About ToolCanvas

ToolCanvas is a free collection of finance and tax calculators designed for India, alongside a set of everyday unit and CSS converters. Our goal is simple: help you make confident money decisions with tools that are fast, accurate and easy to understand — no sign-up, no clutter, and the actual formula shown on every page.

What we build

We focus on the calculations Indians search for every day — starting with our EMI calculator for home, car and personal loans, including prepayment analysis that shows exactly how much interest you can save. More calculators for SIP, income tax, salary and GST are on the way.

Our approach to accuracy

Personal finance is a "your money" topic, so we take accuracy seriously. Every calculator uses the standard formula banks and financial institutions use, and we show that formula on the page so you can verify the result yourself. Tax-related tools reference the applicable financial-year rules from official sources. All calculations run entirely in your browser — we never see or store your numbers.

How we stay free

ToolCanvas is free to use. We keep the lights on through advertising and occasional partner offers (for example, links to loan or investment providers). These never influence our calculations, and any sponsored link is clearly labelled. See our disclaimer for more.
