Frequently asked questions

A guideline suggesting you can withdraw about 4% of your savings in the first year and adjust for inflation afterwards.

How the retirement projection works

Your current savings and monthly contributions grow at the expected annual return, compounded monthly, until retirement. The income figure applies a withdrawal rate to that balance; 4% per year is a widely cited guideline for making savings last around 30 years.

Pensions and social security are not included, and inflation reduces what future money buys. Use a conservative real return and revisit the plan every year. This is not financial advice.
