Freelance Revenue Is Not the Same as Spendable Income
Client revenue may need to cover business expenses, taxes you reserve yourself and current household costs before anything remains for retirement contributions. Keep those components separate so the calculator does not treat gross revenue as personal cash flow. Business costs such as software, equipment, or contractor fees reduce usable monthly income upfront.
The monthly tax reserve field accepts the exact dollar amount you plan to set aside based on your own tax estimate or professional guidance. The calculator never derives a default tax percentage or recommends specific business structures.
Coast FIRE Can Be Modeled With Uneven Income
Coast FIRE is based on the retirement portfolio, retirement target and time horizon. Freelance income mainly determines how current expenses and any additional contributions are funded. Changing freelance revenue does not alter your underlying Coast FIRE milestone today.
The single projection chart compares your Coast path ($0 ongoing contributions) against your modeled freelance contribution path and the baseline retirement target. Revenue and business cash flow remain separated from investment compounding.
Frequently Asked Questions
Should I use freelance revenue or profit in my Coast FIRE cash-flow calculation?
Keep revenue and business expenses separate. The calculator subtracts entered business costs before determining the amount available for household expenses, tax reserves and retirement contributions.
How should I model freelance income when some months have no clients?
Use the gap-between-clients scenario. Enter the non-retirement cash available and expected revenue during the gap so the calculator can show how many months current expenses can be funded.
What if most of my freelance income comes from one client?
Enter that client's monthly revenue in the client-loss scenario. The calculator can show cash flow without that revenue without estimating the probability that the client relationship will end.
Should quarterly tax payments count as personal spending?
Keep the tax reserve separate from household living expenses. This makes it clear which cash is being reserved for taxes and which amount represents ongoing personal spending.
What if freelance revenue is high annually but arrives irregularly?
Use annual revenue and working-month inputs together with the cash-runway tool. An annual average alone does not show whether cash is available during unpaid periods.
Can I model zero retirement contributions while freelancing?
Yes. Setting contributions to zero should leave the Coast target unchanged while showing how the existing portfolio projects toward retirement without additional contributions.
How should I model unpaid vacation or time between projects?
Treat those months as a temporary lower- or zero-revenue period. The runway calculation can show how current expenses are funded without assuming normal freelance revenue continues.
