What we can help with

Report a clear bug in a calculator result or page layout, ask about an assumption shown on a tool page, or request a clarification about methodology. We cannot provide personalised tax, loan, or investment advice.

How to contact us

We do not publish a phone number. For calculator bugs or assumption questions, email the address shown in Google Search Console / the domain WHOIS contact for calcmantra.com, and include the page URL, your inputs, and what you expected versus what you saw.

For product background and what CalcMantra is (and is not), see the About page. We cannot provide personalised tax, loan, or investment advice.

Before you write

Check the formula, worked example, assumptions, and sources on the calculator page. Many differences versus a bank or payroll portal come from rounding, fees, or inputs that are not on the screen.
