What is the billable hours calculator?

A billable hours calculator separates the hours you work from the hours anyone pays you for. Utilisation — the share of your working week that ends up on an invoice — is the number that explains why a busy freelancer can still be underpaid. Someone working a genuine forty-hour week, spending six hours on admin and five on pitching, is billing twenty-nine. That is 72% utilisation, which is good. Many people are nearer 55%. The gap is not laziness; it is the unpaid half of running a business, and the only place it can be recovered is in the rate. This tool shows the weekly figure, the annual figure, and what the unbilled time is actually costing you.

How our free billable hours calculator works

1

Enter your real working week

The hours you genuinely work, not the hours you intend to.

2

Take out admin and email

Invoicing, bookkeeping, inbox, scheduling — necessary, unpaid.

3

Take out pitching

Proposals, calls, quotes that never became projects. Real hours, no invoice.

4

See the rest

Billable hours a week and a year, your utilisation rate, and the revenue that supports.

What can you use the billable hours calculator for?

Working out why money is tight

If income is short but the week is full, utilisation is usually the answer.

Justifying a rate rise

Unbilled hours a year is a concrete number to take into a rate conversation with yourself.

Deciding what to delegate

Once admin has an hourly cost attached, paying someone else to do it becomes a straightforward sum.

Who uses our free billable hours calculator?

Freelancers

Understanding why a full week does not produce a full week of income.

Consultants

Utilisation is the standard measure of whether a practice is working.

Agency owners

Tracking utilisation per person is how you spot a team member drowning in admin.

Anyone considering going freelance

Seeing the unpaid hours before committing, not after.

Why use the billable hours calculator?

Names the hidden cost

Puts a number on the hours nobody invoices for.

Realistic revenue

Annual income based on billable hours, not on a hopeful 40-hour week.

A benchmark

Tells you where your utilisation sits against what is normal and sustainable.

Tips for getting the best results

Track a real week first

Estimate and you will be wrong in a flattering direction. Track once and use the real number.

60–70% is normal

Above 75% rarely lasts and usually means no time is going into finding the next project.

Count the free calls

A 45-minute 'quick chat' with a prospect is pitching, not billable work.

Utilisation is a rate problem

You cannot get to 100%. The fix is to price so that 65% covers what you need.

Frequently asked questions

What is a good utilisation rate?

For an independent freelancer, 60–70% is realistic and healthy. Consultancies often target 70–80% for staff who do not sell. Consistently above 80% usually means business development has stopped, which shows up as a gap three months later.

Are meetings billable?

Client meetings on a live project usually are, and should be on the invoice. Sales calls and discovery chats with prospects are not, and they belong in the pitching line here.

Should I count training and learning?

As unbilled time, yes — it is real and it comes out of the same week. Add it to admin if you want the honest picture.

How does this change my rate?

Directly. If utilisation drops from 70% to 55%, you need roughly 27% more per hour to earn the same. The freelance rate calculator does that sum.
