Formula used

Nest egg = current savings × (1 + monthly return)^months + contribution × (((1 + monthly return)^months − 1) ÷ monthly return). Sustainable monthly drawdown = nest egg × monthly return ÷ (1 − (1 + monthly return)^−drawdown months).

This is the method behind the answer, so the result can be checked rather than simply trusted.

Assumptions used

What this answer assumes

Scenario estimate only. Check inflation, tax, fees, local retirement rules and professional advice before relying on it.

  • The annual return is a planning assumption, not a guaranteed investment result.
  • Contributions are treated as equal end-of-month deposits until retirement.
  • The same monthly return assumption is used for the drawdown estimate.
  • Inflation, tax, pension rules, superannuation rules, fees, sequence risk and changing returns are excluded.
  • This is educational arithmetic only, not financial advice.

Master’s Tip

How to use the result well

Master’s Tip: run a lower-return version and a 0% version. Retirement plans are fragile when the target only works under an optimistic return assumption.

Method

Nest egg = current savings × (1 + monthly return)^months + contribution × (((1 + monthly return)^months − 1) ÷ monthly return). Sustainable monthly drawdown = nest egg × monthly return ÷ (1 − (1 + monthly return)^−drawdown months).

  1. With 75,000 saved, 750 contributed monthly for 25 years and a 6% annual return, the projected nest egg is about 702,688. A 25-year drawdown at the same return supports about 4,527 per month before tax, fees and inflation.

Assumptions

  • The annual return is a planning assumption, not a guaranteed investment result.
  • Contributions are treated as equal end-of-month deposits until retirement.
  • The same monthly return assumption is used for the drawdown estimate.
  • Inflation, tax, pension rules, superannuation rules, fees, sequence risk and changing returns are excluded.

Method

The calendar projects savings forward before translating the balance into retirement years

The route reuses the live Retirement Calculator: current savings compound monthly, equal end-of-month contributions are accumulated for the years to retirement, and the projected balance is tested against a selected drawdown period and monthly income target.

Formula

Nest egg = current savings × (1 + monthly return)^months + contribution × (((1 + monthly return)^months − 1) ÷ monthly return). Sustainable monthly drawdown = nest egg × monthly return ÷ (1 − (1 + monthly return)^−drawdown months).

Assumptions

The annual return is a planning assumption, not a guaranteed investment result. Contributions are treated as equal end-of-month deposits until retirement. The same monthly return assumption is used for the drawdown estimate. Inflation, tax, pension rules, superannuation rules, fees, sequence risk and changing returns are excluded. This is educational arithmetic only, not financial advice.

Trust boundary

This is educational compound-interest and annuity arithmetic. It excludes tax, inflation, investment fees, pension rules, superannuation rules, sequence risk and professional financial advice.
