Retirement Age Calculator

Use this calculator to estimate the age when your savings may reach a target retirement balance.

What this calculator does

The retirement age calculator projects your savings forward until they reach your target balance. It helps estimate when retirement may become financially possible.

It uses:

• current age
• current savings
• monthly contribution
• expected annual return

Retirement Age Formula

Future Balance = Current Savings × (1 + r)^n + Contributions

Where:

• Future Balance = projected savings
• r = investment return rate
• n = number of years or months projected
• Target = retirement balance goal

Example calculation

If:

• Current age = 35
• Current savings = 100,000
• Monthly contribution = 1,000
• Target balance = 1,000,000

Then:

• Savings grow each year with contributions
• The balance is checked after each year
• When the balance reaches 1,000,000, retirement age is found
• If it takes 24 years, retirement age is 59

The estimated retirement age is 59.
