How to Use This Calculator

Enter annual customs duty — total duty paid to CBP over the last 12 months.
Enter average dwell days — how long goods typically stay in bond before being withdrawn for consumption or re-export.
Set cost of capital — your WACC or borrowing rate — this is the value of not paying duty upfront.

Worked Example

$500K annual duty, 90-day avg dwell, 8% cost of capital, 10% re-export, $18K bonded premium.

Avg deferred duty: $500K × 90/365 = $123,288
Cash flow saving: $123,288 × 8% = $9,863
Duty eliminated (10%): $50,000
Total benefit: $59,863
Net after bonded premium: $41,863/year

The re-export duty elimination is usually the bigger driver. If you re-ship 10%+ of goods internationally without US consumption, bonded warehousing eliminates that duty entirely — often 5–10x the cash flow benefit alone.
