All categoriesWhy PMNM.in
Built for how India actually works
CTC that hides employer PF and gratuity. A bigha that changes across a state border. Attendance rules set at 75%. Amounts written in lakh and crore on a cheque. These tools are built around those specifics rather than translated from elsewhere.
Nothing you type leaves your device
Every calculation runs in your browser. No salary figure, no marks, no photograph and no invoice is ever sent to a server — including in the image tools, which use canvas locally.
The formula is on the page
Each tool shows the method, a worked example and its assumptions. If you disagree with an assumption you can see exactly where it enters the calculation instead of trusting a black box.
Rules kept in one place, not baked into code
Tax slabs, land units, exam age bands and marketplace fees live in versioned data files with the financial year and source recorded, so they can be corrected without rewriting a calculator.
No signup, no limits, no dark patterns
No account, no "unlock the full result", no email wall in front of an answer, and no ad dressed up as a button.
Honest about what it cannot do
Where a rule varies by employer, university, state or notification, the tool says so and tells you where the authoritative answer lives instead of pretending to certainty.

These go beyond a single number and compare options — which offer is better, whether switching pays off, whether to rent or buy.

Questions about PMNM.in
Is PMNM.in free to use?
Yes. Every tool is free, no account is needed and there is no usage limit. The site is funded by advertising, which is why you will see clearly labelled ad space around — never inside — the tools.
Do you store the numbers I enter?
No. Calculations run in your browser using JavaScript; the values you type are never sent to a server. If analytics is enabled we record that a calculation happened on a given tool, never what you calculated. Image tools process files locally with canvas and never upload them.
Can I rely on these results for tax, legal or financial decisions?
Treat them as well-informed arithmetic, not advice. Every tool shows its formula and assumptions so you can check the working, but salary structures, tax rules, marketplace fees, state land units and government eligibility criteria all change and vary. Confirm anything consequential against the official source or a qualified professional.
Why is this site focused on India?
Because generic calculators handle Indian problems badly. CTC structures, the 75% attendance rule, bigha that changes by state, lakh–crore formatting, GST-inclusive pricing and RTO-adjusted seller margins are specific problems that need specific tools rather than a converted American calculator.
Do the tools work on a phone?
Yes. Everything is built mobile-first and tested from 320 pixels upward. Most tools also work offline once the page has loaded, since the calculation runs locally.
How do I request a tool that is not here?
Use the Suggest a tool form. Requests that describe a specific decision — rather than "a calculator for X" — are the most useful and are the ones that usually get built.
