What Are ACH Payments?

The term ACH (Automated Clearing House) refers to electronic bank-to-bank transfers processed through the ACH network which is run by Nacha. This secure payment system handles billions of transactions annually, including direct deposits, bill payments, business-to-business (B2B) transfers, and person-to-person payments.

Typical ACH Fee Costs and Ranges

While ACH payments are generally much cheaper than credit card payments (which typically charge 2.5-3%) or wire transfers ($25-50), they aren't always free. Banks and payment processors may apply several types of fees to ACH transactions.

For basic business transfers, fees can vary widely depending on your provider, falling anywhere from free to more than 1% of the total transfer cost. These costs can add up quickly for businesses processing large volumes or high-dollar amounts. Let’s look at some common fee structures and the fine print your should look our for when choosing a provider.

11 Common ACH Fee Structures + What Providers Don't Tell You

1. Uncapped percentage-based fees: 0.5-1% of transaction value

Percentage fees scale with transaction size – convenient for small transfers but potentially expensive for larger ones. Some are capped, but not all. These are common with accounting software and payment platforms that target small businesses.

The fine print: Some major providers have recently removed caps on percentage fees, causing unexpected charges on large transfers. Historically, these might have been capped at $10 or $15 per transaction which is still high, but new account holders often face unlimited exposure.

As shown in the Reddit posts below, for businesses regularly processing large ACH transfers, uncapped percentage fees can cost thousands.

2. Flat-rate fees: $0.20-$1.50 per ACH transfer regardless of amount

Flat fees are straightforward – you pay the same amount whether transferring $100 or $100,000. This predictability makes budgeting easier and provides high value on larger transactions.

The fine print: These base rates may increase substantially for expedited processing, sometimes doubling or tripling for same-day service. Many providers also implement monthly minimum fee requirements – meaning if your transaction volume doesn't generate enough fees to meet the minimum (often $25-50), you'll be charged the difference anyway.

3. Platform subscription costs: $5-$50 monthly maintenance charges

Many providers with a low per-transfer fee charge monthly subscription fees just to maintain ACH capability, regardless of whether you process any transfers in a given month.

Hidden impact: These fixed costs dramatically increase your effective per-transaction rate when volume is low. A $25 monthly fee means that if you process just five ACH transfers that month, you're effectively paying an additional $5 per transaction – often far more than the advertised per-transaction rate.

For seasonal businesses with fluctuating payment volumes, these fixed monthly charges can make ACH prohibitively expensive during slower periods.

4. Account setup fees: One-time charges of $25-100 to enable ACH capabilities

Some providers charge initialization fees to activate ACH services, covering supposed account verification and risk assessment costs.

What providers don't advertise: These setup fees are often entirely negotiable or can be waived with minimal pushback. They exist primarily as profit centers rather than to cover actual costs, which is why sales representatives typically have authority to remove them upon request.

5. Limited or capped free transfer with overage fees

The rise of tiered pricing models has led many platforms to advertise "free ACH" while imposing strict monthly transaction limits.

The fine print: Exceeding these limits can trigger charges of $0.50+ per additional transfer, which quickly adds up for growing businesses. A company with 100 monthly vendor payments would incur $35-45 in overage fees on a plan with 10 free transfers – despite initially believing ACH was "free."

For example, Melio Payments, which previously offered unlimited free ACH, recently moved from unlimited free transfers to a tiered model allowing only 5 free ACH payments on its free plan, 20 on a $25/month plan, and 50 on a $55/month plan.

6. Volume tier pricing: Decreasing fees based on monthly transaction count

Some providers offer reduced per-transaction fees as volume increases – for example, $0.50 per ACH for the first 100, then $0.30 beyond that threshold.

Hidden threshold issues: These tiers often reset monthly, and failure to meet minimum volumes can trigger higher rates retroactively. Some agreements include clauses allowing providers to move customers to different pricing tiers based on their average volume, sometimes with minimal notice.

7. Extended processing times for free ach transfers

The standard ACH network operates on a next-day or two-day settlement schedule for most transactions, however, some payment platforms may have longer processing times of 3-5 business days.

Cash flow impact: While not directly a fee, these extended holding periods can affect your working capital. For businesses processing large ACH volumes, even a one-day delay in settlement can impact cash flow planning.

8. Expedited processing premiums: Same-day or next-day fees vary widely

When cash flow is tight or payments urgent, expedited processing seems like a reasonable premium service. Same-day ACH fees typically range from $1-10 for smaller transfers, though some providers may charge uncapped percentage-based fees for larger amounts.

What they don't mention: Many providers implement specific cut-off times (often before noon) for same-day processing requests. Submit after the deadline, and your "expedited" payment still takes an extra day – despite paying the premium fee.

9. NSF/return fees: $10-$35 when payments fail due to insufficient funds or account issues

When ACH transfers fail due to insufficient funds, closed accounts, or incorrect details, providers typically charge return fees to cover processing and handling. These fees can range from $10 at the low end to $35 or more at some major banks.

Important to note: Some providers may charge this fee to both parties involved in the transaction. This means you might pay a return fee for a failed collection attempt, and your customer could be charged as well – potentially affecting your business relationship when they realize your payment attempt resulted in an additional fee on their account.

10. Reversal/dispute charges: $5-$25 when transactions are contested

If a completed ACH transfer is disputed or reversed (similar to a credit card chargeback), most providers assess additional fees regardless of the outcome.

The fine print: These fees typically apply regardless of whether the dispute is valid or who initiated it. Even if your customer incorrectly disputes a legitimate charge, you bear the cost of the investigation.

11. Setup and integration costs: Charges for connecting ACH to your software systems

Many businesses need their ACH provider to connect with accounting software, ERP systems, or customer databases to maximize efficiency.

What's not obvious: These integration costs are often bundled into other fees rather than presented transparently. A "free setup" might actually include integration limitations that require expensive upgrades to overcome.

Why ACH Processors Add Fees

Now that we’ve looked at some of the common fee structures, lets look at some of the costs associated with processing ACH transactions that payment providers face.

Bank network costs

Financial institutions must maintain connections to the ACH network governed by NACHA (National Automated Clearing House Association). While there are legitimate costs associated with this infrastructure, the actual processing cost through the Federal Reserve system is typically only a few cents or less per transaction—far less than what most providers charge.

Risk and fraud management

Unlike credit card transactions, ACH transfers can be returned or reversed due to insufficient funds or fraud claims. Providers need systems to manage this risk, but even accounting for occasional losses, the average fraud cost is minimal.

For example, according to BILL's 2021 S-1 filing, fraud-related losses were less than 1 basis point (0.01%) of total payment volume in FY18 and FY19. While the company no longer breaks out fraud losses separately, recent financials suggest these losses remain relatively low.

Middlemen and processing layers

Many payment processors don't connect directly to the ACH network. Instead, they operate through multiple intermediaries:

• Your payment processor (the platform you interact with)
• One or more wholesale payment providers
• Sometimes additional aggregators for smaller volumes
• Finally, a sponsoring bank that actually accesses the ACH network

Each layer adds costs and markup. This distribution chain approach not only increases fees but creates visibility issues—when payment problems arise, your provider may not even know where a transaction is stuck because they're several steps removed from the actual processing.

Service and infrastructure

Maintaining the technology infrastructure to process ACH transactions securely does require investment. Banks must convert complex NACHA files into user-friendly interfaces, provide customer support, and ensure compliance with regulations. However, many providers use these legitimate costs to justify charging far beyond what's necessary.

Profit margin

The uncomfortable truth is that many providers charge uncapped fees of 1% or more for ACH transfers simply because they can. With actual costs measured in cents rather than percentages, these fees represent significant profit centers rather than necessary charges.

How to Lower or Eliminate Your ACH Fees

Now that you understand why processors charge these fees – and how much of them are simply profit margin rather than actual costs – let's explore practical approaches to minimize or eliminate these expenses from your business.

Use Bank-Direct ACH When Feasible

Many business banking relationships include ACH transfer capabilities at low or no cost. While these bank portals often lack the integration and automation of specialized platforms, they can be cost-effective for certain payment types.

Best for:

• Regular, predictable vendor payments
• High-dollar transfers where percentage fees would be substantial
• Payments that don't require integration with your accounting system

The drawback: Using bank-direct ACH typically requires giving bank access to a limited number of employees (usually just the business owner or CFO), creating potential bottlenecks in your payment process.

Negotiate Based on Volume

If you process substantial ACH volume, you have leverage to negotiate better rates. Many providers have flexibility in their pricing but only adjust it when customers actively push for better terms.

Effective negotiation points:

• Your total monthly/annual ACH volume
• Average transaction size
• Your history as a reliable customer
• Competitive offers from other providers

Batch Payments Strategically

If your provider charges per-transaction fees, consolidating multiple payments can yield significant savings. Instead of processing individual transfers daily, consider batching payments to the same recipient.

For example, if you typically pay a supplier weekly and incur a $0.50 fee each time, switching to monthly payments reduces your annual fees from $26 to $6 per vendor – a 77% savings.

This approach works particularly well with:

• Regular supplier payments
• Recurring service provider bills
• Partner or affiliate payments

Switch to a No-Fee Provider like Nickel

Consider moving your ACH processing to a platform with minimal or no fees. Several modern fintech providers, including Nickel, have created more efficient ACH transfer systems that can offer significantly reduced or eliminated fees.

This approach offers several advantages:

• Substantial reduction or elimination of ACH fees
• Simpler fee structure with fewer variables to monitor
• Simplified accounting without tracking transaction costs
• Freedom to process payments based on business needs rather than fee optimization

For businesses processing dozens or hundreds of ACH transactions monthly, switching to a lower-fee provider can save thousands annually – money that drops directly to your bottom line.

But this raises an important question: If ACH transfers cost so little to process, how can some providers offer them at minimal or no cost while others charge substantial fees? Let's explore how this is possible.

How Nickel's Unlimited Free ACH Transfers Work

You might be wondering: if other providers charge substantial fees for ACH transfers, how can Nickel sustainably offer them for free? Is there a catch?

The answer reveals a lot about how the ACH system works – and why many businesses have been unnecessarily overpaying for these transfers.

Direct Banking Connections

As we discussed earlier, many payment platforms don't connect directly to the ACH network. Instead, they operate through layers of intermediaries.

Nickel takes a fundamentally different approach by establishing direct connections to banking partners and the ACH network. This direct-to-consumer model (think how Casper revolutionized mattress sales by cutting out middlemen) eliminates unnecessary markups and creates a more efficient system with:

• Faster processing times
• Higher reliability
• Complete visibility into payment status
• Significantly lower operational costs and risk

Take Control of Your ACH Payment Fees Today

Now that you understand both the issue and the solutions, you can take action:

• Recognize that many ACH fees include profit margin above the actual processing costs
• Implement strategies to reduce these fees where possible
• Consider switching to a lower-cost or potentially fee-free provider like Nickel for a simpler approach

A business processing $50,000 monthly in ACH transfers paying a 1% fee could save $500 every month by finding a provider with flat-rate pricing – that's $6,000 annually that stays in your business.

Take these three steps to start reducing or eliminating your ACH fees:

1. Audit your current ACH payment costs and identify all hidden fees
2. Implement the cost-reduction strategies outlined in this guide
3. Evaluate no-fee providers like Nickel that offer completely free ACH transfers

Calculate what you're currently spending on ACH fees. If it's more than zero, it's worth exploring alternatives. Your bottom line will thank you.
