How rounding rules differ
Cash rounding is often applied to the final payable amount, tax amounts, or displayed prices. Even with the same 0.05 step, nearest, round up, and round down produce different results.
Store rules are easier to misread when the apply target and tie rule are omitted, so this page keeps the rule summary visible next to the result.
FAQ
Can I round to 0.05?
Yes. Choose 0.05 as the step, then select round half up, round up, round down, or nearest. In nearest mode you can also choose how ties are handled.
Can I use it together with tax calculations?
Tax calculation itself belongs in a separate tool. This page only rounds the value you enter, and it is designed to reuse the same rule definition as a tax-conversion workflow.
Can I paste multiple values at once?
Yes. The batch tab accepts multiple lines and lets you export the result as CSV or copy it as TSV.
Can it round negative amounts?
Yes. Returns and discounts can be rounded as negative values. Because the meaning of round up, round down, and tie handling changes with negatives, always review the result carefully.
Does it avoid decimal precision errors?
Yes. The calculation uses decimal-safe integer scaling internally, so steps like 0.05 are not handled with binary floating-point arithmetic.
Important notes
- Rounding rules differ by store, country, and payment type. Always choose the rule that matches your own policy.
- This tool calculates from the settings you selected. It does not decide the legally correct rule for you.
- Inputs stay inside the browser and are not sent to the server.
- Round up and round down are easy to misread for negative values, so review the examples before sharing a rule.
