About
Financial tools
built for India.
Zervest is a free financial calculator platform built for India. Every tool is designed around one goal — give you a useful estimate in the least number of clicks, with zero clutter.
Why we built Zervest
Most tools are stuck on outdated tax slabs or interest rates. A PPF calculator showing the wrong rate or a tax tool missing the ₹12 lakh zero-tax threshold can mislead users.
Input fields use accounting jargon — "principal outstanding", "applicable slab rate" — instead of plain language anyone can understand immediately.
Results are buried under clutter, making it hard to focus on the number that actually matters to you.
Zervest addresses all three. Every tool shows its last-reviewed date, uses plain English labels, and keeps the result area clean and focused.
What Zervest covers
How we work
Regularly reviewed
Every tool shows its last-reviewed date. Tax tools are updated after each Union Budget. PPF and FD rates are updated when the government or banks revise them.
Plain language
No bank jargon. Every input field is labelled in the language you already think in — not the language of your salary slip.
Instant results
Results update as you move sliders or type. No submit button, no page reload.
Built for India
Every calculator is designed around Indian financial products — EMI, SIP, PPF, HRA, and the Indian income tax system.
A note on estimates: Our calculators use standard financial formulas and publicly available rates. Results are estimates based on the inputs you provide. Tax figures reflect FY 2025-26 (AY 2026-27) rates as announced in Union Budget 2025.
