Retirement Income Calculator
Income in retirement is cash flow, not just account balances. This tool connects portfolio size, withdrawal assumptions, and spending so you can see whether your desired lifestyle fits the assets and timeline you model.
Quick answer
Set retirement spending in today’s dollars (or as modeled), align inflation, and review first-year withdrawal needs against projected portfolio value. The calculator highlights whether your spend path fits common sustainability checks in the engine.

How to use this calculator
- Name your spending in layers: Essentials vs discretionary helps when you need flexibility later.
- Pair spending growth with inflation: Fixed nominal spending is not the same as flat real spending.
- Anchor ages and horizon: Current age, retirement age, and how long the portfolio must fund spending drive every output.
- Separate real from nominal: Inflation pairs with spending growth; real return pairs with long-run sustainability.
Drivers of sustainable income
Withdrawal rate rules, portfolio return distribution risk, and longevity assumptions interact. Higher spending or earlier retirement raises the bar on assets and savings.

Income from work vs portfolio
If part-time work is in the picture, model it explicitly rather than lowering portfolio need without documenting the tradeoff.
Real-world example
- Example: $8k/mo lifestyle target: The model translates spending into portfolio need under your withdrawal rule and horizon, then shows readiness against current savings — useful for seeing the gap in dollars, not vibes (illustrative).

If income need exceeds the model
Reduce spend, extend working years, or increase savings — the calculator shows which lever buys the most readiness per unit of change.
FAQ
Is readiness a guarantee?
No. It is a modeled score from your inputs. Use it to prioritize savings, timeline, and spending tradeoffs.
Should I trust one Monte Carlo run?
Use it as a stress lens. If success is high but fragile to small return cuts, widen your cushion.
Does this replace personalized advice?
No — especially for tax, healthcare, and estate complexity.
