Can I retire before my pension or Social Security starts?

Plan the bridge years separately

A single annual income number can hide a large early gap. Start with the spending your investments must fund in each period: annual spending minus income available during that period, with withdrawals never below zero.

• Before a pension begins, investments may need to cover all your spending.
• When the pension starts, the investment withdrawal falls by the income available to spend.
• When Social Security or another source begins, withdrawals may fall again. Temporary work or rent that ends can make them rise.

Later income cannot repair an earlier unfunded period. The Timeline checks the path, not just whether total lifetime income looks sufficient.

Worked example: retire at 55, income starts later

Consider a fictional person retiring now at exactly age 55 and planning through age 85. Spending is $60,000 a year. A pension supplies $18,000 a year from age 60, and Social Security supplies $24,000 from age 67; both continue through the horizon.

Start with $660,000 in other investments and 3 BTC at an assumed price of $100,000: $960,000 total. Use 0% static bitcoin growth, 0% other-investment growth and 0% inflation; no further savings or other income; spend other investments first. These are teaching assumptions, not forecasts, benefit estimates or recommended settings.

1. 55 to 60: No retirement income. Investments supply $60,000 a year for 5 years: $300,000.
2. 60 to 67: The pension covers $18,000 of spending. Investments supply $42,000 a year for 7 years: $294,000.
3. 67 to 85: Combined income is $42,000. Investments supply $18,000 a year for 18 years: $324,000.

Total investment withdrawals are $918,000, leaving $42,000 at age 85 under these assumptions. The periods end at, rather than include, the next boundary age.

If the same pension starts at 65 instead of 60, the portfolio must supply an extra $90,000. Required withdrawals rise to $1,008,000, creating $48,000 of unfunded spending with the same starting investments. Timing matters even though the eventual annual income is unchanged.

This arithmetic is checked against the actual Timeline projection. It is not evidence that $960,000 is enough for a real household to retire.

Build your own income timeline

1. In My Finances, enter spending and investments you intend to use for retirement. Add your birth date in Preferences so age-scheduled income has a date reference.
2. Add each income source separately, with the amount available to spend, its start age and any end age. Mark sources that continue in retirement; use planned income for amounts not currently earned. End ages are exclusive.
3. In Retirement Timeline, choose when to retire and review the planning horizon, growth, inflation and withdrawal approach. Moving retirement does not move the ages you set for income.
4. Compare income and spending, then inspect investment balances and any unfunded period. The charts show annualized cash-flow rates; Timeline details show actual prorated amounts and ending balances for each period.

Try a later income start, lower income or higher spending. A plan that only works with every assumption at its most favorable deserves another look.

What the projection assumes

Amounts are in today’s purchasing power, not future nominal dollars. Scheduled income amounts remain constant in real terms while active—effectively assuming they keep pace with inflation. A pension with no cost-of-living adjustment may lose purchasing power; the Timeline does not model its separate inflation adjustment.

Withdrawals happen at the start of each projection period, followed by growth adjusted for inflation. Income transitions split periods and partial periods are prorated. The withdrawal approach controls which investments are spent first. Retirement income above spending does not get reinvested, and no minimum ending balance is required.

The model does not calculate Social Security eligibility, claiming-age benefit changes, pension rules, taxes, fees or account-access restrictions. Enter your own income estimates and check when investments can actually be accessed. Smooth assumed growth is not an adverse-return sequence or a probability of success. A funded result is conditional, not a recommendation to retire.
