This uses your average price. Real rounds have lots of different prices, a few commercial jobs and some customers on longer gaps. To see the rise customer by customer, with your real prices, use the Price Rise sheet in the round book.

How it works

We work out how many times a year each customer is cleaned (52 divided by the weeks between cleans), multiply by the price, and compare the old and new totals. The customers you could lose is how many could leave before the higher prices from everyone else stop covering them.

New price: your average price plus the rise, rounded up to the next 10p, 50p or £1 if you pick one.
Takings a year: customers × price × cleans a year.
Customers you could lose: customers × (1 take away old price ÷ new price), rounded down.

Tips

Tell customers in writing a few weeks before the new price starts.
Rises often land better at the start of spring than in the middle of winter.
Keep a note of who you told and when. The round book has a Told on column for this.
