What is a retirement?
A retirement calculator models how regular contributions and investment growth could build a retirement balance over time. Change your planned retirement age, savings and assumed return to explore scenarios. Actual returns vary, and this projection does not account for taxes, fees or inflation unless you model them separately.
Formula and calculation method
Future value combines the compounded current balance with the future value of regular end-of-month contributions, using the monthly equivalent return.
