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.
Take-Home Income CalculatorThis take-home income calculator goes beyond a single payslip, helping you see your true net income across employment, self-employment and other earnings combined. Work out your take-home income after tax and National Insurance - your true net income from a salary - using official UK 2026/27 rates. Because it looks at your total income rather than just one job, it gives a clearer picture of what you actually keep once all deductions are applied, making it ideal if you have more than one source of money coming in.
Take-Home Pay CalculatorThis take-home pay calculator is our canonical tool for working out your real net pay, showing both the annual and monthly amount that lands in your bank account after Income Tax, National Insurance, pension contributions and any student loan are taken from your gross salary. It's built for the 2026/27 UK tax year (6 April 2026 to 5 April 2027) and works for employees in England, Wales, Northern Ireland and Scotland. Whatever your salary, the gap between the headline figure and your real net pay can be a shock. Enter your details above and you'll see the deductions broken down line by line, so you know where every pound goes.
Take-Home Paycheck CalculatorThis take-home paycheck calculator shows what you actually keep from each individual pay run, breaking down a single payslip rather than just your annual figure. Calculate your take-home paycheck after income tax and National Insurance, and see exactly what hits your account each pay packet, weekly or monthly. Whether you are paid every week or once a month, it works out your net pay per payslip so you can budget around the money that genuinely reaches your bank, not the headline salary on your contract.
Take-Home Wage CalculatorThis take home wage calculator is built for people paid weekly or four-weekly, showing exactly what lands in your account after deductions. Calculate your take-home wage after tax and National Insurance - ideal for hourly, weekly and shift workers - using official UK 2026/27 rates. Whether your hours change from one week to the next or you pick up extra shifts, you can quickly see your pay broken down per week, month and year so there are no surprises on payday.
Tax CalculatorThis UK tax calculator shows exactly how much Income Tax and National Insurance you pay on any salary in the 2026/27 tax year, and what is left as take-home pay. Enter a figure above and you get the tax, the NI, the effective rate as a percentage of your wages, and your net pay broken down by year and by month. It works for employees on PAYE and gives a clear estimate for the self-employed, covering England, Wales and Northern Ireland, with a note on where Scotland differs. Below the result you will find the tax bands, the maths behind each deduction, and worked examples so you can check the numbers yourself.
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).
Tax Rebate CheckerMost UK taxpayers overpay. Answer a few quick questions and check what tax you could be owed - the rebates, reliefs and allowances you're missing, how much each is worth to you, and exactly how to claim it back.
Tax Refund EstimatorThis tax refund estimator helps you work out whether you have overpaid tax and roughly how much HMRC might owe you back for the 2026/27 tax year, plus the four years before it. It is built for employees on PAYE, people who changed jobs, anyone put on emergency tax, and those with job expenses they never claimed. Enter your income and the tax already deducted, and the tool compares it against the correct figure using current rates. You get a guide figure in seconds, so you know whether a claim is worth your time.
Tax-Free Childcare CalculatorOur tax-free childcare calculator shows exactly how much the government will add to your childcare costs in just a few seconds. For every £8 you pay into your childcare account, the government adds £2 - that is a 25% boost on top of what you contribute, up to £2,000 per child a year (£4,000 if your child is disabled). Enter your expected childcare spending below to see your potential top-up instantly, helping you plan nursery, childminder and after-school fees with confidence.
Tip CalculatorThis tip calculator works out a fair gratuity on any bill and splits the total between as many people as you like, so nobody is left doing sums on a napkin. Enter the bill amount, choose a percentage, and you get the tip, the grand total, and the amount each person owes in seconds. It is built for UK diners, group meals, taxi fares and takeaways, handling odd numbers and rounding cleanly. Whether you tip 10%, 12.5% or round up to the nearest pound, you will see exactly what lands on the card machine.
Umbrella Company CalculatorUse our free Umbrella Company Calculator to get an instant estimate for the 2026/27 tax year.
VAT CalculatorThis VAT calculator adds or removes UK VAT from any price in seconds, at the standard 20% rate or the reduced 5% rate. Type in a figure, choose whether it already includes VAT, and you get the net price, the VAT amount and the gross price side by side. It is built for sole traders, freelancers, small business owners and anyone checking a quote, an invoice or a receipt. No sign-up, no spreadsheet, and the same maths HMRC expects you to use. Below the tool you will find the formulas spelled out, worked examples with real numbers, and the mistakes that catch people out most often.
VAT Invoice CheckerThis VAT invoice checker tells you whether the document in front of you is a valid full VAT invoice you can actually reclaim VAT on. If a single required detail is missing, HMRC can refuse your input tax claim and you will have paid the VAT without getting it back. The tool runs through HMRC's checklist for you so you do not have to memorise it. It is for VAT-registered sole traders, limited companies and bookkeepers in the UK who want to clear the doubt before adding an invoice to a VAT return. Paste or enter the invoice details, and it flags what is present, what is missing and whether the document counts as full, simplified or neither.
VAT Number ValidatorOur UK VAT number checker lets you confirm whether a VAT number is correctly formatted and passes the HMRC checksum before you trust it on an invoice. Enter a GB number and we instantly validate its length and run the official mod-97 calculation, so you can catch typos and obvious mistakes in seconds. This is a format and checksum test, not a live registration lookup, so it helps you spot numbers that cannot be genuine before you reclaim input VAT or raise paperwork. Use it as a quick first line of defence whenever you receive a supplier invoice.
Wage CalculatorThis wage calculator is built for workers paid by the hour, week or month rather than on a fixed annual salary, turning whatever rate you earn into a clear take-home figure after Income Tax and National Insurance for the 2026/27 tax year. It's ideal for anyone who wants to know what actually lands in their bank account, from someone on a set hourly rate to an employee checking their payslip. Enter your wage and hours above, pick how you're paid, and the tool does the rest. Below, you'll see exactly how the figures are worked out so you can trust the result.
Weekly Pay CalculatorThis weekly pay calculator turns whatever pay figure you have - an hourly rate, a monthly salary or an annual package - into a clear weekly amount, and works backwards too. It is built for the 2026/27 tax year (6 April 2026 to 5 April 2027), so the National Insurance and Income Tax thresholds it references are current. Use it to sanity-check a payslip, compare a new job offer paid monthly against one quoted by the hour, or work out the weekly budget you actually have to live on. It is free, needs no sign-up, and shows the maths rather than hiding it.
Debt-to-Income Ratio CalculatorYour debt-to-income ratio (DTI) compares your monthly debt payments to your monthly income - a quick measure of how affordable your borrowing is, and something mortgage lenders pay close attention to. Enter your figures to see your ratio and how lenders are likely to view it.
Lifetime ISA CalculatorA Lifetime ISA (LISA) gives you a 25% government bonus on up to £4,000 a year - up to £1,000 of free money - to put towards your first home or retirement. This calculator projects your pot, including the bonus and any investment growth, year by year.
Director's Loan CalculatorIf you take money out of your company beyond your salary, dividends or expenses, it goes on your director's loan account . This calculator works out the S455 tax on an overdrawn loan and the benefit-in-kind cost when the loan is over £10,000.
Couples Tax OptimiserThe UK taxes individuals, not households. The same savings account can be tax-free in one partner's name and taxed at 40% in the other's. Enter your figures above and see what holding the money in the right name would save, every year.
Pay Rise Tax Trap CalculatorBetween £60,000 and £125,140 the UK tax system hides three cliff edges where a rise can be taxed at 60%, 70% or effectively more than 100% for a family using childcare. Enter your rise above: we show what you really keep and the exact pension contribution that dodges the cliff.
Buy-to-Let Profit CalculatorThis buy-to-let profit calculator shows what you actually keep after costs and tax - including the Section 24 rules that stop individual landlords deducting mortgage interest, and corporation tax if you hold the property in a limited company.
