5% flat" sounds simple. On a $5 tip, it isn't the whole story

Buy Me a Coffee's pitch is refreshingly simple compared to most of this list: no monthly fee, no tiers to decode — just a flat 5% platform fee on every coffee, membership, or shop sale. What the flat rate hides is the Stripe processing fee sitting underneath it, which behaves very differently on a $3 tip than on a $50 membership payment.

What Buy Me a Coffee doesn't spell out on the pricing page

• Platform fee: 5% flat on every transaction — tips, memberships, and shop sales alike, with no volume discount and no paid tier to reduce it.

• Payment processing: handled through Stripe Standard Connect underneath the platform fee — Stripe's own $0.30 fixed fee applies on top, which barely dents a $50 membership charge but takes a real bite out of a $3-5 tip.

• The two fees compound differently by transaction size: on small tips, the fixed $0.30 dominates the loss; on larger memberships or shop purchases, the 5% platform cut is the bigger factor. Buy Me a Coffee's dashboard shows the deduction but not this size-dependent breakdown.

• Payouts: arrive in weekly or monthly batches rather than instantly, which matters if you're reconciling revenue against a specific date.

Worked example

A $5 coffee tip: 5% platform fee ($0.25) + Stripe processing (~2.9% + $0.30 ≈ $0.45) = ~$0.70 in combined fees → you keep about $4.30, an effective rate of roughly 14%. A $50 membership payment: 5% platform fee ($2.50) + Stripe processing (~2.9% + $0.30 ≈ $1.75) = ~$4.25 in fees → you keep about $45.75, an effective rate of roughly 8.5%.

The takeaway: your real take-home rate on Buy Me a Coffee depends heavily on your average transaction size, something the flat "5%" headline doesn't communicate.

How it works

• Read-only connection to your Buy Me a Coffee account.

• Transaction pull with platform fee and underlying Stripe processing fee broken out separately.

• Net revenue shown alongside your other creator income — useful if you also run Patreon memberships or sell digital products on Gumroad with very different fee curves.
