Most payment programs treat speed as a cost. The ACH standard costs $0.30. Same-day ACH costs $1.50. RTP costs $0.045 plus markup. The program optimizes for the cheapest delivery option that meets the SLA, and the difference in rail cost disappears into overhead.
This is the wrong frame. Settlement speed is a product — and the difference between what faster settlement costs to deliver and what it's worth to the receiver is a margin opportunity that most programs never capture.
The receiver's problem isn't your cost structure
A contractor waiting on a payroll disbursement doesn't care what the ACH fee is. They care when the money arrives. A supplier with a $400,000 invoice due on Friday afternoon cares whether it settles before the weekend or on Monday. The value of same-day versus next-day settlement isn't measured against your rail cost — it's measured against the cost of the delay to the recipient.
For B2B payees, same-day settlement has a specific economic value: avoided short-term borrowing, working capital freed, supplier relationship maintained. For consumer payees, instant disbursement has a different value: utility bills paid today, car repair covered now. Both are worth more than the $1.20 spread between standard ACH and same-day ACH.
Three models for monetizing speed
There are three ways to turn delivery speed into revenue. Each has a different buyer, a different pricing mechanism, and a different fit by program type.
Transactional speed premium. The simplest model: charge per transaction for faster delivery. Standard ACH is the baseline. Same-day ACH is a premium. Instant (RTP or FedNow) is a higher premium. The pricing ladder should reflect the rail cost difference plus a meaningful margin — not just the rail cost. Programs that price same-day delivery at rail cost are delivering a product at cost of goods.
Subscription speed tier. Bundle faster delivery into a paid tier. The payer pays a flat monthly fee for same-day or instant delivery on all transactions. This model works well when the payer has predictable volume and wants simplicity. It also creates a recurring revenue line that doesn't fluctuate with transaction volume.
Speed embedded in platform tier pricing. For SaaS platforms with embedded payments, faster delivery speed can be a feature that differentiates higher-priced subscription tiers. The payment speed becomes part of the platform value proposition, not a separate payment charge. The economics are the same — the program captures the spread — but the pricing is invisible to the end customer.
The cascade economics
A multi-rail program that prices speed correctly generates revenue from the cascade itself. The cost of routing a transaction over RTP versus ACH might be $0.05 difference. The price premium for instant delivery might be $2.00. The spread is $1.95 per transaction.
At $10M in monthly processing volume with an average transaction size of $2,000, that's roughly 5,000 transactions per month. If 30% of payers elect instant delivery, that's 1,500 transactions at $1.95 margin each — $2,925 per month from speed premiums alone, on a program that previously captured none of it.
The arithmetic scales. Programs with $100M in monthly volume can generate $250,000+ in annual speed premium revenue from a pricing change that takes one contract update to implement.
What blocks programs from capturing this
Two things block programs from capturing speed revenue. First, the product was designed to optimize for cost, not revenue. Speed options are offered but priced at or near rail cost because the framing was "what does this cost us" rather than "what is this worth to the receiver."
Second, the infrastructure wasn't designed for routing intelligence. If your program routes all transactions over ACH by default because that's what the first BaaS integration supports, there's no mechanism to detect which payees would benefit from faster delivery — and no rails in the cascade to deliver it even if you wanted to charge for it.
Both problems are architecture problems. They're fixed at the design stage, not the pricing stage.
Designing for speed revenue
The program architecture for speed revenue requires three things to be defined before the build: the rail mix (which rails the program offers for delivery), the cascade logic (how the program decides which rail to use for each transaction), and the pricing structure (how speed tiers map to price tiers and who has the option to elect them).
None of this can be retrofitted easily. The rail agreements, infrastructure integrations, and pricing mechanics all need to be part of the initial program design. Programs that didn't design for speed revenue from the beginning spend significantly more to add it post-launch — if they add it at all.
