Enter a target amount or a retirement monthly budget, tell us your current portfolio — we'll calculate the annual return your inputs mathematically imply. For reference only; not a forecast and not investment advice.
The calculator solves for the annual return rate r that makes your current portfolio plus future monthly contributions grow to your retirement target over the chosen time horizon. A bisection numerical solver is used (no closed-form solution exists when ongoing contributions are present).
When the Monthly Expense method is used, the target is derived as: monthly budget × 12 × (life expectancy − retirement age). This is a simple illustrative "spend-down to zero" approach in today's dollars; it does not adjust for inflation, post-retirement investment returns, healthcare costs, or government allowances (e.g., CSSA, Old Age Allowance). Real-world retirement planning typically requires more granular modelling.
