Attached is an image version of the 2020 postage chart I made. Please feel free to use / print it out if you find this useful.
$1.07 is stamp rate if you're only purchasing one stamp over the counter.
These are all OVER THE COUNTER rates, so if you have Solution for Small Business account (or if you print via Shippo or Paypal) you will get cheaper rates for the parcels. Definitely use Shippo/Paypal/CPC online for Tracked Packet since the saving is quite significant (at least 10% cheaper). Fuel surcharge fluctuations apply to Tracked Packet.
For Small Packet rate, I used United Kingdom and Australia as reference since that's what I use often. As you can see, for the <250g and <500g weight bracket, depending on your international destination, it might be cheaper to use small packet air instead of letter-mail.
I did not include rates for expedited parcel, xpresspost, priority etc in the chart because the price varies greatly depending on both sender and receiver location.
