FAQ
How does inflation affect my retirement savings?
Inflation reduces the purchasing power of your money over time. A monthly spending goal of $4,000 today will require significantly more nominal dollars in 30 years to buy the same goods and services. This calculator automatically projects your target monthly expenses using your custom annual inflation rate.
What is a safe withdrawal rate or return rate post-retirement?
Historically, financial planners suggest a conservative annual return rate of 3% to 5% post-retirement, as retirees transition to lower-risk assets like bonds and treasury bills to protect their nest egg. A pre-retirement return rate is typically higher (6% to 8%) when invested in equities.
How is the suggested monthly contribution calculated?
If your projected nest egg falls short of the required nest egg, the calculator computes the monthly payment necessary to cover the difference. It takes into account compound growth on both your existing savings and your future contributions up to your retirement age.
