About ToolHaven
A free, fast, and clutter-free collection of online calculators built for everyday needs - from splitting a restaurant bill to planning your SIP investments.
How it started
Honestly? My girlfriend wanted to play word games on her phone without downloading yet another app. So I built a few: Wordle, Hangman, Word Scramble. She liked them. I kept going.
Then I started adding calculators for stuff I was Googling myself. EMI for a loan I was considering. GST on a freelance invoice. My salary in-hand after deductions. Each one took maybe a weekend, and before I knew it there were 50+ tools sitting in one place.
That's really all ToolHaven is. A side project that got out of hand in the best way. No big vision, no startup pitch. Just tools I wanted to exist, built the way I wanted them: fast, clean, no signup, no nonsense.
The person behind ToolHaven
Why it exists
Most calculator sites make you sit through ads, pop-ups, or a login screen before you can do anything useful. ToolHaven skips all of that. You open a tool, you use it, you leave. No account, no app, no waiting.
Everything runs in your browser. Whatever you type stays on your device. Nothing is sent to a server, nothing is stored, and nothing is logged.
What We Cover
A note on accuracy
These are estimates, not professional advice
The calculators give you a number to work with, not a final answer to act on. For anything that actually matters:
- Financial decisions (loans, investments, tax) - talk to a financial advisor or CA.
- Health questions (weight, calories, body metrics) - consult a doctor.
- Salary and GST calculations are based on standard rules and may not match your exact situation.
