In-Depth Analysis — Stripe 2.9% + $0.30 Fee Guide
A common accounting mistake when passing credit card fees to clients is simply adding 2.9% + $0.30 to the invoice ($1,029.30)—because Stripe then takes 2.9% of that higher total, leaving you short ($999.15).
The exact reverse gross-up equation is Gross Invoice = (Target Net + $0.30) / (1 − 0.029), which equals $1,030.18 on a $1,000 net target.
