This is an illustrative example, not a prediction or a guarantee. To judge the actual result you also have to deduct your advertising costs and the Modern PPC management fee. Actual contribution depends on your equipment costs, labor, pricing, and other expenses.

Your Lead & Job Goals
How many opportunities you want, and how many turn into work.
Your Job Economics
What a job bills for, and what it costs you to deliver.
Allocated overhead is the share of trucks, insurance, rent, administration and similar operating costs assigned to each completed job. Enter the portion you want attributed here — if it’s already inside your materials and labor figure, set this to $0 so the same cost isn’t counted twice.

- Modern PPC management fee$2,000/month, plus a one-time $1,500 setup fee. Includes management of up to $10,000/month in combined ad spend.

What Happens If You Complete More or Fewer Jobs?
Same job economics and marketing investment, at different volumes.
How the Calculator Works.
Every figure in the tool is derived from the inputs above. Here is what each one means and which costs it does and does not include.
- Contribution per job
- Job price less materials, labor, and allocated overhead. It is what a job leaves behind to cover marketing — not profit, because marketing has not been deducted yet.
- Contribution before marketing
- Contribution per job multiplied by the number of additional completed jobs.
- Estimated contribution after marketing
- Contribution before marketing, less your advertising budget and the Modern PPC management fee. Taxes and anything not entered above sit outside this model.
- Break-even completed jobs
- The minimum number of additional jobs needed to cover the whole marketing investment. Rounded UP, because one job fewer does not cover it.
- Break-even cost per lead
- What a lead can cost before advertising and the management fee together stop paying. It includes the fee amortised across leads.
- Allocated overhead
- The share of trucks, insurance, rent, and administration assigned to each job. If that cost is already inside your materials and labor figure, set it to $0 so it is not counted twice.
The calculator is a planning model, not a forecast. It shows what the arithmetic does with your assumptions — it does not predict advertising performance, and it does not promise completed jobs.
