How to Calculate Your Freelance Rate

Last updated: May 2026

Why most freelancers undercharge

The most common pricing mistake is not setting a number too low on purpose. It is setting a number without knowing what it needs to cover. Freelancers look at what others charge, pick something similar, and assume the math works out. Sometimes it does. Often it does not, because their cost structure, utilization, and tax situation are different.

Market rates are useful as a sanity check at the end of this process. They are not a useful starting point, because a competitor's rate says nothing about their expenses, their billable hours, or whether their business is actually sustainable. Build from your own numbers first.

The core formula

The method is straightforward. What makes it powerful is treating each input honestly rather than optimistically.

Step-by-step: each input explained

1. Annual personal income target

This is the net income you need to live on — after tax, after business costs. Include rent or mortgage, food, bills, transport, insurance, subscriptions, savings, pension contributions, and a buffer for unexpected personal expenses. Be honest. Freelancers who understate this end up subsidising their business with their quality of life.

If you are transitioning from employment, your target might match your previous take-home pay. If you are growing an established practice, it might be higher. There is no right answer, but there is an honest one.

2. Annual business expenses

List every cost your freelance business requires to operate: software subscriptions, hardware replacement cycles, professional insurance, accounting and bookkeeping fees, website hosting, domain names, marketing spend, professional memberships, training, and any workspace costs. Add these up annually. They are not optional extras — they are part of the cost of delivering work.

Freelancers who skip this step often find themselves paying business costs from personal income, which effectively shrinks their take-home without them realising it.

3. Tax reserve

Unlike employment, freelancers pay tax on profit rather than having it deducted at source. You need to set money aside from every payment received so that when tax is due, the money exists. The reserve percentage varies by country, income level, and entity structure — but a conservative planning range of 25–35% is common for most English-speaking markets. See the Tax Reserve Guide for a more detailed breakdown by region.

In the rate calculation, you are grossing up your income target to account for the tax you will owe. If you need £50,000 net and your effective tax rate is 30%, you need to earn approximately £71,400 gross.

4. Billable hours (the most important input)

This is where most freelancers make their biggest error. Not every working hour is a billable hour. Time spent on emails, proposals, admin, invoicing, marketing, business development, training, and non-billable project overhead does not generate revenue. If you assume 100% of your working time is billable, you will systematically underprice your work.

A realistic utilization rate for most freelancers falls between 60% and 75%. That means if you work 8 hours a day, 5 days a week, you might bill 5–6 of those hours. The rest goes into running the business.

To calculate annual billable hours: start with working weeks per year (typically 48, accounting for holidays and sick time), multiply by working days per week, multiply by daily hours, then apply your utilization rate.

Worked example in full

Let us walk through a complete calculation to see how the inputs interact.

This is the minimum rate — the floor below which the business does not cover its costs. Add a commercial buffer of 15–25% before quoting: a minimum of £55.77/hr becomes a quoted rate of £64–£70/hr. The buffer absorbs projects that run slightly over, slow periods, and room to negotiate without going below break-even.

Setting your buffer above minimum

Your minimum rate is a survival number. Your quoted rate needs to be a business number. The difference between the two is your operating margin — the space that covers uncertainty, reinvestment, and the projects that quietly cost more than they look.

A minimum buffer of 15% is prudent. 25% gives you more room for slower periods and selective client decisions. If every prospect says yes without hesitation, your buffer may be too small or your rate may be below what the market will support.

Different project types may justify different buffers: urgent projects, highly specialist work, or engagements with significant revision risk should sit at the higher end. Recurring, well-defined work from reliable clients can sit lower.

When to recalculate

Set a calendar reminder at least once per year. Also recalculate when any of the following change materially:

• Your personal living costs increase (rent, mortgage, dependents)
• Business costs grow significantly (new tools, insurance, premises)
• Your utilization changes — either you are billing more or less than your estimate
• Tax rules change in your jurisdiction
• You shift service mix from hourly to project or vice versa
• You consistently get accepted at first quote with no negotiation (rate likely too low)

Common mistakes

• Assuming all time is billable. It is not. Build the non-billable overhead into your utilization assumption, not your rate directly.
• Using headline tax rates. Effective tax rates are lower than headline rates because of deductions, allowances, and stepped rates. Use a realistic blended reserve rather than the top rate.
• Treating your minimum as your quote. The minimum is a floor. Quote above it.
• Copying a competitor's rate. Their cost structure, utilization, client mix, and margin targets are all different from yours.
• Never updating the calculation. A rate set in year one using year-one assumptions will not stay accurate as costs, capacity, and tax change.
