Payments on Account CalculatorOur payments on account calculator helps you work out whether you owe Self Assessment payments on account, how much each one is and when they're due. Payments on account are advance contributions towards your next Self Assessment tax bill, spreading the cost so you don't face one large lump sum. Enter your figures to check whether HMRC expects these advance payments from you, plan ahead for each instalment and avoid surprise demands or interest charges when your return is filed.
Payroll CalculatorUse our free Payroll Calculator to get an instant estimate for the 2026/27 tax year.
Payroll Take-Home CalculatorOur payroll take-home calculator shows you the same figures you would expect to see on your payslip, so you can quickly sense-check what your employer's payroll has worked out. Enter your salary and it breaks down every deduction line by line. Work out your take-home pay after every payroll deduction - income tax, National Insurance, pension and student loan - for the 2026/27 tax year. It is a handy way to confirm your net pay before payday and spot any discrepancies in your wages.
Payslip GeneratorOur free payslip generator lets you create an unlimited UK payslip PDF with no signup. Enter salary, tax code, pension and student loan to see a full payslip with income tax and National Insurance. Each payslip itemises your gross pay, deductions and net take-home pay so you can keep clear records, check your figures or share a professional document in seconds.
Pension Annual Allowance CalculatorUse our free Pension Annual Allowance Calculator to get an instant estimate for the 2026/27 tax year.
Pension CalculatorThis pension calculator projects how big your pension pot could grow by the time you retire, based on what you pay in now, what your employer adds, the tax relief on top, and the investment growth you assume along the way. It is built for UK savers paying into a workplace scheme or a personal pension who want a realistic picture rather than a vague hope. Punch in your current pot, monthly contributions and target retirement age, and you will see a projected figure plus the gap between where you are heading and where you want to be.
Pension Drawdown CalculatorUse our free Pension Drawdown Calculator to get an instant estimate for the 2026/27 tax year.
Pension Inheritance Tax Calculator (2027)From 6 April 2027 , most unused pension funds are counted as part of your estate for Inheritance Tax. See how much extra IHT your beneficiaries could face once your pension is included - and what it was before.
Pension Lump Sum Tax CalculatorUse our free Pension Lump Sum Tax Calculator to get an instant estimate for the 2026/27 tax year.
Pension Pot CalculatorThis pension pot calculator shows roughly how large your retirement savings could become if you keep paying in and let the money grow. You enter your current pot, what you and your employer add each month, the years left until you stop work and an assumed growth rate, and it projects a future value. It is built for anyone with a workplace pension, a personal pension or a SIPP who wants a clear picture rather than a vague hope. The figures are estimates: real returns, charges and inflation all vary, so treat the result as a planning guide, not a promise.
Pension Tax Relief CalculatorUse our free Pension Tax Relief Calculator to get an instant estimate for the 2026/27 tax year.
Percentage CalculatorThis percentage calculator does the three jobs you actually need: find a percentage of a number, work out what percentage one number is of another, and measure the percentage change between two figures. Type your numbers in and read the answer straight away. It is built for everyday UK money decisions, from checking a discount in the sales to seeing whether a 4% pay rise keeps up with rising bills. No formulas to remember, no rounding errors, and you can see exactly how each result is reached below.
Personal Loan CalculatorThis personal loan calculator turns three numbers - the amount you want to borrow, the interest rate and the repayment term - into the figure that actually matters: what leaves your bank account every month. It also shows the total interest you'll pay over the life of the loan, so you can see the real price of borrowing before you sign anything. It's built for anyone weighing up an unsecured personal loan in the UK, whether you're funding a car, a home improvement, a wedding or consolidating other debts. No personal details, no credit check, just the maths.
Personal Savings Allowance CalculatorOur personal savings allowance calculator shows how much of your savings interest is tax-free and estimates any tax due on the rest. It works out your Personal Savings Allowance (£1,000/£500/£0) alongside the £5,000 starting rate for savings, so you can see exactly where you stand for the year. Your allowance depends on which income tax band you fall into, and lower earners may pay no tax on savings at all. Enter your income and interest below to check your position in seconds.
Premium Bonds CalculatorUse our free Premium Bonds Calculator to get an instant estimate.
Pro Rata Salary CalculatorThis pro rata salary calculator turns a full-time advertised wage into the figure you will actually be paid for working fewer hours or days. Job adverts almost always quote the full-time equivalent, even for part-time roles, so the headline number can be misleading until you scale it to your real schedule. Enter the full-time salary and your working pattern and you get the pro rata amount in seconds. It is built for part-time staff, job-sharers, term-time workers and anyone dropping a day a week, with 2026/27 tax figures so you can also gauge the take-home.
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.
Regular Savings CalculatorThis regular savings calculator works out what a monthly regular saver account could grow to over the term, including the interest earned on every single deposit you make. Unlike a lump-sum tool, it accounts for the fact that money paid in during month one earns interest for far longer than money paid in during month eleven. Put in your monthly amount, the headline rate and how many months you'll save for, and you'll see the closing balance, the total you paid in, and the interest on top.
Remortgage CalculatorThis remortgage calculator shows, in pounds, what switching your mortgage to a new rate could do to your monthly payment and the total interest you pay over the term. You feed in your current balance, rate and remaining years, then the rate you have been offered, and it compares the two side by side. It is built for UK homeowners coming to the end of a fixed deal or sitting on their lender's standard variable rate, wondering whether moving is actually worth the hassle. Seeing both figures together makes it easy to judge whether the saving justifies the cost and effort of switching.
