How to Use This Calculator
Enter your Current Age (e.g. 32 in years), Target Retirement Age (e.g. 65 in years), Current Retirement Savings Balance (e.g. 50000 in ), Monthly Retirement Savings Contribution (e.g. 750 in /month), and Expected Annual Investment Return (e.g. 8.0 in %).

The Formula
Future Nest Egg = Current Balance × (1+r)^n + Monthly Contribution × [(1+r)^n - 1] / r
Safe Annual Income (4% Rule) = Total Nest Egg × 0.04
Safe Monthly Income = Safe Annual Income ÷ 12

Understanding Your Result
The 4% rule (withdraw 4% of your portfolio in year one, then adjust for inflation annually) has historically sustained a 30-year retirement with a 95% success rate on a 60/40 portfolio. RMDs (Required Minimum Distributions) begin at age 73 under the SECURE 2.0 Act and are calculated annually as account balance ÷ IRS life expectancy factor. Missing an RMD triggers a 25% excise tax on the amount not distributed (reduced to 10% if corrected promptly).
💡 Financial Planning: Expert Principles & Risk Awareness
- All calculations assume fixed rates and idealized conditions. Real-world results vary due to market volatility, inflation, fees, and taxes.
- The Consumer Financial Protection Bureau (CFPB) recommends consulting a certified financial planner (CFP) for decisions involving significant sums.
- Run at least three scenarios: optimistic, pessimistic, and most-likely — to understand the full range of potential outcomes before committing.
- Inflation averages 2–3% annually in the US (Federal Reserve target). Long-term projections that ignore inflation significantly overstate future purchasing power.
- Tax treatment varies widely by account type (IRA, 401k, brokerage), jurisdiction, and income level. Verify tax implications with a CPA before acting.
- Compound interest works for you in savings/investments and against you in debt. The difference of even 1% in rate, sustained over decades, is enormous.
- Emergency funds (3–6 months of expenses) should be established before optimizing for returns — financial security precedes financial growth.
- Financial projections older than 12 months should be recalculated. Interest rates, tax brackets, and market conditions shift materially year to year.
