Coast FIRE Calculator for Couples: How to Estimate a Shared Number
Quick Answer
Couples can calculate Coast FIRE by using combined invested assets and shared retirement spending, or by running separate calculations for each partner. Separate calculations are useful when partners have different ages, retirement dates, pensions, or account balances.
Two Practical Methods
Use a combined calculation when both partners share the same target retirement age and household spending. Use separate calculations when one partner plans to retire earlier or has a pension, Social Security estimate, or account balance that should be modeled separately.
Inputs to Agree On
- Shared retirement spending
- Target retirement age for each partner
- Current invested assets
- Expected real return
- Pension or Social Security income
