Free financial calculators with the formula shown, the assumptions stated, and none of your data leaving your browser.
Numeraise is an independent site publishing free financial calculators and explanatory guides. It launched in June 2026 and is built and maintained by Rahul Sharma.
We are a small, new project rather than an established institution, and we would rather say so than imply otherwise. What we can commit to is specific and checkable: every calculator states the formula it uses, every assumption is visible and adjustable, and nothing you type is transmitted anywhere.
Each calculator publishes the equation behind it, so you can verify the arithmetic rather than trust a black box.
Calculations run entirely in your browser. Salary, loan and net worth figures are never sent to our servers, because there is no server-side calculation to send them to.
No account, no email gate, no paywall on results. The site is funded by advertising, which is disclosed below.
Every calculator implements a published, standard formula — the future value of an annuity for SIP, the reducing-balance amortisation formula for EMI, Mifflin-St Jeor for BMR, and so on. Where a calculation depends on statutory rules such as tax slabs, contribution ceilings or scheme tenures, we state the assumptions on the page so you can confirm they still apply.
Rates and thresholds change between budgets and policy cycles. If you find a figure that is out of date or a result that looks wrong, please tell us at support@numeraise.com — corrections are the fastest way this site gets better, and we would rather hear about an error than have it sit there.
Numeraise carries display advertising through Google AdSense. Advertisers have no input into our calculators, our articles, or which tools we build. We do not sell your data — there is no personal data collected from calculator use to sell. See our privacy policy and cookie policy for specifics.
Numeraise provides general information and calculation tools. We are not licensed financial advisors, tax practitioners or insurance brokers, and nothing on this site is a personal recommendation. Outputs are estimates based on the assumptions you enter. For decisions involving real money — a tax filing, an insurance purchase, a mortgage — consult a qualified professional who knows your full circumstances. Read the full financial disclaimer.
Corrections, feature requests and questions all go to the same inbox, and a real person reads them. You can also reach us through the contact page.
