Most owners of an equipment hire business know roughly how busy they are. Far fewer know whether they are actually making money on each hire, where profit is leaking, or which part of the business is growing. Key performance indicators, or KPIs, answer those questions in a few numbers you can check every month.
This guide covers the 7 KPIs that matter most for an equipment hire business, how to calculate each one, and what to do when a number moves the wrong way.
Why KPIs matter more than turnover
Turnover tells you how much came in. It does not tell you whether prices cover costs, whether time is being used well, or whether cash will be there next month. A equipment hire business can grow turnover and still make less profit if costs grow faster. KPIs show you the drivers behind the result, early enough to act.
The 7 KPIs for an equipment hire business
1. Hires
How to calculate it: Hire contracts in the month
Your volume.
2. Average hire value
How to calculate it: Revenue ÷ hires
Rises with longer hires and add-ons.
3. Utilisation
How to calculate it: Days on hire ÷ days available per item
The single biggest driver of profit.
4. Maintenance % of revenue
How to calculate it: Repairs and inspections ÷ revenue
Rises as the fleet ages.
5. Revenue per item
How to calculate it: Revenue ÷ items in the fleet
Which kit earns its keep.
6. Damage recovery
How to calculate it: Damage charges recovered ÷ damage costs
Protects margin.
7. Overdue returns
How to calculate it: Items past their return date
Lost hire days and risk.
Interpreting these measures in practice
Measure utilisation by asset, using rentable days divided by days the item was available for hire. Pair utilisation with downtime, repair cost, delivery cost and contribution after finance; a heavily used item can still be a poor asset if it needs frequent repairs or low-priced hires. Track reservation cancellations and late returns because they affect availability for the next customer. Use these records to decide whether to reprice, repair, replace or buy another unit. Also distinguish seasonal demand from avoidable idle time: compare like months year on year, then review whether inspections, delivery capacity or repair delays kept otherwise rentable equipment off hire.
Start with the profit basics
Alongside the industry KPIs above, every owner should check four headline figures each month:
- Total income for the month and year to date
- Total costs, split into direct costs and overheads
- Net profit and operating margin
- Lowest cash balance in the next 12 weeks, from a cash flow forecast
If net profit is falling while turnover rises, look at the cost KPIs first. If cash is tight while profit looks fine, look at unpaid invoices.
An example month (illustrative figures)
Say an equipment hire business takes £16,000 in a month and spends £7,500 on the direct costs of delivering the work. Gross profit is £8,500, a gross margin of 53%. If last month the margin was several points higher on similar turnover, something has changed in prices, costs or the mix of work, and the KPIs above show where to look. These figures are illustrations only: use your own.
What to do when the numbers slip
- Raising utilisation before buying more kit
- Charging for delivery, cleaning and damage waivers
- Selling consumables with every hire
- Retiring kit that rarely goes out
Pick one action at a time, so you can see what made the difference. If you are asking what the business could pay you, read how much an equipment hire owner earns in the UK.
How to review your KPIs every month
1. Update your records for the month: hires, sales, costs and invoices. 2. Compare each KPI with last month and the same month last year, so seasonal swings do not mislead you. 3. Pick the one number that moved most in the wrong direction and find out why. 4. Decide one action for next month, such as a price change, a rota change or chasing a debtor. 5. Check the result at the next review.
Fifteen minutes a month on this routine is enough to catch most problems while they are still small.
Common mistakes with KPIs
Tracking too many numbers. Pick the handful that drive your profit and review them consistently.
Looking at one month in isolation. Trends matter more than single results.
Not acting on what you find. A KPI that never changes a decision is just a number.
Keeping figures in your head. Write them down, or let a spreadsheet calculate them, so nothing is guessed.

Frequently asked questions
What is the most important KPI for an equipment hire business? Gross margin, because it shows whether your prices cover the direct cost of each hire. If it is wrong, growth only makes things worse.
Which KPIs should a new equipment hire business track first? Start with hires, average hire value and utilisation. They are quick to work out and show straight away whether your pricing and capacity are right.
Can KPIs help me set prices? Yes. If your margin or rate per hire is below target, your prices are too low for your costs, however busy you are.
What is a good gross margin for an equipment hire business? There is no single benchmark, because margins depend on your mix of work, location and whether you pay staff. The useful test is your own trend: a margin that holds steady or rises as you grow is healthy, and a falling one needs action on price or costs.
How often should I check my KPIs? Monthly for most figures, and weekly for cash and unpaid invoices.
Do I need software to track KPIs? No. A spreadsheet that calculates the figures from your records works well for most small businesses and avoids monthly fees.
