Find the 3PL Order-Volume Break-Even
Estimated monthly crossover
900 orders
Above or below this point, compare both full monthly cost lines against your latest invoices.
- Self-fulfilment at crossover
- $6,500.00
- 3PL at crossover
- $6,500.00
- Formula
- (self fixed − 3PL fixed) ÷ (3PL per order − self per order)
This model includes only the four visible inputs. It does not infer storage minimums, pick tiers, returns, packaging, tax, or service-level differences. Reconcile assumptions against current contracts and invoices.
How to use this tool›
Find the 3PL Order-Volume Break-Even
- Use costs from the same month and currency. Separate fixed monthly charges from costs that scale with each order.
- Enter self-fulfilment and 3PL costs per order, including only the charges you intend this model to compare.
- Read the crossover as an estimated monthly order threshold, then compare both cost lines with recent invoices.
Example
With $2,000 self fixed cost, $200 3PL fixed cost, $5 per self-fulfilled order and $7 per 3PL order, the cost lines cross at 900 orders per month.
