Free Legal Tools & Calculators

Ten calculators built on the rules that actually govern the answer — the Limitation Act, Section 138 of the Negotiable Instruments Act, the multiplier method from Pranay Sethi, the Payment of Gratuity Act. No sign-up, nothing to download, and each one shows its working so you can check it.

AdvoMitra is a legal technology platform and is not a law firm. These tools and drafts are provided for general information. They are not legal advice, and no template fits every situation — have an advocate review anything you intend to rely on.

Frequently asked questions

Are these tools free to use?
Yes. All of them are free, need no registration, and nothing is stored on our servers — the calculations run in your browser.
How accurate are the results?
The formulas follow the governing statute or Supreme Court decision, and each page sets out the rule applied. They are indicative: the facts of a case, state-specific variations and judicial discretion all affect the real outcome.
Can I rely on these for a court filing?
Treat them as a starting point for a conversation with an advocate, not as a substitute for advice. Figures produced here are estimates, not opinions.
Do you store what I enter?
No. Every calculator runs entirely in your browser. Nothing you type is sent to us or saved.
