Retirement Calculator
Project your retirement savings and see if you're on track to retire.
Retirement Calculator
Build a retirement projection using savings, contributions, inflation, and withdrawal assumptions.
Personal timeline
Your age today.
Age when retirement begins.
Used to estimate retirement duration.
Current savings and contributions
Existing retirement savings today.
Regular amount added before retirement.
Assumptions
Use estimated annual return before inflation unless using real returns.
Optional assumption for retirement years.
Inflation reduces future purchasing power.
Retirement income
Usually annual spending before taxes.
Optional annual income that may reduce portfolio need.
No withdrawal rule is universal.
Projected retirement balance
Based on your inputs and assumptions. Actual results may vary.
Estimated savings need
Income need divided by withdrawal rate.
Projected shortfall
Projected balance minus estimated need.
Years until retirement
Retirement age minus current age.
Total contributions
Monthly contribution × months until retirement.
Investment growth
Projected growth above savings and contributions.
Monthly retirement income
Projected balance × withdrawal rate ÷ 12.
Withdrawal rate
Annual portfolio withdrawal assumption.
Inflation-adjusted target
Desired income adjusted to retirement age.
Savings rate estimate
Annual contribution ÷ desired annual income.
Projection-based
Retirement projections rely on assumptions, not guarantees.
Savings-focused
Contributions and time horizon are major drivers of the projected balance.
Planning clarity
Use estimates to compare scenarios and understand trade-offs.

What Retirement Planning Means
Future savings
Retirement planning estimates future savings and income needs.
Multiple drivers
It combines savings, contributions, investment growth, inflation, and withdrawals.
Assumptions matter
Small changes in returns or inflation can change the projection.
Planning clarity
The goal is planning clarity, not a guaranteed forecast.
Retirement Savings Goal Explained
Savings goal
The amount estimated to support future retirement spending.
Income replacement
Replacement rate can be a shortcut, but annual spending may be more useful.
Other income
Pensions, benefits, rental income, or other sources may reduce portfolio need.
Real-world costs
Taxes, healthcare, fees, and lifestyle changes can affect the target.
Contributions, Returns, and Compounding
Starting base
Current savings provide the starting balance for compounding.
Regular contributions
Monthly contributions increase the projected retirement balance.
Compounding
Investment returns can compound over time.
Uncertainty
Higher expected returns may increase projections but involve uncertainty and risk.
Inflation and Purchasing Power
Nominal dollars
Nominal values show future amounts without directly expressing today’s purchasing power.
Inflation-adjusted dollars
Inflation-adjusted targets estimate what future income may need to be to maintain purchasing power.
Withdrawal Rate and Retirement Income
Withdrawal rate
Estimates how much of a portfolio is used each year.
Lower rate
A lower withdrawal rate may last longer but requires more savings.
Higher rate
A higher withdrawal rate may increase depletion risk.
Income sources
Retirement income may come from savings, pensions, benefits, work, or other sources.
Retirement Formula and Method
FV = PV × (1 + r)^n
FV = PMT × [((1 + r)^n − 1) ÷ r]
Retirement Need = Desired Annual Retirement Income ÷ Withdrawal Rate
Future Income Need = Current Income Need × (1 + Inflation Rate)^Years
Shortfall / Surplus = Projected Retirement Balance − Estimated Retirement Need
PV is current savings, PMT is recurring contribution, r is return rate per period, n is number of periods, withdrawal rate estimates annual portfolio use, and inflation rate adjusts future spending needs. Formulas may vary depending on contribution timing, taxes, fees, and cash flow assumptions.
