Poptani Labs is a tiny workshop for free web tools — starting with personal finance for the Indian market. Everything runs in your browser, nothing asks for an account, and every tool is free forever.
Simulate a Systematic Withdrawal Plan across 37,000+ Indian mutual funds — withdrawals, remaining value, XIRR and a downloadable schedule, on live NAV history.
Open the simulator →More handy tools are on the workbench — calculators, planners and everyday utilities. Have something you'd love to see built?
Suggest a toolPoptani Labs started with a simple frustration: good financial tools for Indian investors are either locked behind sign-ups or buried in spreadsheets. So we build the tools we wish existed — free, private, and honest about their math. The SWP Simulator is the first; it began life as a Python project and grew into this site.
Everything here is a work in progress and open to feedback. Found a bug or want a feature? Say hello — every suggestion is read by a human.
