Freelancer Tax Health ScoreYour freelancer tax health score is a fast way to see whether your self-employment finances are genuinely under control, or quietly heading for a January scramble. Rather than guessing, the tool above scores how ready you are across the things HMRC actually cares about: being registered, keeping records, putting money aside, and hitting deadlines.

Gilt Ladder CalculatorSpread a lump sum across gilts maturing in successive years, so cash comes back to you steadily - and tax-efficiently, since gilt gains are free of Capital Gains Tax. Build your ladder and see the year-by-year maturity schedule.
Gilt Yield Calculator (After-Tax)Work out the real, after-tax return on a UK government gilt - and see the savings rate you'd need to beat it. Because gilt capital gains are free of Capital Gains Tax and only the coupon is taxed, a low-coupon gilt bought below £100 can comfortably out-earn a taxed savings account, especially for higher and additional-rate taxpayers.
Gilt vs Savings vs ISA CalculatorWhere should your cash live? Compare the after-tax return on the same lump sum across a taxed savings account, a low-coupon gilt (gain CGT-free), a cash ISA and Premium Bonds - and see the clear winner for your tax band.
Holiday Entitlement CalculatorThis holiday entitlement calculator works out the statutory paid annual leave you are legally owed, based on how many days or hours you work each week. Almost every UK worker builds up at least 5.6 weeks of paid holiday a year, but the figure in days depends on your pattern of work, and part-timers, shift workers and people who start partway through the leave year are easy to short-change. Whether you are an employee checking a contract, a manager setting up rotas, or a new starter wondering how much leave you have, enter your working pattern above and read on to see exactly how the maths is done.
Hourly Rate CalculatorThis hourly rate calculator turns a salary into an hourly figure, and converts the other way too, so you can compare any job or contract on a like-for-like basis. Pop in your pay, choose how often you're paid and the hours you work, and you'll see your rate in seconds. It's built for anyone weighing up a new role, a freelance day rate, an overtime shift or a part-time offer. The figures here are gross (before tax) unless you say otherwise, which keeps the comparison clean before deductions come into play.
House Deposit CalculatorUse our free House Deposit Calculator to get an instant estimate.
IR35 Status CheckerThis IR35 calculator helps you check whether a contract is likely to fall inside or outside IR35 (the off-payroll working rules) by walking through the working practices HMRC actually looks at. It is built for UK limited-company contractors, freelancers and the clients who engage them, and gives you a plain-English read on your status before money or deadlines are on the line. IR35 decides whether HMRC treats you as genuinely in business on your own account, or as a "disguised employee" who should be taxed almost like an employee. Get it wrong and the bill, plus interest and penalties, can be severe.
Import Duty CalculatorUse our free Import Duty Calculator to get an instant estimate.
Income Tax CalculatorThis income tax calculator shows exactly how much Income Tax you pay on your salary in the 2026/27 tax year, and what is left as take-home pay once National Insurance is taken into account. Enter your gross salary above and you get the tax due, the effective rate as a percentage of your wages, and your net pay broken down by month and by year. It is a full UK tax calculator for employees on PAYE across England, Wales and Northern Ireland, with a note on where Scotland differs. You will see how the £12,570 personal allowance and the 20%, 40% and 45% bands apply to your income, plus how a pension or student loan changes the result.
Index-Linked Gilt CalculatorIndex-linked gilts ("linkers") protect your buying power: the principal grows with inflation on top of a real yield. Project the nominal value at maturity and see the inflation-proof real return.
Inheritance Tax CalculatorUse our free Inheritance Tax Calculator to get an instant estimate for the 2026/27 tax year.
LBTT Calculator (Scotland)Use this LBTT calculator to work out the Land and Buildings Transaction Tax due on a Scottish property purchase, including first-time buyer relief and the Additional Dwelling Supplement.

Whether you let a single flat or run a growing portfolio, it keeps every figure in one place so you can see your position at a glance. Your details are saved in your browser, so you can return and update them as the year progresses, ready for your Self Assessment return.
Late Payment Interest CalculatorThis late payment interest calculator works out the statutory interest you are legally entitled to charge on an overdue business invoice under the Late Payment of Commercial Debts Act. Enter the invoice amount and the dates to get the interest owed plus the fixed compensation you can add on top. Statutory interest runs at 8% above the Bank of England base rate, and you can also claim between £40 and £100 in compensation per invoice depending on its size.
