Frequently Asked Questions

Should I charge renters for blade and bit wear?

Yes. Consumable wear is a real cost that adds up quickly. A $30 saw blade that lasts 10 rentals costs you $3 per rental. Across your fleet, consumable costs can add up to hundreds per month. Either build the cost into your rental rate or add it as a transparent line item. Most renters understand and expect consumable charges.

What markup should I add to consumable charges?

Industry standard is 30-75% markup on consumable charges. This covers not just the cost of the consumable itself but also the labor to inspect and replace it between rentals. A 50% markup is a good starting point. For expensive items like specialty saw blades, you can go lower (30%). For cheap items like sandpaper, go higher (75%).

How do I track consumable usage across my tool inventory?

The simplest method is to inspect consumables at every tool return and log whether replacement was needed. Over time, this gives you accurate averages for each tool type. Track the data in your rental management system or a spreadsheet with columns for tool ID, consumable type, replacement date, and cost.
