About Retirement Calculator
The Retirement Calculator projects the pot you reach at retirement from your current age, current savings, monthly contribution and expected annual return, compounding monthly, then tests it against the income you want. It separates contributions from investment growth, applies the 4% safe withdrawal rule to estimate monthly retirement income, and uses your inflation rate to estimate how many years the money lasts against your life expectancy. The verdict flags any shortfall years and suggests the extra monthly contribution needed to close it. Nothing is sent to a server.
Use Cases
How to use
Fill in the Your Information block: Current Age, Retirement Age and Life Expectancy.

Set Expected Return and Inflation Rate as percentages, then the Desired Monthly Income you want to live on in retirement.
Read the Retirement Projection panel for the projected balance At Retirement and how many years away that is.
Check the On Track or Needs Attention banner, then Total Contributions, Interest Earned, Monthly Retirement Income based on a 4% withdrawal rate, and Savings Will Last.
Tweak the contribution or retirement age to see every figure recalculate instantly, and follow the Recommendations list for what to change.
