About Shipping Cost Threshold Calculator

The break-even order value for free shipping is the shipping cost divided by gross margin. Adding a contribution target raises the threshold, and setting it above current average order value is what makes customers add items.

Formula

Shipping threshold

Break-even = shipping cost / gross margin; threshold = shipping cost / (margin - target contribution)

Worked example

With the default values below, Shipping Cost Threshold Calculator returns Recommended Free Shipping Threshold of $1,185.19. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

  • The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax or compounding frequency into account.
  • Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
  • Figures are estimates based on the inputs given. Marketing performance, platform fees and conversion behaviour vary by audience, channel and season. Use this as a planning guide, not a forecast.
  • This is an estimate for general information and not professional financial, tax or legal advice. See the full disclaimer for the limits that apply to this kind of calculator.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Should the threshold sit above average order value?

Yes, typically 20-30% above, so it changes behaviour rather than simply giving away margin.

What if shipping cost varies by weight?

Use a weighted average, or set zone-based thresholds where the variation is large.
