Free Shipping Threshold Calculator
Customers expect free shipping, but covering that cost can eat your margin. Enter your current AOV, average shipping cost, profit margins, and absorption limits to find the sweet spot where free shipping lifts AOV without killing profitability. You get a minimum safe threshold, a recommended threshold, and the incremental profit at that level.

How it works
Methodology & formulas
This calculator is transparent by design. Review the steps and formulas so you can trust the estimate and adjust assumptions when your dashboard differs.
Calculation steps
- 1Margin-based threshold = avgShippingCost / ((avgProfitMargin - targetProfitMargin)/100).
- 2Absorption-based threshold = avgShippingCost / (shippingCostAsPercent/100).
- 3Minimum safe is max of both methods to protect margin.
- 4Recommended threshold rounds minimum safe up to nearest $5 or $10 for shopper psychology.
- 5Profit at threshold = threshold * targetProfitMargin% gets absolute profit dollars.
- 6Incremental profit per order = (threshold * targetMargin%) - (currentAOV * (avgMargin% - shipping% at current)).
Formulas
- Margin threshold = shippingCost / (avgMargin - targetMargin)
- Absorption threshold = shippingCost / (shippingPercentAtThreshold)
- Minimum safe = max(marginThreshold, absorptionThreshold)
- Recommended = ceilToFriendly(minimumSafe)
- Profit at threshold = recommendedThreshold × targetMargin%
Important assumptions
- Average shipping cost stays same per order regardless of threshold level.
- Threshold based on margin protection method: threshold = shipping / (avgMargin - targetMargin).
- Secondary check uses shipping absorption percent: threshold = shipping / (shippingCostAsPercentOfOrder%).
- Recommended threshold is max of the two methods rounded to a shopper-friendly number.
- Incremental profit assumes customer reaches threshold and shipping cost unchanged.
Worked example
