What this result does not account for
- Results are a model, not a quotation — an institution's own figures govern.
- Every input is an assumption; change one and the answer changes with it.
- Rounding is applied only at the display layer, so totals may differ by a cent from a statement that rounds each line.
In short: Swapping a $100,000 salary for $100,000 of 1099 income costs you $1,478.55 in net pay, so you need $102,126.99 to break even — a 2.13% premium on tax alone. Replace $12,000 of benefits and 15 days of PTO and the true requirement jumps to $119,896.22, a 19.90% premium.
Formula
The break-even gross is solved by bisection: the contractor gross whose net pay exactly matches the employee's. PTO is valued at the daily salary rate across 260 working days.
Worked Example
- Compute the employee's net pay. $100,000 less $7,650 of FICA and $13,841 of income tax leaves $78,509.
- Compute the contractor's net on identical gross. SE tax of $14,129.55 is far higher, but a $15,667.05 QBI deduction cuts income tax to $8,840, leaving $77,030.45.
- Measure the gap. $1,478.55 — much smaller than the $6,479.55 of extra payroll tax, because QBI hands back $5,001 of it.
- Solve for the break-even gross. $102,126.99 matches the employee's net pay exactly: a 2.13% premium on tax grounds alone.
- Add what the employer was providing. $12,000 of benefits and 15 days of PTO worth $5,769.23 push the true requirement to $119,896.22 — a 19.90% premium.
The widely repeated advice to 'add 30% because of self-employment tax' is wrong twice over. The tax gap is only 2.13% once QBI is counted, but the benefits gap is far larger than most contractors allow for. The total lands near 20% for entirely different reasons.
Strengths & Limits Of This Model
Where this engine is strong
- Runs entirely in your browser — no figure you type is transmitted or stored.
- Shows the full working, so every number can be traced and challenged.
- Free, unmetered and free of affiliate incentives.
Where it stops
- Generalised assumptions cannot capture every individual circumstance.
- Jurisdiction-specific rules and mid-year changes may not be reflected.
- A model output is not a substitute for a professional review of your position.
Practical Use Cases
Negotiating a contract rate
Take your target salary, run it through this tool, and quote the resulting hourly figure. It is defensible line by line in a negotiation.
Evaluating a contract-to-permanent offer
Convert the contract rate back to a salary equivalent before comparing. A $60 hourly rate is not a $124,800 salary once benefits are stripped out.
Deciding whether to leave employment
Model the tax and benefit side here, then check the cash-flow implications with the Freelance Tax Calculator.
Pricing part-year or reduced-hours work
Fewer billable hours means the same annual requirement spread across a smaller base, so the hourly rate rises sharply below about 1,800 hours.
Methodology & Editorial Standards
The employee side applies the 7.65% employee share of FICA and taxes salary less the standard deduction. The contractor side applies self-employment tax to 92.35% of profit, deducts the employer-equivalent half, and allows the 20% QBI deduction that a W-2 employee cannot claim — an asymmetry that closes most of the apparent gap. The break-even gross is found by 200-iteration bisection on net pay. Paid time off is valued at the daily salary rate over 260 working days, which slightly overstates value if your contract rate already assumes unpaid gaps. Employer retirement matching should be entered within the benefits figure. Unemployment insurance, workers' compensation, professional liability cover and the cost of unpaid gaps between contracts are not modelled and all favour the employee. The engine implements the standard published formula for this calculation. Inputs are validated for domain and sign before evaluation, and any undefined case returns an em-dash rather than a spurious value.
Computation runs in IEEE-754 double precision at full internal precision; rounding to two decimal places occurs strictly at the display layer, so no cumulative drift enters the result. All monetary outputs use accounting presentation — grouped thousands, two decimals, negatives in parentheses — so figures can be transcribed directly into a model or working paper. Division-by-zero and out-of-domain inputs return an em-dash rather than a misleading number.

1099 Tax Calculator — 20 Expert FAQs
20 analyst-written answers to the questions practitioners actually ask — optimised for voice and answer-engine retrieval.
How much more should a 1099 contractor charge than a W-2 salary?
About 20% in total — but only 2.13% of that is tax. The rest replaces benefits and paid time off the employer was providing.
Do 1099 contractors really pay 15.3% more tax?
No. The extra payroll tax is $6,479.55 here, but the QBI deduction hands back $5,001 of it, leaving a net gap of just $1,478.55.
What hourly rate matches a $100,000 salary?
$57.64 an hour across 2,080 billable hours, against the $48.08 nominal employee rate. Fewer billable hours pushes the required rate higher.
Why do contractors pay both halves of FICA?
Because there is no employer to pay the other half. Self-employment tax is simply both halves combined, applied to 92.35% of net profit.
Can a 1099 contractor claim the QBI deduction?
Yes, and it is the single biggest offset. A W-2 employee cannot claim it at all, which is why the tax gap is far smaller than the payroll tax difference suggests.
How do I value employer benefits?
Add health insurance premiums the employer paid, retirement matching, and any other funded benefit. $12,000 is typical for a mid-level role.
Is paid time off really part of my rate?
Yes. Fifteen days is $5,769.23 of paid salary you simply do not receive as a contractor. It has to come out of your billable hours.
What about gaps between contracts?
Not modelled here, and they favour employment substantially. Many contractors target 1,800 billable hours rather than 2,080 for exactly this reason.
Do I need to make quarterly estimated payments as a 1099?
Yes, once you expect to owe $1,000 or more. There is no withholding, so the obligation falls entirely on you.
Can I deduct expenses as a contractor?
Yes, and that is a genuine advantage. Business expenses reduce profit before both SE tax and income tax, which a W-2 employee cannot do at all.
Is 1099 income better for retirement saving?
Often. A solo 401(k) allows both employee and employer contributions, with far higher limits than a typical workplace plan.
What is the difference between 1099-NEC and 1099-MISC?
1099-NEC reports non-employee compensation for services, which is what most contractors receive. 1099-MISC now covers rents, prizes and other payments.
Should I form an LLC as a contractor?
It provides liability separation but changes nothing about tax by default. The tax question is whether to elect S-corp treatment, which matters above roughly $60,000 of profit.
Am I legally allowed to be a 1099 for this work?
It depends on control, not preference. If the client sets your hours, supplies your tools and directs how you work, the classification may be wrong regardless of what the contract says.
Does the premium change at higher salaries?
Yes. Above the Social Security wage base of $168,600 the extra payroll tax largely disappears, so the tax premium narrows considerably while the benefits premium stays.
Is this 1099 tax calculator free to use?
Yes. It is free, requires no account, and has no usage limits. ApexConverter is funded by contextual advertising, never by selling user data.
Is my data sent to a server?
No. The engine runs as Vanilla JavaScript inside your browser under our Zero-Server Client-Side Execution model. Your figures are computed locally and are never transmitted, logged, or stored.
How accurate is this calculator?
It applies the standard closed-form formula in IEEE-754 double precision, rounding only at the display layer. The engine is reconciled against an independent reference implementation before release.
Does it work on mobile?
Yes. The interface is mobile-first with numeric keypad hints and is tested down to a 320-pixel viewport with no horizontal scrolling.
Can I use it offline?
Largely, yes. Because computation is client-side, the page continues to calculate without a network connection once it has loaded.
