Retirement Calculator
Plan your retirement with clearer numbers.
Estimate how much you may have at retirement, how much monthly income your savings could support, and whether your current plan is on track. Use the country pages when local retirement rules or a different planning currency apply.
Retirement Calculator
Use the Retirement Calculator to compare financial scenarios with clear inputs, assumptions, and results.
Educational estimate only. Actual outcomes, taxes, fees, market returns, lending terms, and retirement benefits can differ.

Popular retirement and finance calculators
Retirement planning connects to saving, investing, borrowing, taxes, housing, and cash flow. Use the calculators that fit the decision you are working on.
Build a retirement estimate in four steps
Add your age and savings
Start with your current age, retirement age, balance, income, and ongoing contributions.
Choose assumptions
Set an expected return, inflation rate, income goal, and withdrawal rate. Test more than one scenario.
Include retirement income
Add estimated Social Security, pension, or other recurring income instead of treating investments as your only resource.
Compare scenarios
Try a later retirement age, higher savings rate, lower spending target, or different return assumption.
How to use RetirementCalculator.dev
A retirement calculator is most useful when it helps you explore decisions rather than pretending the future is certain. Start with information you know today, then test the assumptions that can change.
Start with a realistic savings picture
Include accounts and assets that are genuinely intended for retirement. Avoid counting money you expect to spend before retirement unless it is deliberately part of the plan.
Do not treat investment returns as a promise
Expected return is an assumption. Markets vary, fees reduce returns, inflation changes purchasing power, and the sequence of gains and losses can matter after withdrawals begin.
Keep public benefits separate from investment withdrawals
Use an official public-pension or Social Security estimate when possible instead of inventing an earnings history. Claiming rules and investment withdrawals are different parts of the plan.
Use the result as a planning range
The projected balance is not a guarantee. Taxes, investment performance, healthcare costs, longevity, pension choices, and changing household needs can all affect the outcome.
Designed for transparent estimates
The site separates mathematical assumptions from country rules and explains what each calculator includes and leaves out.
Formula explanations
Calculator pages explain inputs, formulas, and limitations in plain language.
Primary-source preference
Rule-based figures use official government or program sources where appropriate.
Country rule packs
Country pages can use dedicated rules without mixing them into the general savings engine.
Browser-side calculations
Core calculations run in your browser and do not require an account.
Retirement calculator FAQs
How much do I need to retire?
There is no single number that fits everyone. The amount depends on spending, public or private pension income, taxes, inflation, investment performance, retirement age, longevity, and flexibility in your budget.
What rate of return should I use?
Use a range instead of treating one percentage as certain. Compare cautious, base, and optimistic assumptions and account for fees and inflation.
Does this calculator estimate Social Security?
The main U.S. calculator lets you enter an estimated monthly Social Security benefit and identifies full retirement age from birth year. It does not recreate your complete earnings record.
Can I use the website outside the United States?
Yes. Country pages use local planning currencies and can include dedicated rule packs. Where a public-pension formula is not implemented, the calculator stays focused on savings rather than displaying false precision.
Are the results financial advice?
No. The calculators provide educational estimates based on the inputs and assumptions you choose. Personal financial, tax, legal, pension, and investment decisions may require qualified advice.
