How to use this calculator

  1. Enter your numbers in each field above — the calculator updates instantly as you type, so there's nothing to submit.
  2. Use your real figures when you have them, or sensible estimates while you're planning. If a field doesn't apply, leave it at zero.
  3. Compare the results, then change one input at a time to see how each lever (price, cost, fees, volume) moves the outcome.

Formula

True cost = Postage + Packaging + (Minutes ÷ 60 × Hourly) + (Charged × Fee%) · Per order = Charged − True cost · Monthly = Per order × Orders

Worked example

$5 charged, $4.50 postage, $1.20 packaging, 8 min at $20/hr, 10% fee, 40 orders.

  1. Handling = 0.133 × 20 = $2.67
  2. Fee on ship = $0.50
  3. True cost = 4.50 + 1.20 + 2.67 + 0.50 = $8.87
  4. Per order = 5 − 8.87 = −$3.87

Answer: Losing $3.87 per order → $154.80/month

How it works

Handling time is where most sellers underestimate — 8 minutes per order isn't free, and at scale it dominates. Under-charging shipping is one of the fastest hidden profit leaks.

How to interpret your results

  • Dollar values are shown per sale, per order, or per item unless a result is explicitly labelled monthly, weekly, or daily.
  • Percentages (margin, ROI, conversion rate) are easier to compare across products and price points than raw dollars — use them when you benchmark.
  • A positive result means you're ahead after the costs and fees you entered. A negative result means the current numbers don't work — change a lever (raise price, cut a cost, lower ad spend) and recalculate.
  • Treat the output as a planning estimate, not a guarantee. Fees, taxes, and conversion rates shift over time — re-run the numbers whenever a key input changes.

Common mistakes

  • Skipping handling time.
  • Forgetting the platform fee on the shipping charge.
  • Only checking postage without packaging.

FAQ

Should shipping break even or profit?
Break-even including handling is the honest target. Turning shipping into a profit line is unusual.
How is this different from Shipping Price Calculator?
This one isolates the shipping line. Shipping Price prices the item so the entire order is profitable.
