Accuracy and corrections

How to check a result and report an error in a Calculating.ca tool.

Check that the inputs have the correct units and time period. Compare the displayed formula with the assumption you intend to model. Taxes, lending policies and eligibility rules can change.

The October 2026 release corrects Canadian fixed-rate compounding, zero-interest calculations, Nova Scotia sales tax and the scope of the federal income-tax estimator. These are specific corrections, not a claim that the entire library is certified.

To report an error, include the calculator address, input values, result you saw, expected result and an authoritative source. Avoid sending sensitive account or health information. Send a correction.
