Freelance Rate Calculator: How to Find Your Minimum Hourly Rate

Most freelancers pick a rate by looking around. What do others charge? What did the last client accept? That tells you what the market might pay. It doesn't tell you what you need.

This guide does the other half. You'll work out the lowest rate that still covers your life, your costs and your tax. Then you'll check every quote against it.

You need four numbers and about 20 minutes. A pen works. A spreadsheet is faster.

Not tax or legal advice. Everything below is an estimate and a plan, not a promise of income.

Why a minimum rate matters

A minimum rate is a floor, not a price tag. You can charge more. You just shouldn't go below it without knowing.

Without a floor, two things happen:

  • You say yes to a project that feels fine, and it quietly pays less than your rent needs.
  • You forget the hours nobody pays for. Emails. Invoicing. Finding the next client.

A floor turns "does this feel OK?" into "is this above my number?" That's an easier question at 11 pm with a client waiting.

Step 1: Decide what you want to take home

Start with your life, not your work. What do you need to pay yourself each month?

Add up rent, food, transport, insurance, debt payments and savings. Be honest. This is your target monthly pay.

Step 2: Add your business costs

Next, list what the business costs per month. Software. Equipment spread over its life. Phone. Accountant. Training. Fees.

This is your monthly business costs. Clients pay for these too, through your rate.

Step 3: Plan for tax

Your rate also has to cover tax. The share depends on where you live, your income and your setup. Nobody can give you one number that fits everyone.

So use an estimate. If you don't have one yet, the free Tax Reserve Calculator helps you work out how much to set aside from each payment: Get the free Tax Reserve Calculator

Check your estimate with a local accountant or your tax authority's guidance.

Step 4: Count your real billable hours

This is where most rates go wrong. You don't bill 40 hours a week, 52 weeks a year.

Take out:

  • Holidays and public holidays
  • Sick days
  • Admin, sales and invoicing time
  • Quiet weeks between projects

What's left is your billable hours per month. It's usually far lower than it feels.

Step 5: Do the maths

Here is the formula:

Minimum hourly rate = (target monthly pay + monthly business costs + tax reserve) ÷ billable hours per month

Then add a buffer. Clients pay late. Projects run over. A buffer keeps one bad month from becoming a crisis.

Worked example (example numbers only)

These numbers are made up to show the method. They are not typical, recommended or real figures. Use your own.

Item Example
Target monthly pay $3,000
Monthly business costs $400
Tax reserve (example rate: 25% of pay + costs) $850
Total needed per month $4,250
Billable hours per month (example) 85
Minimum hourly rate $50.00
Buffer (example: 15%) +$7.50
Minimum rate with buffer $57.50

How we got 85 hours in this example: 4 weeks × 5 days × 6 working hours = 120 hours. About 35 of those go to admin, sales and gaps. That leaves 85 billable.

The tax line here is a simple example: 25% of $3,400. Your real tax may work differently. That's why Step 3 says to use your own estimate.

From hourly to day and monthly rates

Once you have the hourly floor, the rest is simple:

  • Day rate = minimum rate with buffer × billable hours in a day. Example: $57.50 × 6 = $345.
  • Monthly retainer floor = minimum rate with buffer × hours the retainer covers. Example: 20 hours × $57.50 = $1,150.

Round up, not down.

Step 6: Check every quote against your minimum

A rate is only useful if you use it when you quote. Fixed-price projects are where the floor gets lost.

Say a client offers $1,200 for a website update. Sounds fine. Now estimate the hours:

Task (example) Estimated hours
Kick-off call and brief 2
Design changes 8
Build and testing 10
Two rounds of revisions 4
Total 24

$1,200 ÷ 24 hours = $50 per hour. In this example, that's below the $57.50 floor. To meet it, the quote would need to be at least 24 × $57.50 = $1,380.

Now you have options. Raise the price. Cut the scope. Or accept it on purpose, knowing the gap. Any of these is fine. Not knowing is the problem.

Things that quietly lower your real rate

  • Unlimited revisions
  • Rush jobs with no rush fee
  • Discounts without a reason
  • No deposit, then a late payment

Put these on paper before you send the quote.

When to recalculate

Run the numbers again when:

  • Your costs change (new software, new equipment, moving)
  • Your tax estimate changes
  • You notice your billable hours are lower than you planned
  • Once a year, as a habit

Do it faster with a spreadsheet

You can do all of this by hand. If you'd rather not, here are two tools I built for exactly this.

FAQ

What's a good freelance hourly rate?

There isn't one number. A good rate is one that covers your pay, costs and tax at the hours you can really bill, plus a buffer. Work out your floor first. Then look at what your market pays and price at or above it.

Should I quote hourly or a fixed price?

Either can work. Fixed prices are fine as long as you estimate the hours and check the total against your minimum rate. If the hours are very unclear, quote hourly or split the work into phases.

How much buffer should I add?

That's your call. The 15% above is only an example. If your income swings a lot, or clients often pay late, a bigger buffer gives you more room.

Does this tell me how much tax I'll owe?

No. It uses your own tax estimate to plan a rate. For what you'll actually owe, check with an accountant or your tax authority. Not tax or legal advice.
