How to Set Your Day Rate as a New Limited Company Contractor

Setting Your Day Rate as a New Limited Company Contractor

Choosing the right day rate is one of the most important decisions you will make when starting out as a limited company contractor. Set it too low and you will undercut your own business; set it too high without justification and you risk losing contracts. This guide walks through a practical, step-by-step approach to pricing your services correctly from day one.

Start With What You Actually Need to Take Home

The most reliable starting point is your required net income. Work out the monthly take-home pay that covers your mortgage or rent, household bills, food, and personal savings. Once you have that figure, work backwards to calculate the gross income your limited company must generate to deliver it, accounting for corporation tax, dividend tax, and any salary you draw.

This reverse-engineering approach anchors your pricing in financial reality rather than guesswork.

Account for Billable Days, Not Calendar Days

A common mistake among new contractors is dividing their target annual income by 365 or even 260. In practice, industry guidance suggests around 222 billable days per year as a realistic figure for UK contractors. That accounts for:

• 25 days annual leave
• 8 bank holidays
• Gaps between contracts
• Sick days and contingency

If your annual gross income target is, say, £80,000, dividing by 222 gives you a baseline day rate of approximately £360. That is your floor before overheads.

Layer in Your Overheads

Running a limited company carries costs that a permanent employee never sees. Every one of these must be factored into your day rate:

• Accountancy fees - a contractor accountant typically costs £100-£150 per month
• Professional indemnity and public liability insurance
• Software subscriptions - accounting software, productivity tools, sector-specific licences
• Training and CPD - essential for keeping your skills marketable
• Pension contributions - no employer will top up your pot
• Marketing costs - your website, LinkedIn Premium, or CV services
• Contingency reserve - aim for three to six months of operating costs to cover unexpected downtime

Add these annual overhead costs to your gross income target, then recalculate against your 222 billable days.

Apply the Permanent-to-Contractor Uplift

If you know your equivalent permanent salary, a useful cross-check is to convert it to a daily rate and apply an uplift. Guidance from contractor specialists recommends a 20-30% uplift over your permanent equivalent to offset lost benefits such as paid holidays, employer pension contributions, sick pay, and employment rights protections. Some practitioners suggest multiplying your permanent hourly rate by 1.5 to 2x when converting to a contract day rate.

This uplift is not greed. It is the commercial reality of running your own business without a safety net.

Benchmark Against the Market

Your calculations mean little if the market will not support your rate. Research published in 2025 indicates the following approximate outside IR35 day rate ranges across key sectors:

• IT and Technology: £400-£800 per day
• Finance: £350-£700 per day
• Engineering: £300-£600 per day

Rates vary significantly by location, seniority, specialism, and client size. London and the South East consistently attract premiums. Use job boards, sector reports, and conversations with recruiters to triangulate where your skills sit within these bands.

Understand How IR35 Status Affects Your Rate

IR35 status has a direct and significant impact on the day rate you should accept. The client determines their IR35 position via a Status Determination Statement (SDS); you cannot and should not treat any listing's claimed status as verified by this platform or anyone other than the end client.

Where the client states a role is outside IR35 and engages you through your limited company, you retain the tax efficiencies of the contractor model. That typically means you can accept a lower headline day rate (say, £550 per day) and still take home more than on an inside IR35 engagement at a higher rate (say, £650 per day), because inside IR35 requires PAYE deductions and employer National Insurance contributions are effectively absorbed by the contractor.

For a detailed explanation of how inside and outside IR35 rates compare, see the HMRC guidance on off-payroll working.

When reviewing any contract, consider:

• The client's stated IR35 determination and the basis for it
• Whether substitution rights are genuine and documented
• The degree of control the client exercises over how you work
• Whether the rate reflects the IR35 risk you are accepting

Work With Agencies, Not Around Them

If you are sourcing roles through a recruitment agency, use them as a source of market intelligence. Agencies have visibility of what comparable contractors earn and can negotiate on your behalf. Share your rate research openly and ask them to confirm whether your expectations are realistic for the specific role, client, and location.

Do not anchor on a number before speaking to an agent. Their market knowledge can save you from pricing yourself out or leaving money on the table.

Review Your Rate Regularly

A day rate is not set once and forgotten. Review it at least annually and at each contract renewal. Consider increases when you gain new certifications, move into higher-demand specialisms, or when market rates shift. Rates across most sectors rose 20-30% between 2023 and 2024, so staying current with benchmarks protects your earnings over time.

Summary Checklist

• Calculate required net income and work backwards to a gross figure
• Divide by 222 realistic billable days, not total working days
• Add all overhead costs to your annual target
• Apply a 20-30% uplift over your permanent salary equivalent
• Benchmark against current market rates for your sector and location
• Factor in the IR35 status the client claims and its impact on take-home pay
• Discuss your rate with agencies and revisit it at least once a year
