What is the 5% Factor Tool and how does it work?
The 5% Factor Tool is a simple spreadsheet where you enter your current numbers and then model what small percentage improvements do to your yearly profit. You put in your hourly rate, your billable efficiency as a percentage, your average monthly materials spend, your cost of sales, and your operational expenses. The tool then shows you the dollar impact of each change in isolation and in combination.
Your accounting software is the starting point for getting those numbers right. In Xero, run a profit and loss for a 12-month period and use the percentage of sales analysis to find your cost of sales and net profit percentages. The same report exists in MYOB and QuickBooks. Once you have those figures, they go straight into the tool.
How do you work out your billable efficiency?
Billable efficiency is the share of your working hours you can actually charge a client for. A rate of 75% might look like six billable hours inside an eight-hour day for service and maintenance work. An 80% rate might look like four full days of charged work in a five-day week.
If you are the owner working on your own with 40 available hours per week, a 75% efficiency rate gives you 30 billable hours per week. That number, combined with your hourly rate, is the foundation the tool builds on.
What does a 5% price increase actually add over a year?
Taking the example in the tool, a sole trader starting from a yearly profit of $16,000 who raises their rate by 5% with no other changes sees a small but real increase in profit for that year. A separate 5% efficiency gain, with the rate left unchanged, adds around $1,000. Combining both a 5% rate rise and a 5% efficiency improvement pushes the gain to around $2,000 over the year.
These are incremental numbers, but they come from one person making two changes and doing nothing else differently.
How much can a 5% materials discount add?
If your monthly materials spend is $5,000 and you negotiate a 5% reduction with your main suppliers, the tool shows an additional $3,000 of profit at the end of the year with no other changes made. The starting point is to look at what you have spent with your largest suppliers over the past year and ask whether there is room for movement on price.
When all three changes are combined, a 5% price increase, a 5% efficiency gain, and a 5% materials discount, the example in the tool shows around $5,000 of additional yearly profit for a sole trader working alone, with no new staff added.
What happens to those numbers if you hire another tradesperson?
Adding another tradesperson to the business and then applying those same three 5% changes produces significantly higher profit figures than the sole trader scenario. The tool lets you model that comparison directly so you can see what hiring actually does to the bottom line when it is combined with pricing, efficiency, and materials discipline.
The broader point is that multiple small gains in different parts of the business compound. Taking 5% at a time and identifying where that improvement is realistically possible right now is a practical way to inch the business forward without making one large, risky change.
How do you read a zero-profit result in the tool?
If your current position is a loss or zero net profit, the tool still works. It shows you how much the 5% changes reduce that loss, which is an improvement even if it does not immediately produce a positive number. The goal is a better position than where you currently are, not perfection from the first run.
