The freelance year-end review: numbers worth tracking

December arrives. You have a rough sense of whether the year was good or bad. Maybe you know the total revenue. Probably not much else.

That’s the standard freelance year-end: a feeling, not a number.

The problem with feelings is they don’t compound. You can’t improve a vague impression year over year. You can improve a number.

Here are the four numbers that tell you what actually happened this year — and what to change next year.

Number 1: Your effective hourly rate

Not your headline rate. Your effective rate.

Take your total annual revenue. Divide it by your total hours worked — including admin, prospecting, revision rounds, coordination calls, everything. That’s your effective rate.

For most freelancers, this number is lower than expected. If you charge €80/hour but spend 35% of your time on non-billable work, your effective rate is €52/hour. That’s what your time actually cost this year.

If you tracked your calendar events consistently, this calculation takes 20 minutes. If you didn’t, this year’s effective rate is your best argument for starting next year.

Number 2: Your billability ratio

Billable hours divided by total working hours. Expressed as a percentage.

Experienced solo freelancers typically operate at 70 to 80%. Below 60% is a signal that overhead is too high or that rates aren’t absorbing it. Above 85% usually means you’re not investing enough time in business development.

If you know your billability ratio, you know whether the lever for next year is higher rates, lower overhead, or more clients. Each has a different plan. Without the ratio, you’re guessing.

Number 3: Revenue per client

Sort your clients by total revenue this year. Not hourly rate — total revenue from the relationship.

The top two or three clients likely account for 60 to 70% of your annual revenue. That concentration is worth knowing: it tells you how much risk sits in any single client relationship ending.

Then look at the bottom of the list. What was the smallest client’s revenue? Divide that by the estimated hours you spent on the relationship. What was the effective rate? Small clients at low effective rates are the first candidates for dropping or repricing next year.

Number 4: Your average client lifespan

How many clients did you work with this year? How many were repeat clients from last year? How many were new?

A freelance business with mostly repeat clients compounds differently than one that replaces all its clients every year. Repeat clients cost zero acquisition time. New clients cost proposals, pitches, onboarding.

If you’re replacing most of your client base annually, your acquisition cost is embedded in every project. If you retain clients year over year, that time goes toward billable work instead.

You don’t need a CRM to track this. A simple spreadsheet with client name, start date, and last project date tells you everything.

What to do with the numbers

The review is only useful if it changes something.

If your effective rate is below €50/hour: raise rates on existing clients before taking on new ones. Expanding client count at a low effective rate just multiplies the problem.

If your billability ratio is below 60%: audit your overhead before acquiring clients. More clients at 55% billability means more overhead, not more revenue.

If one client represents more than 40% of revenue: either grow that relationship intentionally or reduce concentration by adding a comparable client. Single-client dependency is a business risk.

If your average client lifespan is less than one project: your acquisition cost is too high to sustain growth. Focus on retention and expansion before new business.

The 30-minute review

Pull your calendar for the year. Tag all client events if you haven’t already. Export or count the hours by client. Add up total working hours.

That’s the effective rate and billability ratio.

Add up revenue per client from your invoices.

Count how many clients were new this year versus returning.

Thirty minutes. Four numbers. A plan for next year that isn’t based on a feeling.

Your calendar already has the data. The review is just the question you ask of it once a year.

Timescanner shows your total hours per client and per period directly from your calendar events. Run your year-end review without rebuilding data from scratch. Works with any iCal-compatible calendar.
