The rate on your invoice should come from a deliberate calculation, not a guess based on what feels reasonable to ask for. Here are three frameworks, and when each one applies.
Cost-plus: know your real number before you negotiate anything
Start by calculating what an hour of your time actually needs to cover: your target income, divided by billable hours only — not total working hours. A common mistake is dividing target income by 40 hours/week, ignoring that a meaningful chunk of any freelancer's time goes to admin, proposals, and non-billable work. If only 60–70% of your time is actually billable, your rate needs to account for that gap, plus overhead (software, insurance, taxes you cover yourself that an employer normally would). This is your floor — the number below which you're quietly losing money no matter how busy you are.
Market-rate: what are comparable people actually charging
Research rates for your specific skill level, niche, and region — general "freelance rate" surveys are too broad to be useful, but niche communities, job boards showing rate ranges, and direct conversations with peers give a much more accurate picture. Use this as a sanity check against your cost-plus number: if market rate is meaningfully higher than your floor, you have room to price toward the market instead of your minimum.
Value-based: pricing to the outcome, not the hours
For project work with a clear business outcome — a website expected to drive sales, a campaign with a revenue target — hourly framing can actually undersell you. If the work is worth $20,000 to the client's business, pricing based on your hourly rate times estimated hours may leave real money on the table. Value-based pricing means quoting based on the outcome's worth to the client, which requires understanding their business well enough to make that case credibly.
Build in room to raise rates later
Rates you set for a new client don't have to be permanent. A simple, low-friction approach: review rates annually, and give existing clients advance notice ("starting next quarter, my rate will be X") rather than surprising them on an invoice. Clients who value the relationship rarely leave over a reasonable, well-communicated increase — the ones who do were often underpaying for the value already.
Your invoice is where your rate becomes real. If the number makes you uncomfortable to send, that's a pricing problem, not an invoicing problem.
