Project your retirement savings, estimate the nest egg required for your target income, and see whether you’re on track. Results are educational estimates — not financial advice.
This retirement planning calculator estimates how your savings could grow based on current balance, ongoing contributions, expected return, and time until retirement. Use it to test contribution levels, retirement ages, and return assumptions. The output is an estimate — real markets vary, and inflation affects purchasing power. For a more cautious plan, run a lower return scenario and a higher contribution scenario. Pair this with an emergency fund and debt plan so your retirement contributions remain consistent through life events.
Practical tips: include employer match if available; increase contributions gradually (e.g., 1% per year); test a lower return scenario to plan conservatively. Limitations: results assume fixed rates and steady payments/contributions. If your situation changes (rate changes, fees, irregular income), rerun the calculator with updated inputs to keep your plan accurate.
Retirement planning improves with consistency. If you can’t raise contributions today, focus on making contributions automatic and increasing them when you get a pay rise.
Keep assumptions realistic. The biggest drivers are time, contributions, and return rate.

We simulate month-by-month growth, adding your contribution each month and compounding at an estimated rate. The “required nest egg” uses your target income and a withdrawal rate (e.g., 4%).
Not always. Returns are unpredictable. Contributions, costs, and consistency matter. Use conservative assumptions and revisit your plan yearly.
That’s how this tool treats it by default. If you enter inflation, we inflate the target income to retirement and show an inflation-adjusted pot for comparison.
No. It’s a planning guide. Longer retirements, poor market sequences, and fees can reduce sustainable withdrawals.
Start with your current age, retirement age, existing savings, monthly contribution, expected return, and target retirement income. Then compare the projected pot with the required nest egg to see whether you are on track.
The biggest variables in any retirement calculator are time, contribution rate, investment return, inflation, and withdrawal assumptions. Time and consistency usually matter more than trying to chase a very high return.
For example, increasing contributions early in your career can have a larger long-term impact than waiting ten years and contributing more later. That is why this retirement calculator is most useful when you test multiple scenarios instead of relying on one projection.
This calculator uses standard financial formulas and simplified assumptions (for example: constant rates, regular payments, and rounding). Real-world results can differ due to fees, taxes, rate changes, compounding conventions, and account rules.

Use these tools together to stress‑test your plan (fees, contributions, debt payoff, and cash flow).
It estimates how your savings may grow over time based on current savings, contributions, years to retirement, and an assumed return rate.
For planning, many people use a conservative range such as 4%–7% depending on risk. Higher assumptions can overestimate outcomes.
Some projections show nominal growth. To plan in today’s money, compare your return assumption against expected inflation.
That depends on your target amount, timeline, and expected return. Use the calculator to test scenarios and adjust contributions.
