Frequently Asked Questions

What's the difference between profit margin and markup on cost?

Profit margin is profit as a percentage of your selling price. Markup on cost is profit as a percentage of your production cost. The two numbers are related but not the same: a 50% markup does not equal a 50% margin.

Why does rent and other overhead get added to a single job?

Every hour your premises are in use costs you rent, rates, utilities and other overheads, whether or not you're actively producing. This calculator spreads those monthly costs across your working hours and allocates a fair share to each job, so your pricing accounts for overheads and not just materials and labour.

What's the break-even selling price?

It's the price at which your revenue exactly covers your total production cost (direct costs plus your allocated share of overheads), with zero profit. Selling below this price means making a loss on the job.

How is "premises hours used" different from labour cost?

Labour cost is what you pay someone for their time. Premises hours used is how long the job occupies your workshop or business premises, which is what drives how much rent, utilities and other overheads should be allocated to it.

How often should I review my prices?

We recommend reviewing your pricing at least once or twice a year, or whenever your costs change significantly, for example when supplier prices rise or your overheads increase.
