0.5% is immaterial for subscription-based businesses where profit margins are typically the highest.

But... it adds up.

For example, just looking at the last $39 USD transaction in my Stripe dashboard which gets converted to $53.72 AUD (I charge in USD but receive AUD)

Stripe currency conversion fee: $0.88 Stripe processing fees: $1.69 Total: $2.57

That's 4.78% fee. Now add this new 0.5% and we are over 5% fee on transaction processing.

Is this expensive enough for me to consider alternatives? No.
