Business and pricing
Margin, markup, commission, asset depreciation and what a campaign costs. The sums you do before setting a price.
Costs and campaigns
2 tools- Straight-line depreciation How much you can write off each year on a van, a laptop or a machine, and what it is worth on the books at every point.
- CPM, CPC and cost per conversion The four figures a campaign gets judged on, worked out at once, with what each one actually means. Because a low CPC with a bad CTR is not good news.
Pricing and margins
3 tools- Profit margin calculator Margin and markup come from the same two numbers and are not the same size. Here you get both at once, which is the only way to stop confusing them.
- Markup calculator Put a percentage on your cost and out comes the price. And next to it, the margin you actually keep, which is always smaller and almost nobody works out.
- Sales commission calculator Base pay, percentage, and the threshold where it starts counting. With the effective percentage at the end, which is the only way to compare two offers.
