Each tool runs entirely in your browser. Nothing is saved on our servers.
The ones people come back to — pricing a job, getting the VAT right, and putting a document in front of a customer.
Work out what to charge before you quote, and what you actually made after.
Work back from your overheads, the profit you need and the hours you can actually bill to the rate that covers it.
Open tool →The same maths in days, with a half-day rate and the effect of losing billable days to weather and quoting.
Open tool →Price a job before you quote it: labour, materials, subbies, plant, overhead recovery and the margin you need.
Open tool →Price and cost in, margin and markup out — plus the price you would need for a margin you are aiming at.
Open tool →The one people get wrong. Convert between the two and see the selling price each one produces.
Open tool →Work out what a finished job actually made — revenue against real costs, the margin, the profit per labour hour, and which category overran the plan.
Open tool →What an employee's hour costs you, and what it has to be sold for.
VAT, CIS, structure and getting paid late. Arithmetic you can check, with the source linked.
Add VAT to a net figure or take it back out of a gross one, with net, VAT and gross split out.
Open tool →What a contractor withholds after materials, plant hire and the other permitted exclusions come out.
Open tool →The same profit through both structures, with every tax line shown and what the comparison leaves out.
Open tool →Statutory interest on an overdue commercial invoice, split correctly across the half-years it ran through.
Open tool →Put something in front of a customer that looks like it came from a real business.
A UK invoice with the details HMRC expects, your logo on it, and a clean print to PDF.
Open tool →A quote with line items, scope, exclusions and an acceptance block — the difference between winning and re-pricing.
Open tool →Codes for a website, a payment link or a review page, as PNG or SVG, generated in your browser.
Open tool →Mileage, van costs and what to recover for getting to site.
Area, tiles and slates — measure once, order right, quote from the same numbers.
Plan dimensions and a pitch in, true sloped area out — the number every material order starts from.
Open tool →Tile counts from a roof area and a coverage figure, with waste added so you order in full packs.
Open tool →Batten gauge, slates per square metre and the delivery weight, from the size and headlap you are laying.
Open tool →The odd jobs: labels, codes and everything that did not fit anywhere else.
Most of these calculations exist in some form online already — but every version we tried either gated the result behind an email signup, was buried in advertising, or had the maths subtly wrong (especially the VAT and margin/markup ones). So we built our own.
If you're at the point where these tools are useful, you're probably also at the point where operational software starts paying for itself — but you don't have to make that decision today. Use the free tools as long as they're useful; when they stop being enough, Cushty is here.
Book a 30-minute walkthrough — we'll show you how Cushty fits your business. No commitment, no contract until you choose to subscribe.
