The fastest way to reach us is email. Write to contact@nationcalculator.com and we will read it. We aim to reply within a few working days, and to act on a genuine correction considerably faster than that.
Reporting an error
This is the message we most want to receive. If a figure looks wrong, a tax slab is out of date, or an explanation is misleading, tell us — a wrong number on a finance or tax page is a genuine problem and we would rather hear about it from you than leave it standing.
To make it quick to fix, it helps to include:
- The page — the full URL, or just the calculator name.
- The inputs you used, so we can reproduce it exactly.
- What you expected, and ideally where that figure comes from — an official schedule, a bank statement, a published example.
Confirmed errors in a formula are fixed and covered by a regression test so the same mistake cannot return unnoticed. Errors in a rate are corrected and the page’s review date updated. We explain that process in more detail on our methodology page.
Flagging a rate change
Tax slabs, GST rates, small-savings interest, stamp duty, EPF and EPS rules and state-level charges all change on their own schedules, and some change with very little notice. If you work with one of these regularly and spot that we are behind, a short note with a link to the notification is genuinely useful and is usually acted on the same week.
Suggesting a calculator
If there is a calculation you keep doing by hand, tell us what it is and, if you can, how you currently work it out. The ones we are most likely to build are those with a clear formula, a citable source, and a real decision attached to the answer.
What we cannot help with
We are not able to give personal financial, tax, legal or medical advice, and we will not attempt to. If you write asking which regime you should elect, whether to take a particular loan, or what a test result means, we will say the same thing the pages do: the answer depends on facts specific to you, and it belongs with a qualified professional who can see them.
We also cannot look up your individual account, return, PF balance or policy — we hold no data about you. Every calculation on this site runs in your browser and nothing you enter reaches us, which is set out in our privacy policy.
Other enquiries
Press, partnership, licensing and advertising enquiries reach us at the same address — putting the subject in the first line helps it get to the right place. For how we handle data and cookies, see the privacy policy and terms of use.
