#Why the salary-divided-by-2080 method fails
The instinct when going independent is to take the salary you want, divide by 2,080 working hours, and call that your rate. Someone targeting $85,000 arrives at roughly $41 an hour and undercharges by about 60%.
Four things break that arithmetic:
You do not work 2,080 billable hours. Between holiday, sick days, and the weeks between contracts, most freelancers work 44 to 48 weeks. Of those hours, only 55% to 65% are billable once sales calls, proposals, invoicing, admin, marketing and professional development are counted. New freelancers often start nearer 40%.
You pay both halves of payroll tax. In the US, self-employment tax is 15.3% on net earnings up to the Social Security wage base, because you are now both employer and employee. That is on top of income tax.
Your employer was buying things you now buy. Health insurance, hardware, software licences, professional liability insurance, accounting, coworking and training were all invisible line items in someone else's budget. They are now yours.
Nobody pays you to be sick, or to lose a client. Employment includes an implicit insurance policy against gaps. Self-employment does not, which is what the profit and risk buffer represents.
#How the calculation works
The model works backwards from what you want to keep:
1. Net needed = target take-home + retirement contribution
2. Profit needed = net needed / (1 − income tax − self-employment tax)
3. Revenue needed = (profit needed + business costs) × (1 + buffer)
4. Billable hours = working weeks × hours per week × utilisation
5. Minimum rate = revenue needed / billable hours
Step two is where most people go wrong. Grossing up for tax is not the same as subtracting tax — if your combined rate is 40%, you need $141,667 of profit to keep $85,000, not $119,000.
#Setting utilisation honestly
This input changes your rate more than any other. Track a normal week for a fortnight and count only the hours a client would actually accept on a timesheet. Most people are startled by the result.
Realistic bands:
- 40% to 50% — first year independent, or a practice with heavy sales and marketing effort
- 55% to 65% — established solo freelancer with steady referral flow
- 70%+ — usually only sustainable on long retainers, and often a sign you are neglecting business development, which shows up as a gap three months later
Setting this to 100% is the single largest cause of underpricing in independent work.
#From hourly to project pricing
The hourly figure this calculator produces is your floor — the point below which you are working at a loss relative to your goals. It is not the price you should quote.
Once you can scope reliably, fixed-fee pricing is better for both sides. The client gets budget certainty, and you capture the upside of working efficiently — which hourly billing actively penalises, since getting faster reduces your income.
To price a fixed fee: estimate the hours honestly, add 25% for scope you have not thought of, multiply by your floor rate, and then sanity-check the figure against the value of the outcome to the client. If a project will unlock $400,000 of revenue for them, a $28,000 fee is not expensive.
#Raising your rates
Review annually. The mechanics that work:
- Raise for new clients first. There is no risk, and it establishes the new number as normal.
- Give existing clients 60 days notice at a natural renewal point, in writing, without extensive justification. Confidence in the delivery matters more than the explanation.
- Expect to lose your most price-sensitive client. That is usually the correct outcome, and the capacity is more valuable elsewhere.
- A rate unchanged for three years has fallen 10% to 15% in real terms, before accounting for the fact that you are measurably better at the work.
#What the calculator does not include
- Payment terms and late payment. If clients routinely pay at 60 days, you need working capital. That is a cash flow issue rather than a rate issue, but it is real — the invoice generator covers terms that reduce it.
- Bad debt. Some invoices go unpaid. The buffer input is where this belongs; 5% is a reasonable starting point.
- Rate variation by work type. Rush work, weekend work, and work outside your core specialism should carry premiums. Use the floor as the base and price up from there.
