Years Until Retirement Formula

Years Remaining = Retirement Age - Current Age

Where:

• Retirement Age = planned age to retire
• Months Remaining = years remaining × 12
• Retirement Year = current year + years remaining

Example calculation

If:

• Current age = 42
• Retirement age = 65
• Years remaining = 65 - 42
• Years remaining = 23

Then:

• Months remaining = 23 × 12
• Months remaining = 276
• If current year is 2026
• Retirement year = 2049

The estimated time to retirement is 23 years.
