What this calculator does
One overdraft can cause multiple pending transactions to bounce. This calculator adds the base bounce fee plus per-transaction NSF fees.
The math
Total damage = base bounce fee + pending transactions × NSF fee per transaction.
Worked example
A $35 bounce fee plus 3 pending transactions at $35 each totals $140.
Why this matters
