Build a freelance rate calculator that works back from the income you need
Most freelancers underprice because they divide a salary by 52 weeks and 40 hours. A freelance rate calculator works the other way: start from the income you need, add the costs an employer used to cover, take off holidays, admin and quiet weeks, and divide by the hours you can actually bill. Anticode can build that as a shareable tool for your own site, a community or a newsletter.
The working, step by step
- Target take-home income for the year.
- Add tax and social contributions. Rules vary by country and business structure, so the simplest honest version asks the user for an effective rate rather than computing it.
- Add business costs: software, equipment, insurance, accountant, coworking, training, pension contributions, and a buffer.
- Work out available days: 52 weeks × working days per week, minus holidays, public holidays and an allowance for sickness.
- Apply a billable share. Some of those days go on sales, admin, invoicing and learning. Many freelancers bill well under 100% of their working time; let the user set the share and show the effect.
- Divide the total needed by billable days for a day rate, and by billable hours for an hourly rate.
Showing each line of that working is the point. A single output number invites people to fiddle it down; a visible chain shows why the rate is what it is, and makes a good reference when they explain their prices to a client.
Making the inputs honest
- Utilisation slider
- The share of working time that's billable, with the hourly rate updating as it moves. This is usually the input with the biggest effect, and the one people are most optimistic about.
- Cost list
- An itemised list that totals itself, prefilled with common categories set to zero so nothing is forgotten.
- Days off
- Holiday, public holidays and sick days as separate fields. A default of zero sick days is a classic way to undercharge.
- Hours per day
- Defaults to the user's normal day, but billable hours should be fewer than hours at the desk.
- Currency
- A selector for the symbol only. The calculator doesn't convert anything.
Outputs worth adding
- Hourly, day and week rates side by side, rounded to sensible figures as well as exact.
- A sanity check: the equivalent annual salary at full-time hours, to show why a freelance rate looks high next to a job advert.
- Project pricing: estimated hours times rate, with a contingency percentage.
- Minimum viable rate versus target rate: the floor below which work loses money, and the figure to quote.
Ask for the user's last inputs to be saved in their browser so they can revisit them at the next price review. Nothing they enter is sent to you, which is the right default for income figures.
Describing it, and using it to find clients
"A what to charge calculator for freelance designers, for my newsletter's website. Inputs: target take-home, effective tax rate, itemised business costs, working days per week, holiday, public holidays, sick days, billable share. Show the full working as a list, then hourly, day and weekly rates, and a project estimate tool. Save inputs on the device. Friendly, plain design; one accent colour; British English."
If the tool is a way for people to discover you, add a short newsletter sign-up or contact form beside the result. Those forms are the one thing that leaves the app: they reach you by email and in your Anticode dashboard.

What it can't tell anyone
- Market rates. It can't look up what others charge; it has no live data. It tells someone what they need, not what the market pays.
- Exact tax. Tax depends on the country, the business structure and allowances. An effective rate entered by the user is an approximation; an accountant gives the real figure.
- Shared benchmarks. Results aren't pooled across users, so there's no "freelancers like you charge" comparison.
- Contract terms. Payment terms, late fees and deposits are outside its scope.
Questions people ask
Is a day rate calculator different from an hourly one?
Same working, different divisor. Many freelancers quote day rates to avoid clients counting minutes; the calculator can show both.
Can visitors save their result?
It's kept in their browser between visits. They can also print the page or copy the figures.
Can I collect anonymous rates to publish averages?
Not through the calculator, since nothing it computes leaves the browser. A contact form with extra fields could collect figures people choose to send you; the extra fields arrive as part of the message.
