Round Profitability Calculator

Divide the price you charge by the total time the visit costs you — and the total has to include driving there and back, not just the time on site. A £30 job that takes 30 minutes on site looks like £60/hr. Add a 20-minute round trip and it's really £36/hr. The calculator above does this for every job — mowing, pressure washing, gutters, window cleaning, anything — ranks them best to worst, and flags the ones quietly costing you money in red.

Because driving is unpaid time that doesn't show on any invoice. Two jobs at the same price can earn wildly different hourly rates once travel is counted — the close one wins every time. Tightening your round geographically (clustering customers by area and day) is usually the single biggest lever on a solo operator's real hourly rate, ahead of putting prices up. It applies to every outdoor service, not just lawn care.

Most established solo operators — gardeners, mowing rounds, pressure washing, gutter and window cleaning — aim for £30–£50 per working hour after travel, before tax and expenses. New operators often start lower to win work. Rather than chase a fixed number, compare your jobs against your own round average — the calculator flags anything dragging well below it, which is where repricing pays off fastest.

Reprice first — most customers accept a modest rise, especially with a year's notice or at renewal, and keeping the slot filled beats an empty diary. Drop a customer only if they refuse a fair price AND they're far from the rest of your round. Moving an awkward job from weekly to fortnightly is a softer middle option: same income spread over fewer visits, less driving — and a weekly job drags your round average four times as hard as a one-off, so it's where the biggest wins are.

No. Everything runs in your browser — nothing is sent to a server or saved to an account. When you copy the shareable link, the customer names are deliberately stripped out, so you can send your numbers to a partner or accountant without sharing who your customers are.

BuildRound records each job's price and time as you work, so it can show you what you're earning per customer without rebuilding this spreadsheet by hand. It's £15/month with no per-customer fees. The calculator above is the quick one-off version; the app keeps the numbers up to date as your round changes.
