Carrier Contract vs Spot Savings Calculator — Contract Rate ROI

Calculate annual savings from negotiated carrier contracts vs spot market. Model the impact of tender acceptance rates and fallback costs.

Quick answer: Contract rates typically run 15–35% below spot in a soft market. A 200-load/year lane at $2.45/mi contract vs $2.85 spot saves $64,000/year — if the carrier accepts tenders.

How to Use This Calculator

  1. Enter annual loads and miles — for this lane or carrier relationship.
  2. Enter spot and contract rates — compare load board rates vs your negotiated contract.
  3. Adjust tender acceptance — no carrier accepts 100% of tenders — factor in fallback loads to spot or secondary carriers.

Worked Example

200 loads, 800 miles, $2.85 spot, $2.45 contract, 90% acceptance, 20% fallback premium.

  1. Contract loads: 180 × $2.45 × 800 = $352,800
  2. Fallback: 20 × $2.94 × 800 = $47,040
  3. Total with contract: $399,840
  4. All-spot: $456,000
  5. Savings: $56,160/year

Monitor acceptance rates monthly. A carrier accepting only 70% of tenders erodes half the savings — adjust carrier mix accordingly.

Frequently Asked Questions

Negotiate when spot is high (carriers hungry for commitment), when you have 100+ loads/year on a lane, and when your freight characteristics are consistent. Accept spot when volume is sporadic or the market is very soft.

Contracts run 10–25% below spot in normal markets, 30–40% in soft markets. In tight markets, contract rates may be above spot — the value is guaranteed capacity, not cost savings.
