Most freelancers set their rate by guessing, looking at what competitors charge, or picking a number that feels comfortable. All three approaches leave money on the table. Your rate should be a math problem, not a mood. Here is how to calculate it, when to adjust it, and the exact language to use when you tell a client your price is going up.
The formula (with actual numbers)
Start with the annual salary you would earn doing similar work as a full-time employee. Look this up on the BLS wage data site for your occupation and region, or check Glassdoor and Levels.fyi for industry-specific ranges. Use the median, not the top of the range, as your baseline.
Say that number is $75,000. Now add the cost of benefits you are covering yourself. Health insurance premiums for a family plan through the marketplace average $1,200 to $1,800 per month depending on your state and coverage level. Call it $18,000 per year. Add retirement contributions you would have received from an employer match (roughly 3% to 6% of salary, so $2,250 to $4,500). Add your business overhead: software, equipment, internet, professional development. For most service-based freelancers, that is $3,000 to $6,000 annually.
Your adjusted annual target is now around $98,000 to $104,000. But you will not bill 2,080 hours a year like a salaried employee. After accounting for vacation, sick days, administrative time, and gaps between projects, most freelancers bill 1,200 to 1,500 hours annually. Divide $100,000 by 1,300 billable hours and your hourly rate should be around $77.
That number might feel high. It is not. It accounts for the 15.3% self-employment tax, the benefits you are funding, and the reality that you will not be billing every available hour. Charging $45 an hour because it "seems reasonable" on a $75,000-equivalent skill set means you are effectively earning $38,000 after taxes and expenses.
The tax math nobody explains clearly
As a freelancer, you pay both the employer and employee portions of Social Security and Medicare taxes. That is 15.3% on the first 92.35% of your net earnings, per IRS guidelines. On top of that, you owe federal and state income tax on your net profit.
A safe general rule: set aside 25% to 35% of every payment you receive. The exact percentage depends on your total household income, your state's tax rate, and your deductions. Someone in California with a working spouse will owe a different percentage than a single filer in Texas (which has no state income tax).
Quarterly estimated tax payments are due in April, June, September, and January. Miss a payment and the IRS charges penalties. Open a separate savings account, transfer your tax set-aside with every invoice payment, and do not touch it. The money in that account was never yours.
Why you are probably undercharging
Women freelancers earn roughly half what men earn from independent work, according to recent survey data. Some of that gap reflects industry distribution, but a significant portion comes from how rates are set. Women are more likely to anchor their rate to what feels "fair" rather than what the market supports, more likely to discount preemptively, and more likely to absorb scope changes without adjusting the price.
Here is a test. If every client you pitch says yes without hesitation, your rate is too low. A healthy close rate on proposals is 40% to 60%. If you are converting 90% of prospects, you have room to charge more. The clients who push back are not your clients. The ones who pay your rate without flinching are.
Raising your rate for new clients is simple. You quote the new number. No explanation needed, no apology, no discount for the first project. New clients have no baseline to compare against, so they either accept your rate or they do not. The ones who accept are usually better clients, because they value quality over bargain-hunting.
Raising rates with existing clients
This is the conversation freelancers dread, and most avoid it until resentment builds. But the mechanics are straightforward.
Timing matters. The best moments to raise your rate with an existing client: when their contract renews, when the scope of work has expanded, or when you have been working together for a year or more. Do not raise your rate in the middle of a difficult project or immediately after a mistake. Choose a moment when your value is fresh in their mind.
The script: "Starting [date, typically 30 days out], my rate for [type of work] will be [new rate]. I want to give you advance notice so we can plan accordingly. I have enjoyed working with you and look forward to continuing." That is the whole message. No justification, no apology, no negotiation opening. You are informing, not asking.
Most clients will accept without pushback, especially if the increase is reasonable (10% to 20%). Some will negotiate. A few will leave. The ones who leave over a 15% increase were paying you below market, and replacing them at your new rate is a net gain even if it takes a few weeks to fill the gap.
Project rates vs. hourly rates
Hourly billing rewards slow work. Project billing rewards efficiency. As you gain experience and complete tasks faster, hourly billing actually penalizes your expertise, because you finish in fewer hours and earn less for the same deliverable.
For well-defined deliverables (a website redesign, a quarterly report, a marketing strategy), project pricing is almost always better for the freelancer. Estimate the hours, multiply by your hourly rate, add a 15% to 20% buffer for revisions and scope adjustments, and quote the flat fee. The client gets price certainty. You get rewarded for working efficiently.
Keep hourly billing for ongoing, open-ended engagements where the scope shifts frequently: retainer-based consulting, weekly content creation, or project management support. In those cases, hourly billing protects you from absorbing unlimited work for a fixed price.
What to do this week
Pull up your last three months of invoices. Calculate your total revenue, subtract your business expenses, and divide by the total hours you worked (including unpaid administrative time). That number is your real effective hourly rate. Now compare it to the formula above. If there is a gap, you have a pricing problem, not an income problem. The fix is adjusting your rate, not working more hours.
