How MoneyMetrics calculators work

Calculation Methods

Calculators use standard financial math - amortization schedules, compound growth, marginal tax brackets, and CPP/OAS/EI formulas - with parameters published for the labelled year (for example, 2026 federal and provincial brackets and CPP/EI ceilings where applicable). Each tool shows the key assumptions it uses beside the result, so you can see what drove the number. AI-assisted features only send the inputs you submit to the server for that single request; they are optional and never required to get a result.

Data Sources

Rates shown in illustrative or comparison tables may be placeholders or estimates - always confirm current rates, fees, and eligibility with your bank, credit union, or card issuer. Official limits and rules are published by the Canada Revenue Agency and other regulators, including provincial finance ministries for province-specific tax and benefit rules.

How Often We Update

Tax brackets, contribution limits, and benefit thresholds are reviewed and updated when the CRA and provinces publish new figures for the tax year, typically in late fall or early in the new calendar year. Each calculator is labelled with the tax year it uses so you always know which figures you're seeing.

Key Principles

  • All calculations use official 2026 CRA tax brackets and limits
  • Province-specific rules are applied automatically based on the province you select
  • Results are illustrative estimates for planning purposes, not a quote or guarantee
  • Always verify with official sources before making decisions
