Have a question, spotted a bug in our math, or want to request a new tool? We would love to hear from you.

How can we help?

Our formulas are heavily tested, but if you notice a discrepancy with official Sri Lankan rates, please let us know immediately.

Is there a specific calculation you do daily at your job? Pitch it to us, and we might build a dedicated tool for it.
