How volume and price change it
Annual operating profit if you do more or fewer jobs, or charge more or less, than your figures.
| Price per clean | 10 jobs a month | 15 jobs a month | 20 jobs a month | 25 jobs a month | 30 jobs a month |
|---|---|---|---|---|---|
| £120 | £14,280 | £21,420 | £28,560 | £35,700 | £42,840 |
| £135 | £16,080 | £24,120 | £32,160 | £40,200 | £48,240 |
| £150 | £17,880 | £26,820 | £35,760 (your figures) | £44,700 | £53,640 |
| £165 | £19,680 | £29,520 | £39,360 | £49,200 | £59,040 |
| £180 | £21,480 | £32,220 | £42,960 | £53,700 | £64,440 |
What the calculation includes
- Your price per clean, excluding VAT
- The running cost per clean, for water, cleaning product, power, filter consumables and waste
- Your monthly finance payment, if you pay monthly
- The machine cost, excluding VAT, for payback when you buy outright
What it leaves out
- VAT, which most VAT-registered businesses reclaim on the machine and charge on cleans
- Income tax, corporation tax and capital allowances
- Technician wages and time
- Installation and training, if charged, and adaptors
- Premises, insurance, marketing and vehicle costs
- Filters that turn out to be damaged and can’t be cleaned
Monthly revenue is your price times your jobs a month. Monthly net is revenue less the running cost for each job and any monthly finance payment. Annual operating profit is twelve months of monthly net. Payback is the machine cost divided by monthly net, rounded up to whole months.
