Frequently asked questions
Are these calculators accurate for Sri Lanka?
They use commonly published formulas and default rates suited to Sri Lanka. Actual figures from banks, employers or the Inland Revenue Department can vary — always confirm before making financial decisions.
Do you store the numbers I enter?
No. Every calculation runs in your browser. Nothing is sent to a server or saved to your account.
Can I embed or share the results?
Each calculator page includes share buttons for WhatsApp, Facebook, X and email. You're free to link to any calculator page from your own site.
How often are default rates updated?
Default interest and tax rates are reviewed periodically. If a default looks out of date, you can override it directly in the calculator.
