How much is Santander’s overdraft fee? Santander charges $15 per item when it pays a transaction that overdraws your account by more than $100. The Santander Safety Net means an overdraft of $100 or less costs nothing, and per-item fees are capped at three a day. Santander does not charge a fee when it returns an item unpaid.

How much does a Santander overdraft cost?
Santander calls its per-item charge the Insufficient Funds Fee, and it runs $15. That fee only applies once a paid transaction leaves your account overdrawn by more than $100. Santander limits itself to 3 of these fees a day, so the most in per-item overdraft fees a single day can cost is $45. A separate Sustained Overdraft Fee can still apply on top. If an item is paid against a deposit that has not cleared yet, or if Santander returns an item unpaid, there is no fee either way.
The Santander Safety Net: a $100 cushion
As long as a transaction leaves your account overdrawn by $100 or less, Santander will not charge the $15 fee. Only once a paid item pushes your balance more than $100 negative does the fee apply, up to the 3-per-day cap.
The Sustained Overdraft Fee
If your account ends the first business day more than $100 overdrawn, and then stays negative by any amount for five consecutive business days, Santander adds one extra $15 Sustained Overdraft Fee on the sixth business day. You do not have to stay more than $100 negative for the whole stretch. Day one must clear that bar. Days two through five only need a negative balance. This fee is separate from, and in addition to, per-item fees.
Does Santander charge a returned-item (NSF) fee?
No. When Santander returns an item unpaid instead of covering it, that return costs nothing. If an Insufficient Funds Fee was already charged for that same item before the return decision, Santander refunds it.
Overdraft protection transfers
You can link a Santander checking, savings, or money market savings account. Santander transfers funds when the total overdrawn balance is available in your linked account(s) and none of those accounts are also overdrawn. There is no Overdraft Protection Transfer Fee. Santander limits withdrawals and transfers out of savings and money market savings accounts, and an overdraft protection transfer counts toward that limit.
Which transactions can overdraw your account?
When you open a Santander checking account, you choose SOME Overdrafts or ALL Overdrafts. Under the SOME Overdrafts election, ATM withdrawals and one-time debit card purchases are generally declined at no fee when funds are short. Checks, ACH payments, and recurring transactions can still be paid into overdraft or returned, with the $100 threshold applying to paid items.
| Transaction type | What happens if funds are short |
|---|---|
| ATM withdrawal (SOME Overdrafts election) | Generally declined at the machine, no cash dispensed, no fee |
| Everyday debit card purchase (SOME Overdrafts election) | Generally declined at checkout, no fee |
| Checks and ACH payments | May be paid (fee if overdrawn more than $100) or returned unpaid (no fee) |
| Recurring debit card payments | May be paid (fee if overdrawn more than $100) or returned unpaid (no fee) |
A declined debit card purchase costs nothing at Santander, but the purchase does not go through. A returned check can still trigger a late fee from whoever you owed.
How to avoid Santander overdraft fees
- Use the Safety Net. Staying within $100 of zero means no per-item fee.
- Watch the sustained-fee clock. If day one ends more than $100 overdrawn, bring the balance to $0 or above within five business days so the day-six $15 charge does not land.
- Set up account alerts for a low or negative balance.
- Link a backup deposit account. The overdraft protection transfer itself is free.
- Choose your overdraft election. Decide whether you want ATM and one-time debit transactions paid or declined.
Short before payday? If the alternative is stacking bank fees, a small advance can be cheaper when you qualify and repay on time.

Compare cash advance apps that can cover a shortfall. If you keep landing in overdraft, an app that fronts you a small amount until payday may cost less than repeat bank fees.
