RRSP Refund Calculator

Educational estimate using Ontario + federal 2025 marginal brackets. Simplified (doesn’t model credits, surtaxes, CPP/EI, or other deductions).

How this works
  • RRSP contributions reduce taxable income for the year you claim them.
  • The value depends heavily on your marginal tax rate.
