Retirement calculator with fees, inflation and income scenarios
Enter savings, yearly contributions, ages, return, fees and inflation. Calculator24 shows the projected retirement balance, today's-dollar equivalent and first-year income at your chosen planning withdrawal rate.
What the retirement projection calculates
The engine compounds the current account once per year, subtracts the entered fee rate from the return scenario and adds the annual contribution at year-end.
Growth and inflation formulas
Nominal dollars describe the future account statement. Dividing by cumulative inflation expresses that same projection in approximate present purchasing power.
balance_t=balance_(t−1)×(1+return−fee)+contributionreal balance=nominal balance÷(1+inflation)^yearsfirst-year withdrawal=balance×withdrawal rateWorked planning example
Start with $100,000 at age 35 and model 32 annual contributions through age 67. The year-by-year table separates the running balance from the cumulative cash contributed.
Why fees matter
The Department of Labor explains that fees paid from a retirement account reduce its investment returns. A small annual percentage can compound into a material difference over decades.
Contribution limits and taxes
IRS limits and eligibility rules change by plan type and year. This calculator accepts a scenario amount but does not decide whether a contribution is permitted, deductible or taxable.
How to use scenarios responsibly
Compare conservative, middle and optimistic return assumptions. Real markets vary from year to year, and retirement outcomes also depend on taxes, withdrawals, longevity and asset allocation.
Inputs the projection separates
| Input | Role |
|---|---|
| Return | Nominal growth scenario before entered fees |
| Fees | Annual drag on modeled return |
| Inflation | Converts future dollars to today's purchasing power |
| Withdrawal rate | Illustrates first-year retirement income |
| Desired spending | Creates an income gap comparison |
Frequently asked questions
Are investment returns guaranteed?
No. The rate is a constant scenario and real returns vary.
When are contributions added?
This model adds one contribution at the end of each projection year.
Are fees included?
Yes. The annual fee percentage reduces the modeled return.
What are today's dollars?
They divide the future amount by assumed cumulative inflation.
Does this enforce IRS limits?
No. Check current plan-specific IRS rules and eligibility.
Does the result include Social Security?
No. It projects only the savings inputs entered here.
What to keep in mind
This is a deterministic scenario, not a forecast or investment recommendation. It excludes taxes, contribution timing within each year, employer matching and variable market returns.
