Unlike a simple budget planner, a retirement planning calculator includes compound interest and inflation adjustments, giving you a realistic picture of future income and expenses.
The answer depends on your lifestyle, retirement age, and expected expenses. Common questions include:
A good rule of thumb is the 70–80% rule — you’ll likely need 70–80% of your pre-retirement income each year. But your actual number depends on personal circumstances, healthcare costs, and lifestyle goals.
Our retirement calculators let you test different scenarios to find a personalised savings plan.
For many savers, the bulk of retirement funds come from 401k plans, Roth IRAs, or Traditional IRAs.
Thanks to compound interest, even small, regular contributions can grow into a large retirement fund over time.
If you live in the UK, your pension pot calculator shows how workplace pensions and private savings add up. In the US, Social Security benefits work in a similar way.
Our retirement income calculator considers:

Our calculator allows you to compare your progress against these benchmarks and adjust your contributions to close any gaps.
Q1: How much money do I need to retire?
There’s no one-size-fits-all number. A common rule is to save 70–80% of your pre-retirement income per year. Our retirement savings calculator helps you work out the exact amount based on your age, income, lifestyle, and savings plan.
Q2: How can a retirement savings calculator help me?
A retirement planning calculator estimates your nest egg at retirement, shows how monthly contributions and employer matches grow with compound interest, and calculates how long your money will last in retirement.
Q3: What’s the difference between a retirement savings calculator and a retirement income calculator?
A retirement savings calculator focuses on how much you need to save before retirement. A retirement income calculator estimates how much monthly income your pension pot, IRA, or 401k will provide once you retire.
Q4: How much should I have saved for retirement by age 40, 50, or 60?
Experts suggest these benchmarks:
Q5: Can this calculator be used for 401k or IRA accounts?
Yes. Our tool works for 401k calculators with employer match, Traditional IRAs, and Roth IRAs. You can set monthly contributions, employer match percentages, and expected returns to see your projected balance.
Q6: Does the calculator account for inflation?
Yes. You can enter an inflation rate to see your results in real terms, ensuring your retirement income keeps pace with rising costs.
Q7: What happens if my retirement savings run out early?
If your savings deplete before your planned retirement age, the calculator will show you the “Money lasts until” age. This helps you adjust your contributions, retirement age, or income goals.
Q8: Can I calculate retirement income from pensions or Social Security?
Yes. You can add pension income or Social Security as part of your retirement plan. The calculator offsets your monthly income needs against these guaranteed payments.
Q9: What is a safe withdrawal rate (SWR) in retirement?
A common guideline is the 4% rule, meaning you can withdraw 4% of your savings each year without running out of money too soon. The calculator shows your effective withdrawal rate.
