How Long Will My Money Last in Retirement? A Clear, Practical Guide

Many people want a simple answer to whether their savings will support them throughout retirement. While no projection can predict the future, evaluating several key factors may help create a more informed retirement income plan.

Start With Spending

Retirement planning often begins with understanding expenses.

Consider separating spending into categories:

  • Essential living expenses

  • Discretionary spending

  • One-time or irregular expenses

Examples of larger expenses may include home repairs, vehicle purchases, travel, or family assistance.

Because spending patterns often change over time, periodic updates may be helpful.

Account for Inflation

Inflation can reduce purchasing power over long periods.

When evaluating retirement income needs, some individuals review separate assumptions for:

  • Everyday living expenses

  • Health care costs

  • Discretionary spending

Using multiple assumptions may provide additional perspective when evaluating future cash-flow needs.

Focus on After-Tax Income

Retirement income often comes from different account types, including:

  • Taxable accounts

  • Traditional retirement accounts

  • Roth accounts

Because withdrawals may receive different tax treatment, many retirement projections focus on after-tax spending power rather than account balances alone.

Consider Social Security Timing

For many retirees, Social Security represents a meaningful source of income.

Evaluating different claiming ages may help illustrate how:

  • Monthly benefits change

  • Portfolio withdrawals may be affected

  • Tax consequences may vary

Some individuals compare multiple scenarios before making a claiming decision.

Understand Sequence-of-Returns Risk

Investment returns rarely occur in a straight line.

Market declines early in retirement may have a different effect than similar declines later because withdrawals are occurring at the same time.

Many retirement analyses include:

  • Below-average market scenarios

  • Average market scenarios

  • Above-average market scenarios

This approach may provide additional perspective regarding potential outcomes.

Plan for Health Care Costs

Health care expenses are often difficult to estimate.

Common costs may include:

  • Medicare premiums

  • Supplemental insurance

  • Dental and vision care

  • Out-of-pocket medical expenses

Some retirees evaluate both typical and higher-cost scenarios when reviewing retirement projections.

Use Scenario Testing

Many retirement evaluations include:

  • Current assets and savings

  • Spending assumptions

  • Inflation assumptions

  • Income sources

  • Tax considerations

  • Portfolio allocation and risk

The goal is to understand how different assumptions may affect retirement income over time.

Review and Adjust Periodically

Retirement planning is often an ongoing process rather than a one-time exercise.

Some retirees periodically review:

  • Spending patterns

  • Portfolio allocations

  • Income sources

  • Tax considerations

  • Major life changes

Adjustments may be considered as circumstances evolve.
