# Calculating international postage with USPS Forever stamps

20 Sep 2015 in Standalone

I just spent ages trying to work this out, so here's a quick post to remind myself should it ever come up again:

The current value of a Forever stamp is 49 cents at time of writing (check current value with this search)

The USPS have an online calculator to work out postage values located here

To send a post card (with a value of $0) it costs $1.20 per card, or 3x Forever stamps

To send a rectangular letter (i.e. birthday card) weighing 1oz or less (with a value of $0) it costs $1.20 per letter, or 3x Forever stamps

You can legally use multiple Forever stamps on a single item of post to ensure that the postage cost is covered.
