Standard Direct Deposit Runs on ACH
Most lenders fund through the ACH (Automated Clearing House) network, which processes in scheduled batches during the business day rather than continuously. Approval before a bank's daily cutoff can mean same-day deposit; approval after it typically pushes the deposit to the next business day, regardless of how quickly the lender approved you.
Instant Transfer Runs on RTP or FedNow
A smaller but growing number of lenders offer funding through RTP (Real-Time Payments) or FedNow, both of which can move money within seconds to minutes, 24/7, including weekends and holidays — something ACH cannot do. This speed usually comes with a fee, and both the sending and receiving bank need to support the rail for it to work end to end.
Why "Fast" Isn't the Same Guarantee Everywhere
A lender advertising "fast funding" might mean same-business-day ACH, or might mean genuine instant transfer — these are very different experiences if you need money outside business hours. It's worth asking, or checking the lender's disclosed funding method, before assuming a Friday-night approval means Friday-night money.

| Cost | Usually included, no extra fee | Often an added fee |
| Availability | Universal — every bank supports ACH | Requires both banks to support the rail |
