Retirement savings grow through a combination of your existing balance compounding over time and new contributions you add along the way — and knowing your projected balance at retirement helps you gauge whether you're on track.
This calculator projects your retirement balance from your current age to retirement age, and estimates a safe annual withdrawal.
How it works
Enter your current age, planned retirement age, current savings, monthly contribution, and expected annual return. The calculator applies future value formulas to both your existing balance and your ongoing contributions, then estimates a safe annual withdrawal using the common 4% rule.
- Enter current age.
- Enter retirement age.
- Enter current retirement savings.
- Enter monthly contribution.
- Enter expected annual return (%).

Examples
Age 30 to 65, $25,000 start
Starting with $25,000 at age 30, contributing $500/month, and earning 7% annually, projects to about $1,188,181 by age 65 — supporting roughly $47,527/year using the 4% rule.
Who should use it
- Checking whether current retirement savings contributions are on track for a target retirement age.
- Comparing how increasing monthly contributions changes the projected retirement balance.
Industry applications
- Personal financial planning
- Retirement and wealth management coaching
Advantages
- Frames the projection around real ages, making it intuitive to plan around a specific retirement date.
- Includes an estimated safe annual withdrawal, not just a lump-sum projection.
Limitations
- Doesn't adjust for inflation or model variable/sequence-of-returns risk during retirement.
Common mistakes to avoid
- Assuming a single fixed annual return rate perfectly predicts decades of real market performance, which fluctuates significantly year to year.
- Forgetting that the 4% rule is a rough guideline, not a guarantee, and doesn't account for market downturns early in retirement.
Best practices
- Run this calculator with a few different assumed return rates (conservative, moderate, optimistic) to see a realistic range of outcomes rather than relying on a single projection.
Tips
- Small increases in monthly contributions made early tend to have an outsized effect on the final balance, thanks to decades of compounding — even a modest bump today is often more impactful than a larger one started later.
