How to use this calculator
- Enter monthly revenue and expenses.
- Add tax reserve percentage and average client payment delay.
- Use runway and emergency fund target to assess cash stability.
Calculate freelance net cash flow, runway, emergency fund target, and late payment risk. Use it to manage inconsistent client payments and protect business stability.
Positive cash flow and several months of reserves reduce stress from delayed invoices, taxes, and inconsistent project volume.
Cash flow is different from profit. Late invoices can create cash pressure even when projects are profitable.
With $7,000 revenue, $4,000 expenses, 20% tax reserve, and $12,000 cash reserve, net cash flow is $1,600 and runway is 3 months.
Many freelancers aim for 3 to 6 months of expenses because income and client payment timing can be irregular.
Three months is a basic cushion, while six months or more provides stronger protection against slow periods.
Track invoice timing, tax reserve, monthly expenses, and cash runway rather than only looking at booked revenue.
Late payments can reduce available cash, delay tax savings, and force reliance on reserves even if the work is profitable.
Divide current cash reserve by monthly expenses to estimate how many months the business can operate without new income.
