Retirement Savings Calculator

About This Retirement Savings Calculator

Retirement planning starts with estimating your target nest egg. A common rule is the 4% withdrawal rule — you need 25× your annual expenses saved to retire safely. Social Security typically replaces 30–40% of pre-retirement income. Starting early makes a dramatic difference: saving $500/month from age 25 vs 35 can result in over $500,000 more at retirement.

How the Calculation Works

Required nest egg = Annual expenses × 25. Monthly savings = (Goal − current) / months remaining.

Making the Most of This Tool

Financial calculators are most useful when you run multiple scenarios. Try adjusting the rate and time period to understand how small changes in return rate or investment duration affect outcomes. The power of compound growth means starting earlier almost always outweighs starting with a larger amount.

Important Considerations

All financial projections involve assumptions that may not hold in reality. Market returns fluctuate, interest rates change, and individual circumstances vary. Use this calculator as a planning tool to understand ranges and general direction, not as a guarantee of specific outcomes.
