Frequently Asked Questions

What is a good profit margin for party rentals?

Healthy party rental margins range from 60-80% on individual items. Chairs and tables typically hit 70-85% margins because they're durable and cheap to maintain. Linens and delicate decor items often have lower margins (40-60%) due to higher cleaning costs and replacement rates. If any item falls below 40%, reconsider your pricing.

How do I account for replacement costs?

Track how many items of each type you replace per year due to damage, stains, or loss. Divide that by your total inventory of that item to get your replacement rate. For chairs, expect 2-5% annually. For linens, 10-20%. For glassware, 8-15%. Factor this into every rental to build a replacement fund.

Should I include delivery costs in my margin calculation?

If you charge separately for delivery, keep it out of the item margin calculation. If delivery is included in the rental price, you should factor in the per-item delivery cost. Most party rental businesses charge delivery separately, which keeps item margins cleaner and more accurate.
