About the retirement calculator
The calculator works in two phases. While you work, your savings grow with your monthly contributions at the pre-retirement return. Once you retire, each year you withdraw the income you need after other income, raised every year with inflation, while the rest keeps earning the retirement return.
The result shows your savings at retirement (also in today’s money), whether the money lasts to the age you chose, and the income your savings could sustain in today’s money. The bar chart tracks the balance by age.
This is a projection with constant rates; real markets vary, so treat the numbers as a planning aid rather than a promise.
Formula
Savings at retirement = S × (1 + i)^m + C × ((1 + i)^m − 1) ÷ i
Need in year k = (Income − Other income) × (1 + inflation)^(years to retirement + k)
Balance next year = (Balance − Need) × (1 + return in retirement)
Example
A 35-year-old with $50,000 saved who adds $800 a month at a 7% return has about $1,381,802 at 65. The calculator then tests whether that balance can pay $40,000 a year (today’s money, after other income) grown with 2.5% inflation until age 90.
