Retirement Calculator Mr Money Mustache Formula

The mathematical engine of the retirement calculator mr money mustache relies on the relationship between your annual savings and your future withdrawal needs.

Variable Meaning Unit Typical Range
Savings Rate Percentage of income saved % 10% – 75%
SWR Safe Withdrawal Rate % 3% – 4%
ROI Annual Real Return % 4% – 7%
Expenses Annual living costs $ $20,000 – $100,000
