Where people go wrong with freelance & self-employed numbers
The classic mistake is setting a rate equal to a salary divided by 2,080 hours, forgetting unbillable time, self-employment tax, insurance, retirement and unpaid vacation. Freelancers also miss quarterly estimated tax deadlines and pay penalties. Deductions have rules and record requirements, so treat the calculators as planning estimates and confirm with a tax professional. Bill for the hours you can sell. Set aside tax early.

Definitions
Freelance & Self-Employed terms
- Billable utilization : glossary term
- Billable hours divided by available working hours over the same period.
- Safe harbor : glossary term
- A payment threshold that can reduce estimated-tax underpayment exposure when current rules are met.
- Solo 401(k) : glossary term
- A 401(k) for a self-employed person or owner-only business. One person contributes as both employee and employer. That dual capacity is why it can exceed a SEP IRA at the same income.

Common freelance & self-employed questions
How do I set my freelance rate?
Start from the annual income you need, add self-employment obligations, health coverage, retirement contributions, paid time off, equipment and a margin for gaps between engagements, then divide by the hours you will realistically bill, which is substantially fewer than full-time hours.
What percentage of my income should I set aside for taxes?
Enough for income tax at your expected marginal rate plus self-employment obligations on net earnings plus any state liability. The combined figure varies widely by income and location, so compute it from your own numbers and move it at the moment each payment arrives.
Should I charge hourly or per project?
Project pricing is generally better once you can estimate the work, because it decouples income from hours and rewards efficiency , not penalising it. Hourly suits genuinely open-ended work. The prerequisite for project pricing is a written scope.
How do I handle scope creep?
Prevent it in the statement of work instead of managing it afterwards. Define what is included, what is explicitly excluded, how many revisions are covered and what triggers a change order. Unpaid extra work almost always originates in an ambiguous scope, not a difficult client.
What is a realistic billable percentage?
Considerably less than full capacity once sales, proposals, admin, invoicing, bookkeeping, marketing and learning are counted. Measure your own over a representative month , not estimating, because the measured figure is almost always lower than the assumption.
Should I form a company or work as a sole trader?
The trade-offs involve liability, tax treatment, administrative burden and how clients contract with you, and the right answer depends on jurisdiction, income level and risk exposure. It is one of the few freelance decisions genuinely worth professional advice.
How do I deal with late-paying clients?
Structurally instead of reactively: deposits before starting, milestone billing on longer engagements, clear terms on the invoice, and systematic follow-up before an invoice becomes overdue. For a freelancer, payment timing frequently matters more than headline rate.
When should I raise my rates?
When consistently booked, when the work has measurably improved, or when costs have risen. Raise for new clients first to establish the level with evidence, then move existing clients at a natural boundary with notice. Expect some attrition and check the higher rate compensates.
Solo 401(k) or SEP IRA for a self-employed retirement plan?
A solo 401(k) usually allows a larger contribution at the same income, because it lets you contribute as both employee and employer, while a SEP IRA only has an employer-side contribution. A SEP is simpler to administer. A solo 401(k) can also accept a loan and, depending on the provider, a Roth option.

Freelance & Self-Employed calculator questions
How do I set a freelance hourly rate?
Start from the income you need, add taxes, benefits and overhead, then divide by the hours you can realistically bill, not a full 2,080.
When are quarterly estimated taxes due?
Generally in April, June, September and January, and the safe harbor calculator shows the minimum to pay to avoid a penalty.
Is a 1099 job better than a W-2 job?
A 1099 rate must be higher to match a W-2 package, since you pay both halves of payroll tax and your own benefits.
