Six months or more. You can absorb a lost client or a slow quarter without changing how you work.
Formula: (cash on hand − tax set-aside) ÷ (business costs + personal costs − reliable monthly income). Estimates only, for planning — not financial or tax advice.
Runway is how many months you can keep operating on the cash you hold if income stopped or fell to its current level. It equals available cash divided by your net monthly burn — total monthly outgoings minus the income you can reliably count on.
Three to six months of combined business and personal fixed costs is the usual target, held separately from money set aside for taxes. Freelancers with seasonal or concentrated client income should aim higher.
No. Money set aside for quarterly estimated taxes is already spent — it belongs to the IRS. Counting it as runway is the most common way freelancers overestimate their safety.
Three levers: collect faster (deposits, shorter terms, automated reminders), cut fixed costs (the recurring ones matter far more than one-offs), and add income. Collecting faster is usually the quickest, since the money is already earned.
