How do you price international shipping without losing money?
I'm based in the UK and keep getting orders from the US, Canada and Australia. Every time I ship internationally I end up undercharging because I guessed the weight wrong or forgot to account for packaging. I'm losing £3–6 per international order. How do you accurately calculate international shipping upfront without just guessing?

Get a digital kitchen scale and weigh everything including your packaging materials — box, tissue paper, tape, inserts. Then check the actual carrier rates (Royal Mail for UK, with zone-specific pricing for US/CA/AU) at your exact weights. Build in a 10–15% buffer to account for dimensional weight surcharges. I've used a spreadsheet with all my item + packaging weights for a year now and I've stopped losing money on international orders.
The mistake most people make is forgetting dimensional weight. Carriers charge based on whichever is higher — actual weight or dimensional weight (length × width × height / a divisor). A light but bulky package can cost significantly more than its actual weight suggests. Run your typical packages through the carrier's online calculator with actual measurements.
Consider setting international shipping as a flat rate slightly above your average actual cost. It means you occasionally overcharge by a little and occasionally undercharge a little, but it averages out and saves you the mental effort of recalculating every order. Make sure your flat rate reflects your heaviest typical item, not your lightest.
