About Contractor Pay UK: Day Rate

Contractor Pay UK turns a day rate into the money you actually keep: it compares estimated net pay across a limited company, an umbrella company and sole trader self-employment for 2026/27 and 2025/26.

Type what you bill and the days you work. The Company tab runs the numbers for a limited company: running costs, a director's salary, corporation tax, dividends and the tax on both. It tries every whole-pound salary the company can afford and picks the one that leaves you the most, then draws a step-by-step chart of where each pound goes.

The Compare tab runs the same day rate through an umbrella company calculator, with editable weekly margin and employer costs, showing the estimated annual and monthly difference.

The Sole trader tab shows profit, income tax and Class 4 contributions, how much to set aside each month, and the dates and amounts of your payments, including advance payments.

The Dates tab lists the deadlines that matter for the next fourteen months: your own return, corporation tax, accounts, VAT quarters and payroll. Turn on a bell and your phone reminds you at 9am, a few days before. Reminders work offline.

Save any result, compare two or three side by side, and share a one-page PDF or an image.

Rates are for 2026/27, with 2025/26 selectable, and every figure comes from the official gov.uk pages (checked 8 November 2026). Everything is worked out on your phone; there is no account and your numbers never leave it.

What’s new

Version 1.0.1 · Updated November 10, 2026

Fixed how numbers are read: a day rate typed as "525,50" was read as £52,550, and text that was not a number was silently counted as 0. Amounts now follow your phone's decimal separator, and anything unreadable shows a message under the field. Countdowns no longer lose a day around the clock change, and the PDF report writes its date as "5 Nov 2026" so it cannot be misread.
