Profit & Loss StatementThis profit and loss calculator turns your sales, costs and overheads into a clear P&L statement in seconds, showing gross profit, net profit and the margins behind them. It is built for UK sole traders, freelancers and small limited companies who want to know whether the business is actually making money before the accountant confirms it. Enter your figures above, and you get a tidy summary you can sanity-check against your bookkeeping, your bank balance and your tax return. No jargon, no spreadsheet formulas to remember.
Profit Margin CalculatorUse our free Profit Margin Calculator to get an instant estimate.
R&D Tax Credit CalculatorThis R&D tax credit calculator helps UK limited companies estimate the qualifying spend behind a Research & Development claim and the rough cash benefit it could unlock against their corporation tax bill. If you have staff, subcontractors or cloud costs tied to solving a genuine technical problem, you may have a claim and not realise it. It is built for company directors, finance leads and accountants who want a quick, honest sense of scale before committing to the full HMRC paperwork for the 2026/27 accounting period.
Receipt Scanner (OCR)This free receipt scanner app reads a photo or PDF of any UK receipt and pulls out the four things that matter for your books: the supplier, the date, the total and the VAT. Drop in a crumpled lunch receipt, a fuel station printout or a supplier invoice, and the optical character recognition (OCR) does the typing for you. It is built for sole traders, freelancers and small limited companies who need to scan receipts for tax without paying for bookkeeping software. Nothing here is a rate that changes each April, so it works the same in every tax year.
Redundancy Pay CalculatorOur redundancy pay calculator estimates the statutory redundancy you're owed from three things: your age, your length of continuous service and your weekly pay. If you've just been told your role is at risk, you want a clear figure you can sanity-check against your employer's offer, not a vague promise. This statutory redundancy calculator uses the standard age-banded formula the government applies, so you can see what the law guarantees as a minimum before any enhanced or contractual top-up your employer may add on top.
Rent Affordability CalculatorUse our free Rent Affordability Calculator to get an instant estimate.
Rent Receipt GeneratorOur free rent receipt generator creates a professional rent receipt PDF for tenants and landlords in seconds, with no signup required. Simply record the amount, property, rental period and payment method, and download a ready-to-use document. A clear rent receipt gives both parties reliable proof that rent has been paid, which is useful for record keeping, deposit disputes and tax purposes. Generate unlimited receipts whenever you need them, completely free.
Rental Yield CalculatorThis rental yield calculator works out the gross and net return on a UK buy-to-let property, so you can see what your rent actually earns against the price you pay. Enter the purchase price (or current value) and the rent, add your running costs, and you get both figures in seconds. It is built for landlords, first-time investors and anyone comparing two properties before making an offer. Yield is the single number that lets you weigh a cheap flat in one town against a pricier house in another on a like-for-like basis.
Required Salary CalculatorMost calculators go one way: gross salary in, take-home out. This required salary calculator works in reverse. Tell it the amount you want to actually take home - per month or per year - and it finds the gross salary you need to earn to land on it, after Income Tax, National Insurance and any pension or student loan deductions. It is built for employees paid through PAYE in England, Wales and Northern Ireland, with Scotland selectable, and uses the same verified 2026/27 tax figures as our forward salary calculator, so the two always agree.
Salary Calculator (Take-Home Pay)This salary calculator turns the headline figure on your contract into the number that actually lands in your bank account each month for the 2026/27 tax year. Enter your gross annual salary above and you will see your take-home pay after Income Tax and National Insurance, broken down so you can see exactly where the deductions go. It is built for employees paid through PAYE in England, Wales and Northern Ireland, with a note on how Scotland differs. If you have a pension, a student loan or a company car, read on for how those change the result.
Salary Sacrifice 2029 NI CalculatorFrom April 2029 , pension salary sacrifice above £2,000 a year will be subject to both employee and employer National Insurance. See how much the change will cost on your sacrifice.
Salary Sacrifice CalculatorThis salary sacrifice calculator shows how giving up part of your gross pay for an employer pension contribution cuts your Income Tax and National Insurance, and what each pound in your pension actually costs your take-home pay. It is built for UK employees deciding how much to sacrifice in the 2026/27 tax year. You will see the real trade-off: a smaller payslip now, but more going into your pension than the headline reduction, because the taxman and NI no longer touch that slice. Enter your salary and the amount you want to sacrifice to get your numbers.
Salary vs Dividend CalculatorUse the dividend vs salary calculator above to compare how much tax you pay taking income as salary versus dividends, and find the most efficient split for a company director in 2026/27.
Section 24 Landlord Tax CalculatorThis Section 24 calculator shows how the mortgage-interest restriction changes the tax on your rental income, so you can see your real buy-to-let tax bill rather than guessing. Since the rules fully bit in 2020/21, you can no longer deduct mortgage interest from your rental profit. Instead you get a flat 20% tax credit on finance costs, which hits higher and additional-rate landlords hardest. Enter your rent, mortgage interest and other costs above to estimate the damage for the 2026/27 tax year, then read on for the formula and worked examples.
Self Assessment Penalty CalculatorThis self assessment penalty calculator helps you estimate the HMRC charges that build up when a tax return or payment is late, so you can see roughly what you owe before the figure grows any larger. It works through the late filing penalties, the separate late payment penalties and the interest that runs alongside them. It is built for anyone in the Self Assessment system for the 2026/27 tax year and earlier years: sole traders, landlords, company directors, high earners and people with side income. Enter your tax owed and how late you are to get a guide figure in seconds.
Self-Employed Tax CalculatorThis self employed tax calculator estimates the Income Tax and Class 4 National Insurance you owe on your profits for the 2026/27 tax year (6 April 2026 to 5 April 2027). Enter your profit (turnover minus allowable expenses) and it shows your tax bill, your NI, and what you actually keep. It is built for sole traders, freelancers and side-hustlers who file a Self Assessment return and want a quick, honest figure before the 31 January deadline lands. The maths below is laid out in full so you can see exactly how the result is reached.
Side Hustle Tax CalculatorUse the side hustle tax calculator above to work out the tax on income from a side project alongside your main job, and whether the £1,000 trading allowance covers you.
Stamp Duty CalculatorThis stamp duty calculator shows what you'll pay in property tax when you buy a home in the 2026/27 tax year, whether that's Stamp Duty Land Tax (SDLT) in England and Northern Ireland, Land and Buildings Transaction Tax (LBTT) in Scotland, or Land Transaction Tax (LTT) in Wales. Enter the purchase price, pick the nation, and flag whether you're a first-time buyer or buying an additional property. Buying a home is stressful enough without a surprise tax bill at completion, so it helps to know the figure before you offer.
State Pension Forecast CalculatorOur state pension forecast calculator helps you estimate your new State Pension from your National Insurance qualifying years, and see how many more years you need for the full amount. Knowing your forecast early makes it easier to plan your retirement income and decide whether topping up your NI record is worthwhile. Simply enter your qualifying years to see an estimated weekly, monthly and yearly figure, so you can understand where you stand long before you reach State Pension age.
Statutory Sick Pay CalculatorThis statutory sick pay calculator helps you work out whether you qualify for SSP and roughly how much you should be paid while you are off work ill in the 2026/27 tax year. Statutory Sick Pay is the legal minimum your employer must pay if you meet the rules, and it is the same across England, Scotland, Wales and Northern Ireland. It is built for employees who are signed off sick, on a phased return, or unsure whether the first few days count. Enter your details above to see your likely entitlement, then read on for the formula, worked examples and the mistakes that catch people out.
Student Loan Repayment CalculatorThis student loan repayment calculator shows how much comes out of your pay each month and year once your income passes your plan's repayment threshold. It covers the main income-contingent plans, including Plan 2, plus the Postgraduate Loan, using the 2026/27 rules. Pick your plan, enter your salary, and see the deduction PAYE will take. It is built for anyone budgeting around a payslip, weighing up a pay rise, or simply checking a deduction that looks higher than expected.
Tax Code CheckerAround 1 in 3 UK tax codes are wrong - and a wrong code means you're quietly overpaying (or building up a bill). Enter your tax code and find out in seconds whether it looks right, what it means, and what to do.
Tax Deadline TrackerThis tax deadline tracker shows every UK tax date you actually need to worry about in 2026/27, with a live countdown so nothing creeps up on you. Pick the deadlines that apply to you - Self Assessment, payments on account, VAT, PAYE or capital gains reporting - and see how many days you have left, then add them straight to your calendar. It is built for sole traders, landlords, company directors and anyone who files a tax return and would rather not pay a penalty for forgetting a date. All figures are checked for the 2026/27 tax year (6 April 2026 to 5 April 2027).
