A simple tool to help you estimate suite weights, calculate postage rates, and simplify invitation mailing for client projects.

Postage Calculator

If you’ve ever manually weighed invitation suites, searched USPS charts, and second-guessed whether your postage was correct… you’re not alone.

Luxury invitation suites can become surprisingly complicated once ribbon, wax seals, layered cards, vellum, and embellishments enter the equation. And calculating postage for every variation manually can quickly become frustrating.

The Postage Calculator helps simplify the behind-the-scenes logistics of mailing embellished invitation suites by automatically estimating suite weights and postage categories for common USPS mailing scenarios.

Because invitation assembly is already detailed enough without manually calculating postage for every project.

Save time.
Reduce postage surprises.
Simplify mailing.

Use the exact postage calculator we built for our own stationery business to estimate suite weights, simplify mailing, and reduce postage guesswork for every client project

Yes. The calculator includes current USPS pricing rates at the time of purchase based on the latest adjustments from July 2025. Rates will be increasing again in July 2026. 

Because postage rates may change over time, we always recommend confirming final postage directly with USPS before mailing client suites.

Does this use current USPS rates?

The calculator helps estimate: invitation suite weights, mailing classifications, estimated postage rates, based on your selected materials and embellishments.

What does the calculator estimate?

Yes, in the areas designed for customization. The yellow cells are where you’ll add your own project inputs, and the postage rate chart can be updated as USPS rates change.

Certain formula cells are locked to protect the calculations and help make sure the calculator continues working correctly.

Can I customize the calculator?

Once purchased, the Postage Calculator will be added directly to your Learn with Elisabeth student portal. If you already have an account, it will appear inside your existing dashboard automatically.

How will I access the calculator?

Absolutely. The calculator was designed to simplify postage calculations whether you’re newer to luxury stationery or already mailing embellished suites regularly

Inside the portal, you'll receive: 
  • a Google Sheets version with a "make a copy" link
  • an Excel version for desktop users

Please note that international postage rates may vary slightly depending on destination country and USPS classification requirements.
