How to Use This Calculator

Enter monthly loads and capacity gap — what % of loads can't be covered by contracted carriers and go to spot?
Enter contract rate and spot premium — the extra cost per load when forced to use spot market.
Use result to justify contract coverage — if the annual shortage cost exceeds the cost of securing additional contract coverage, the case is clear.

Worked Example

120 loads/month, 25% gap, $2,400 contract rate, 35% spot premium, 12% delays at $250 chargeback, $65 admin.

Spot loads: 30/month
Spot premium/yr: $302,400
Chargebacks/yr: $43,200
Admin/yr: $23,400
Total: $369,000/yr

A $369K annual cost of capacity shortage. Securing 25 more loads/month on contract at even a 5% rate premium costs $172,800/year — saving $196,200. The math for building carrier relationships is clear.
