Scored on 69 merchant reviews we hold for Calcurates: Accurate Shipping, across five checks. Every figure is computed from those reviews — expand any row to see the counts behind it.





Computed from the 69 reviews we hold, with 12-month windows measured to 2026-09. This scores the public review record — it is not a review of the software itself, and a low score often means we hold little evidence rather than poor evidence.

The newest 8 of 75. Open one to read it in full, with the developer's reply where there is one.

Having used various shipping rate calculators over the years, this is hands-down the most advanced, accurate, and user-friendly app available. We always struggled to find a tool that could calculate cubic weight accurately, but this app handles it effortlessly. The layout and UX are outstanding—setting up complex, custom rules for our business is simple and stress-free, replacing what used to be a very frustrating process on other platforms.

Developer repliedWow, thank you for this! Really glad Calcurates is solving the cubic weight problem for you — that's exactly the kind of accuracy gap we set out to close. And it's great to hear the custom rule setup feels simple rather than stressful — that's what we're always aiming for. Appreciate you taking the time to share this! Show more

Calcurates is an extremely configurable shipping app that allows us to define exactly how different products should be packed into boxes. This gives us far more accurate shipping calculations and allows us to pass precise shipping costs on to our customers rather than relying on estimates. The Calcurates team has also been very helpful in working through our more complex packing scenarios and assisting with the setup. It is a powerful solution for businesses that need greater control over packaging and shipping rates.

Developer repliedThank you for the kind words! We're glad Calcurates Smart Packaging is helping you deliver more accurate shipping costs to your customers. Great to hear our team could help you work through the trickier packing scenarios — we're always here if new challenges pop up. Show more

Developer repliedThank you for the great feedback! We’re glad Calcurates is helping you save on shipping and improve transparency for your customers. We truly appreciate your kind words about our support — always here to help! Show more

Nik and his team have been fantastic in helping us set up numerous complicated shipping rules for our store, not an easy task! It has completely changed our way of working, we cannot thank him enough! Nik is very responsive if we have questions, and always happy to help. Cannot recommend Calcurates enough.
