Emergency fund calculator for the self-employed
The standard 3-to-6-month rule was built for W-2 earners with unemployment insurance. This sizes your fund for inconsistent income reality.
Why not the 3-to-6-month rule
The classic 3-to-6-month emergency fund rule is one of the most important ideas in personal finance. It has protected millions of families. It assumes a job loss is a temporary event between two steady paychecks, cushioned by unemployment insurance.
Self-employed earners have no unemployment, no severance, no paid time off. "Getting a new job" is rebuilding a client pipeline, which takes longer than a W-2 job search. And the baseline income is already volatile before anything goes wrong. The principle is right. The number needs to be bigger.
How this calculator works
Starts at six months of essentials (the classic floor). Adds months based on volatility, dependents, primary-earner status, and business age. Caps at twelve months, which is enough for almost anyone short of a one-off catastrophe.
How to build it without going insane
- Starter fund. One month of essentials. Build this first.
- Attack high-interest debt alongside Phase 2 savings. Credit cards at 22% interest eat faster than savings accounts grow.
- Three months of essentials. This is where crisis mode goes away.
- Full target. Build to the number this calculator gave you. Multi-year goal for most people.
