Freelance Day Rate Calculator

Divide your target annual salary (plus any overheads like pension, insurance and sick pay provision) by the number of working days per year. For example, 46 working weeks at 5 days per week gives 230 working days. A £50,000 salary would need roughly £217/day before overheads.

Most UK contractors assume 46 working weeks per year, accounting for 28 days statutory holiday (5.6 weeks) plus a small buffer for gaps between contracts. Some contractors work as few as 40 weeks; others manage 48-50.

If you are inside IR35, the end client or agency deducts PAYE tax and National Insurance from your fee, meaning your take-home is significantly lower. Outside IR35, you pay yourself via dividends through a limited company, which is more tax-efficient. Inside IR35 contractors typically need a 30-40% higher gross day rate to achieve the same net income.

Yes. As a contractor, you do not receive paid holiday. You should factor in the cost of 28 days (5.6 weeks) unpaid leave by dividing your target annual income over fewer working days. This effectively increases your required day rate.

Most freelancers need Professional Indemnity Insurance (required by many clients), Public Liability Insurance if working on client premises, and optionally Employers Liability Insurance if operating via a limited company. Combined policies typically cost £1,000-£2,000 per year depending on your profession and coverage level.

Outside IR35: pay yourself a small salary (usually around £12,570) and take the rest as dividends. Inside IR35: your fee is subject to PAYE. In both cases, deduct corporation tax (25%), employer NI (if inside IR35), pension contributions, insurance and accountancy fees to estimate your actual take-home.

UK software developer day rates typically range from £350-£500 for mid-level, £500-£700 for senior, and £700-£1,000+ for specialist or lead roles. London rates are 15-25% higher. Inside IR35 roles tend to offer higher gross rates to compensate for the tax burden.

As a limited company contractor, pension contributions are tax-deductible for your company and not subject to corporation tax. Adding 3-8% of your earnings as pension is strongly recommended. This effectively increases the gross rate you need to charge clients.

Review your day rate at least annually or whenever renewing a contract. Factor in inflation (typically 2-4%), any new skills or certifications, changes in market demand, and increases in your business costs such as insurance premiums or accountancy fees.

A day rate assumes a standard working day (typically 7.5-8 hours). Hourly rates give more flexibility and are common for part-day or irregular work. To convert, divide your day rate by your standard hours. For example, a £500 day rate at 8 hours equals £62.50/hour.
