How The Billable Rate Works
1Start With Need
Set the annual personal income you want the business to support. Add pension, savings and a cash buffer rather than treating them as leftovers.
2Add Costs
Business insurance, software, accounting, equipment, travel and professional fees have to be recovered through billable work.
3Cut To Billable Hours
Not every working hour can be sold. Sales calls, admin, training, finance, proposals and quiet weeks reduce utilisation.
4Round For Quotes
Round the hourly and day rates to a practical quote number, then check whether the market can support it.
What The Result Means
The headline result is the hourly rate needed to fund your target income, costs, tax reserve, pension and buffer across the billable hours available. The day rate multiplies that hourly result by the quoted day length. If your billable share is low, the required rate rises quickly because fewer hours must carry the whole business.
This calculator is useful before taking on work at a low rate. It shows the commercial rate required by your own cost base. It does not prove that clients will pay that amount, and it does not tell you whether a lower introductory rate is strategic. It gives you the floor from which a pricing decision can be made honestly.
Formula And Method
Required after-reserve income = target personal income + pension and savings target.
Pre-reserve income need = required after-reserve income / (1 – tax reserve percentage).
Revenue required before buffer = pre-reserve income need + business costs.
Revenue required = revenue required before buffer x (1 + profit buffer percentage).
Billable hours per year = working weeks x working hours per week x billable share.
Required hourly rate = revenue required / billable hours per year.
Required day rate = required hourly rate x quoted day length.
Worked Billable Rate Examples
New Freelancer
A new freelancer targeting GBP 42,000 with 55% billable time may need a higher hourly rate than expected because learning, marketing and admin consume time.
Senior Specialist
A senior consultant with high costs but strong pricing power may choose fewer billable weeks and a larger buffer. The rate should reflect availability and expertise.
Quiet Pipeline
If billable time falls from 70% to 45%, the required rate jumps. That can indicate a need for sales work, retainers or a lower cost base.
Rate Planning Checks
| Check | Question | Rate Impact |
|---|---|---|
| Utilisation | How much time is truly billable? | Lower utilisation raises the hourly rate. |
| Scope | Does the rate cover meetings, prep and follow-up? | Hidden scope lowers effective pay. |
| Payment terms | How long until invoices are paid? | Late payment increases cash reserve needs. |
| Specialism | Is the work scarce, urgent or high risk? | Specialist work can support a higher margin. |
| Repeat work | Will the client book predictable time? | Retainers may justify a different rate structure. |
When To Recalculate
Recalculate after a quiet quarter, a new software subscription, a move from sole trader to limited company, a change in childcare or caring hours, or a shift from hourly work to fixed project work. Rates should reflect the business you are actually running, not the rate you started with years ago.
If the required rate is far above what clients will pay, do not simply ignore the result. Consider a narrower offer, higher-value clients, packaged services, lower overheads, more billable days, or a salary role. A rate that cannot fund the business is not sustainable.
Rate Floor Versus Client Price
The calculated hourly rate is best treated as a floor, not the final client price. A floor tells you the lowest sustainable rate for the business model entered. A market price may sit above it because the work is urgent, specialist, regulated, commercially sensitive or hard for the client to do in house. It may sit below it if the client buys predictable volume, accepts a narrower scope, pays quickly or removes risk from the engagement.
Keep two numbers in your records: the internal floor and the quote you send. If a client asks for a discount, reduce the client price only after checking whether the new figure still clears the floor. If a retainer lowers sales time and improves cash flow, rerun the calculator with higher billable share rather than applying a random discount. This result is unique because it ties the rate to your target income, utilisation, costs, tax reserve and buffer, then translates that into both hourly and day-rate terms.
FAQ
What billable percentage should I use?
Many freelancers test 50%, 60% and 70% to see the sensitivity. New businesses often have lower billable time.
Does this include VAT?
No. Add VAT handling separately if registered. VAT collected is not income in the same way as fees.
Is the tax reserve exact?
No. It is only a planning reserve. Actual tax depends on structure, income, region and reliefs.
Should I include unpaid holiday?
Yes. Reduce working weeks or billable share so holiday is reflected.
Can I use this for day rates?
Yes. The day rate line multiplies required hourly rate by the quoted day length.
What if my market rate is lower?
Review costs, target income, utilisation and offer positioning before accepting long-term underpricing.
