the Ministry of Finance. We update regulatory data within 24 hours of Budget announcements and RBI rate changes. Our calculators reflect the GST 2.0 structure effective September 2025, the expanded 8-city HRA metro list effective April 2026, and FY 2026-27 income tax slabs as confirmed in Union Budget 2025. When rules change, the calculators change with them — not days later.
What FinBuddy Is
FinBuddy is a premium AI-powered financial intelligence platform built for salaried employees, investors, and taxpayers in India. It provides 15 outcomes-focused planning modules covering loans, investments, taxes, retirement, and savings — all updated for FY 2026-27 and Budget 2025.
