About FinanceFlow

Our Story

FinanceFlow started in late 2024 when I was trying to figure out my home loan EMI. I opened five different calculator sites. Two gave different answers for the same inputs. One covered the result with a popup asking me to sign up. Another required me to share my phone number to "unlock" the amortization table.

I am a developer, not a financial advisor. But I know when a formula is wrong and when a site is designed to frustrate you into clicking something. So I spent a weekend building four calculators that just worked — correct formulas, instant results, no forms to fill.

FinanceFlow has grown from those four tools to 20+ calculators covering everything from SIP returns to GST invoices. I update every calculator manually when tax slabs change or when RBI revises benchmark interest rates. The site will always be free.

What We Do and What We Don't

What we do:

• Publish the formula used in every single calculator
• Update tax slabs and interest rates when they officially change
• Tell you clearly when a result is an estimate vs an exact figure
• Work on every device without requiring sign-up or download

What we don't do:

• Store, log, or transmit your financial inputs
• Require email or phone number to use any tool
• Show fake bank offers unless connected to real affiliate partners
• Lock any feature behind a paywall
