The honest threshold: 7–10% of daily revenue
There's no regulatory rule about how large an MCA payment can be. But there's a practical threshold that separates affordable from dangerous: your daily ACH withdrawal should be no more than 7–10% of your average daily revenue.
Below 7% — you have room to breathe. Slow days, equipment issues, a slow week don't threaten your operating stability.
7–10% — manageable if your revenue is consistent and your margins are solid. You're leaving yourself limited buffer.
Above 10% — you're in trouble. Every slow day means you're covering the ACH from cash that should be going to payroll, rent, or cost of goods. The math starts compounding against you.
Calculator examples: three businesses
Let's run the numbers for three real business types. All examples assume a 1.30 factor and a 12-month term (roughly 252 business days).
Restaurant: $1,500/day average revenue
- 7% threshold:
$1,500 × 0.07 = $105/daymax daily ACH - 10% threshold:
$1,500 × 0.10 = $150/day - Max advance at 7% threshold: Daily ACH of $105 × 252 days = $26,460 total payback. At 1.30 factor:
$26,460 ÷ 1.30 = ~$20,350 funded - Max advance at 10% threshold: $150/day → $37,800 payback →
~$29,000 funded
If a funder is offering you $45K for a restaurant at $1,500/day — that's a daily ACH of ~$232/day, or 15.5% of daily revenue. That's not a capital solution. That's a debt spiral waiting to happen.
Trucking company: $3,000/day average revenue
- 7% threshold:
$3,000 × 0.07 = $210/daymax daily ACH - Max advance at 7%: $210 × 252 = $52,920 payback →
~$40,700 funded - Max advance at 10%: $300/day → $75,600 payback →
~$58,150 funded
Trucking has lumpy revenue — fuel costs, slow load weeks, deadhead miles. A $40K advance at 7% gives you the operating cushion to absorb a $10K slow week without going negative.
Retail store: $800/day average revenue
- 7% threshold:
$800 × 0.07 = $56/daymax daily ACH - Max advance at 7%: $56 × 252 = $14,112 payback →
~$10,855 funded - Max advance at 10%: $80/day → $20,160 payback →
~$15,500 funded
A retail store at $800/day average should be looking at a $10–$15K advance maximum on a 12-month term. If a broker is offering you $35K, ask what the daily ACH would be — and then divide by 800. If that number is above 10%, the offer is too large for your revenue base.
Why the 7% rule matters: the slow-day problem
Average daily revenue is a smooth number. Real business revenue is lumpy. Your restaurant does $2,400 on a Saturday and $700 on a Monday. Your trucking company does $5,500 with a good load and $800 on a repositioning day. Your retail store does $1,200 before a local event and $300 the week after.
The MCA ACH doesn't care about any of that. It pulls the same amount every business day regardless of what you deposited. If your daily ACH is sized for your average day, your worst days will go negative — triggering NSFs, triggering bank fees, and making the next 90 days of bank statements look terrible.
Sizing at 7% of average revenue means even a day that comes in at 50% of average still covers the ACH with room to spare. That's the buffer you need.
The double whammy: why over-sized advances lead to stacking
Here's the sequence that precedes nearly every small-business MCA default:
- Business takes an MCA that's too large — daily ACH at 12–15% of daily revenue.
- Cash flow tightens. Payroll is late. Vendor payments get delayed. Credit card minimum payments are skipped.
- Owner calls the broker for relief. Broker's answer: "Let me get you a second advance to cover the gaps." That's stacking.
- Now two daily ACH payments are running — combined 20–25% of daily revenue. The business has no operating cash left.
- NSFs start. The original funder notices. Default proceeds.
The fix is at step 1: size the first advance correctly, and stacking never becomes tempting.
Weekly ACH: when it helps
Some A-paper funders — notably Credibly and OnDeck — offer weekly ACH as an option for better-tier merchants. For revenue-volatile businesses, this can help: you accumulate 5 days of revenue before the ACH hits, which smooths out the lumpiness.
The caution: weekly ACH on a 12-month term means your ACH is 5× the daily equivalent. Make sure you have a weekly revenue floor that comfortably covers it. If your worst week generates $3,500 and your weekly ACH is $1,100, you're okay. If your worst week generates $1,400, you're dangerously close to NSF territory.
What to do if you're already over the threshold
If you're already in an MCA where the daily ACH is eating more than 10% of your daily revenue, you have four realistic options — in order of preference:
- Call the funder and request an ACH modification. If your revenue has dropped since you signed, some funders will extend your term and reduce the daily amount. Not all will, but it costs nothing to ask.
- Increase revenue. Not easy, obviously. But if the advance funded inventory or marketing that's starting to pay off, focus on converting that investment to cash flow before considering any other action.
- Refinance — carefully. If your credit and revenue have improved since the original deal, you might be able to refinance into a lower-factor advance. Do not do this if it involves taking more capital — refinancing into a larger advance that "payoffs off" the old one plus gives you extra cash is almost always a worse deal.
- Do not take a second MCA. Stacking is how this ends badly. If you're over the threshold on advance #1, advance #2 will accelerate the problem, not solve it.
If none of those options are available and the advance is genuinely threatening the business, consult a business attorney about restructuring options before the funder files on the UCC lien.
Frequently asked questions
- Can I renegotiate my daily ACH amount after signing?
- Some funders allow ACH adjustments if your revenue drops significantly. Credibly and OnDeck both have reconciliation processes — you submit recent bank statements showing a revenue drop, and they'll reduce the daily withdrawal accordingly, extending the term. Not all funders offer this. Read your contract for 'reconciliation' or 'adjustment' clauses before signing — that's the time to know, not after.
- What happens if I miss an ACH payment?
- It depends on the funder. Most send a retry the following business day. Two or three consecutive failures will trigger a default notice and potentially lock your account. Some contracts allow the funder to debit a larger amount to catch up missed payments. The key danger: a missed ACH often means an NSF on your bank statement, which damages future fundability.
- Will the funder seize my bank account if I default?
- Funders can't literally freeze your account — they don't have that power. What they can do: continue ACH retry attempts (which cause NSFs), file on the UCC lien (which can cloud your business credit), and in some states, pursue a confession-of-judgment that allows collections without a full court proceeding. The more aggressive collections tactics are a slow process — but they're real.
- Can I move banks to avoid ACH?
- You can open a new account, but the funder has your original account information and UCC lien on file. Deliberately moving accounts to avoid a legitimate ACH obligation is considered fraud in most jurisdictions and can accelerate collections action. If your ACH is unmanageable, the right move is to call the funder and request an ACH modification — not to disappear.
- Is weekly ACH always better than daily ACH?
- Not always. Weekly ACH means a larger single debit (5× the daily amount), which can be harder to absorb on a lean week. For businesses with very consistent revenue (subscription-based, recurring clients), daily ACH is actually smoother. For businesses with lumpy or seasonal revenue — restaurants, event services, retail — weekly ACH can help because you accumulate more cash before the withdrawal hits.
