Free client lifetime value calculator
The most valuable client is usually the one you already have — priced properly. Freelancers price the next project and forget the client: a client who pays $2,400 a project, three projects a year, and stays three years is not a $2,400 client. They are a $21,600 client — and $13,500 of that is profit, after a $900 cost to serve each project. One number, two decisions changed: how much effort keeping them deserves, and how dangerous losing them is — because replacing them means winning nine more projects of the same size before you are back where you started. Enter one client's real numbers and this calculator prices the whole relationship.
One client, priced whole
Price the client you have, not the one you hope for: last year's real project sizes and this year's real rhythm, not the pipeline you are picturing. The lifetime value is only as honest as the four numbers feeding it.

Enter a client's numbers and this line explains how to read the value honestly.
Worked example
A client who commissions a $2,400 project three times a year and stays for three years, where each project costs $900 to deliver — your hours at cost, the tools it uses and the occasional subcontractor. Enter those numbers above and the calculator returns exactly this:
| Average project value | $2,400.00 |
| Cost to serve, per project | $900.00 |
| Profit per project | $1,500.00 |
| Projects across the relationship (3 a year × 3 years) | 9 |
| Gross lifetime value | $21,600.00 |
| Profit lifetime value | $13,500.00 |
| Gross value per year | $7,200.00 |
| Keeping them one extra year adds | $4,500.00 |
| Replacing them means winning | 9 projects |
| Verdict | A keeper |
Now the same shape at a different size: a client paying $5,000 a project, twice a year, for four years — but each project costs $3,600 to serve. The gross is bigger, $40,000, and the profit is smaller than the smaller client's: $11,200, a 28.0% margin. The verdict flips to positive but thin. Size is not value; the margin decides what the years are worth — which is why this page prints both numbers and reads the profit one.
How it works
- Gross and profit are both printed, because they answer different questions. Gross lifetime value is the revenue history — the size of the relationship, useful for comparing clients and for feeling the weight of losing one. Profit lifetime value subtracts what each project costs you to deliver, and it is the number decisions should run on: effort, attention and worry are spent from profit, not from revenue that mostly passes through you on its way to your hours and your subcontractors.
- The extra-year line is a retention budget. Keeping this client one more year adds a known amount of profit, and that figure is the ceiling for what keeping them is worth spending — in money, or in hours priced honestly. Anything under the ceiling that genuinely keeps them is rational arithmetic; anything above it is a gift, and gifts should be given knowingly. Read it as arithmetic, not as an instruction to spend: most retention costs an afternoon of attention, not a budget line.
- The years input is a guess — so run it twice. Nobody knows how long a client stays; budgets get cut, contacts change jobs, companies pivot. The lifespan you type is the optimistic reading by default, because it is yours. Run the calculator again with the years halved and read that profit figure as the floor. Decisions that still make sense at the floor — how much attention this client gets, how calmly you can take a quiet quarter from them — are the ones you can trust.
- Value and risk are different columns. The client with the highest lifetime value is very often the client whose departure would remove the largest share of your income — the same steady volume drives both numbers. This page prices the value; the client concentration checker measures the exposure. A keeper and a single point of failure can be the same client, and holding both facts at once is the whole discipline.
- Replacements rarely arrive cold. If the anchor client left, the nine projects that replace them would most likely come the way the last nine did: through people who already know your work. The referrals guide covers turning kept clients into the source of the next ones — which is the other half of why keeping them is worth the arithmetic above.
