Bank Statement Converter (PDF to Excel)A bank statement converter turns a PDF bank statement into a clean spreadsheet of transactions - date, description, money in, money out and balance - that you can sort, total and import into your bookkeeping. Instead of retyping months of entries by hand, you upload the PDF and get a CSV or Excel file back in seconds. It is built for UK sole traders, landlords, contractors and small limited companies who need their bank data in a usable format for Self Assessment, VAT returns or Making Tax Digital - free, with no account to set up.
Bonus Tax CalculatorUse the bonus tax calculator above to see how much of your bonus you actually keep after income tax and National Insurance, and how it stacks on top of your salary.
Break Even CalculatorThis break even calculator tells you exactly how many units you need to sell, or how much revenue you need to take, before your business stops losing money and starts making a profit. Enter your fixed costs, your selling price and the variable cost of making each sale, and you get your break-even point in seconds. It is built for UK sole traders, freelancers and small limited companies pricing a product or service, planning a launch, or sense-checking whether a new line will ever pay its way.
Business & Agricultural Property Relief CalculatorFrom April 2026 , Business Property Relief and Agricultural Property Relief are capped: 100% relief on a combined £1 million of qualifying assets, then only 50% relief above - an effective 20% Inheritance Tax rate. Estimate the new bill.

Capital Allowances CalculatorUse our free Capital Allowances Calculator to get an instant estimate for the 2026/27 tax year.
Capital Gains Tax CalculatorThis capital gains tax calculator works out what you owe HMRC when you sell or give away an asset that has risen in value during the 2026/27 tax year. Enter your gain, your other income and any costs, and it applies the £3,000 annual exempt amount and the 18% and 24% rates to estimate your bill in seconds. It is built for anyone selling shares, a second property, a buy-to-let, units in a fund, crypto or other chargeable assets, and it shows you the maths so you can see exactly how the figure is reached.
Car Tax CalculatorUse our free Car Tax Calculator to get an instant estimate for the 2026/27 tax year.
Cash Flow ForecastThis cash flow forecast calculator projects your business bank balance month by month, so you can see exactly when money gets tight before it actually does. You enter your opening balance, the cash you expect in, and the cash you expect out, and it rolls the closing balance forward across the year. It is built for UK sole traders, freelancers and small limited companies who want a simple 12 month cash flow forecast without wrestling with a spreadsheet. Profit on paper means little if the bank runs dry in month four. This tool shows you the months to plan for.
Child Benefit Tax CalculatorUse our free Child Benefit Tax Calculator to get an instant estimate for the 2026/27 tax year.
Company Car Tax CalculatorThis company car tax calculator works out the Benefit-in-Kind (BIK) you pay on a car your employer provides, for the 2026/27 tax year. Tell it the car's P11D value and its appropriate percentage and you'll see the taxable benefit, the income tax due, and roughly what it costs you each month. It's built for employees offered a company car or weighing one up against a cash allowance, and for company directors deciding what to put through the business. The numbers below explain exactly how the figure is reached, so you're not taking the result on trust.
Compare Tax Years CalculatorThe same salary does not always leave you with the same take-home pay. As the government changes Income Tax bands and National Insurance rates - or freezes thresholds while wages rise - the amount that reaches your bank account shifts from one tax year to the next. This compare tax years calculator puts two tax years side by side for an identical salary so you can see the difference in pounds. It uses the same verified figures as our salary calculator for each year, so the numbers line up exactly with the rest of the site.
Compound Interest CalculatorThis compound interest calculator shows how your money can grow when the interest you earn starts earning interest of its own. Enter a starting balance, a regular monthly deposit, an annual interest rate and the number of years, and you will see the projected balance and how much of it is growth rather than your own contributions. It is built for anyone planning ahead in the UK: savers building an emergency fund, parents saving for a child, or investors testing how a long-term pot might develop. It is a forecasting tool, not a tax calculator, so the figures depend entirely on the rate and deposits you choose.
Corporation Tax CalculatorThis corporation tax calculator estimates what your UK limited company owes HMRC on its taxable profits for the 2026/27 financial year, including the effect of marginal relief if your profits sit between the lower and upper limits. Enter your profit and the tool does the rest. It is built for company directors, contractors running a personal service company and small business owners who want a quick, honest figure before the accountant's bill lands. It applies the current rates and limits published by HMRC so you can plan cash flow with confidence.
Cost of Moving House CalculatorWork out the total cost of moving house in the UK in one place - stamp duty, conveyancing and solicitors' fees, survey, mortgage fees, estate agent and removals - so you know the real number before you commit.
Council Tax CalculatorUse our free Council Tax Calculator to get an instant estimate.
Dividend Tax CalculatorThis dividend tax calculator works out the tax due on your dividend income for the 2026/27 tax year, after the £500 dividend allowance and at the rates that apply to your income band. It is built for limited company directors, shareholders and anyone holding shares outside an ISA who needs a clear figure rather than a guess. Dividends sit on top of your other income, so the rate you pay depends on what you earn elsewhere. Enter your salary and dividends above and the tool stacks them correctly, then shows the tax band by band.
Dividend Voucher GeneratorThis free dividend voucher generator creates a clean, ready-to-keep dividend voucher PDF for your limited company in seconds. Enter the company, shareholder, shares held and dividend amount declared to produce a professional record you can store with your company books. A dividend voucher documents each dividend payment to shareholders and is an important part of your company's records. There is no signup and you can generate unlimited vouchers whenever you declare a dividend.

FIRE CalculatorUse our free FIRE Calculator to get an instant estimate.
Final Salary Pension CalculatorUse our free Final Salary Pension Calculator to get an instant estimate.
Fiscal Drag Calculator (Threshold Freeze)Income Tax thresholds are frozen until April 2031 . As your pay rises with inflation, more of it is dragged into tax - and into higher bands. See how much the freeze quietly costs you over the period.
Flat Rate VAT CalculatorThis flat rate VAT calculator works out what you would hand to HMRC under the VAT Flat Rate Scheme and lines it up against standard VAT accounting, so you can see at a glance which method leaves more in your business. It is built for sole traders, freelancers and small limited companies on (or thinking about joining) the scheme in the 2026/27 tax year. Enter your VAT-inclusive turnover and your sector's flat rate percentage, and you will get a clear figure plus the comparison that actually matters: the cash difference between the two ways of paying.
