Rental Income Tax CalculatorUse our free Rental Income Tax Calculator to get an instant estimate for the 2026/27 tax year.
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.
Retirement CalculatorThis retirement calculator estimates the pension pot you could build by your chosen retirement age from regular monthly saving, any lump sum you already hold and an assumed rate of investment growth. Tell it how much you pay in, how long you have and what return you expect, and it does the compounding maths for you. It is built for anyone in the UK weighing up a workplace pension, a SIPP or an ISA and asking the honest question: when can I afford to retire, and will what I am putting away actually be enough?

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 Comparison CalculatorUse our free Salary Comparison Calculator to get an instant estimate for the 2026/27 tax year.
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 to Hourly CalculatorThis salary to hourly calculator turns an annual salary into the hourly rate it actually works out to, based on the hours you really work each week. Enter your gross yearly pay and your contracted hours, and you get a clear pounds-per-hour figure you can compare against job ads, freelance day rates or a new shift pattern. It is built for UK employees, jobseekers and anyone weighing up a contract against a permanent role. The result is your gross rate before tax and National Insurance, so you can see exactly what an hour of your time is worth on paper.
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.
Savings CalculatorThis savings calculator shows how much your money could grow once interest starts working on it, whether you pay in a single lump sum, save a fixed amount each month, or both. Put in your starting balance, your monthly deposit, an interest rate and a time period, and you get a projected final balance plus a year-by-year breakdown. It is built for UK savers comparing accounts, setting a plan, or simply wanting to know what their pot might be worth in a few years' time.
Savings Goal CalculatorUse our free Savings Goal Calculator to get an instant estimate.
Scotland Tax CalculatorThis Scotland tax calculator works out your 2026/27 Scottish income tax, National Insurance and take-home pay using the Scottish bands set by the Scottish Government. If you live in Scotland, you pay income tax on your salary, pension or self-employment profits at different rates from the rest of the UK, and the result can be hundreds of pounds either side of an English payslip. Enter your annual salary above to see exactly where each pound goes - and how Scotland compares with England, Wales and Northern Ireland.
Second Home Stamp Duty CalculatorBuying a second home, investment property, or buy-to-let? You'll pay an additional property surcharge on top of the standard stamp duty rates. Our second home stamp duty calculator shows exactly how much you owe across England, Scotland, Wales and Northern Ireland for the 2026/27 tax year. The surcharge adds a flat 5% (or 8% in Scotland) to your bill the moment you own more than one residential property - here's how it works, when it applies, and whether you can avoid it.
Second Job Tax CalculatorThis second job tax calculator shows what a second income actually costs you in tax and National Insurance for the 2026/27 tax year, once both jobs are added together. Taking on extra work is a sensible move, but the wage slip from job two often looks smaller than you expected, and the reason is rarely the second job being "taxed more". It is about which job holds your tax-free allowance and how HMRC stacks your income. This page explains the maths, walks through real numbers, and flags the tax-code traps to watch.
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.
