About UK Salary Calculator

Who We Are

UK Salary Calculator is an independent, free-to-use resource dedicated to helping UK workers understand their pay. We are not affiliated with HMRC, the UK Government, or any financial institution. We are a small team of developers and finance professionals who believe that understanding your tax and take-home pay shouldn't require a degree in accountancy.

We built this tool because we were frustrated with overly complicated, ad-laden, or inaccurate salary calculators. Our goal is simple: give you a fast, reliable answer to "how much will I actually take home?" — without paywalls, sign-ups, or confusing jargon.

What We Offer

We provide a comprehensive suite of free calculators covering every aspect of UK taxation and personal finance:

• Contractor Calculator — See your net pay as a limited company contractor, including corporation tax, salary and dividend split, and IR35 comparisons.
• IR35 Calculator — Compare your take-home pay inside vs outside IR35, helping contractors understand the financial impact of their employment status determination.

Our Data Sources

Accuracy matters. All our tax calculations are based on official, publicly available data from:

• HMRC (His Majesty's Revenue & Customs) — income tax rates, NI thresholds, tax bands, and guidance
• GOV.UK — official student loan repayment thresholds, pension auto-enrolment rules, and employment legislation
• Office for Budget Responsibility (OBR) — tax policy forecasts and economic data
• Scottish Government — Scottish income tax bands set independently by the Scottish Parliament
• NHS and WHO — clinical formulas used in our health calculators (BMI, calorie needs, body fat assessment)

We update our calculators promptly at the start of each new tax year (6 April) to reflect any changes announced in the UK Budget. All rates shown are for the 2025/26 tax year (6 April 2025 – 5 April 2026) unless otherwise stated.

A Note on Accuracy

Our calculators provide accurate estimates for the majority of employed workers in standard tax situations. However, individual tax circumstances can vary significantly. Factors that may affect your actual take-home pay include: benefits in kind, non-standard tax codes, multiple income sources, Marriage Allowance, blind person's allowance, and others.

Our calculators are for guidance and educational purposes only. They do not constitute financial or tax advice. If you have complex tax circumstances or need certainty about your tax position, we recommend consulting a qualified accountant or tax adviser, or contacting HMRC directly.
