About CeylonCalc

Clear answers to Sri Lanka's money questions

CeylonCalc started with a frustration we all share: working out import duty, take-home pay or a loan instalment in Sri Lanka usually means digging through PDFs, outdated forum posts and spreadsheets that nobody trusts. The numbers matter. They decide whether you can afford a car, a home loan or a career move, yet getting them is needlessly hard.

So we built the tools we wanted ourselves: clean, fast calculators grounded in current local rules, that give you a clear answer and show their working. No logins, no paywalls, no selling your data. Just the math, done right, free for everyone.

Founder & Builder, CeylonCalc · Portfolio

I'm a software engineer based in Sri Lanka, working mainly in React and TypeScript. CeylonCalc started because I kept needing to work out EPF payouts, loan instalments, or PAYE tax and kept hitting the same wall: outdated forum posts, PDFs nobody wants to read, and spreadsheets with no way to check if the formula was even right.

I'm not a tax advisor or accountant, and CeylonCalc isn't financial advice. What I do bring is care about getting the arithmetic exactly right and showing the working. Every calculator and article is built and checked directly against the actual Sri Lankan Acts and regulator guidance, not secondhand summaries. If a rate or rule changes, I update it.

I build and maintain CeylonCalc myself. "We" in articles refers to CeylonCalc as a publication, not a hidden team.

What we value
Accuracy first
Every calculator is built around current Sri Lankan tax bands, fund rates and duty structures, and reviewed when the rules change.
Show the working
We break results down so you can see where each number comes from, not just a total you have to take on faith.
Private by default
Calculations run in your browser. We don't ask you to register and we don't store the figures you enter.
Free, forever
CeylonCalc stays free for everyone who needs it. No logins, no paywalls, no subscriptions.
