Daily ACH business loan payments are calculated by taking the total repayment amount and dividing it by the number of business days in the loan term. For a merchant cash advance, that means multiplying the advance amount by the factor rate to get the total payback, then dividing by the number of business days to set the daily withdrawal.
For a short-term business loan, the math uses the loan amount, the interest charges, and any fees, then spreads the total across business days. The structure itself is simple. The cost details, and how a business should plan around them, are where the differences show up.
What a Daily ACH Payment Actually Is in Business Lending
A daily ACH payment is a fixed dollar amount that an alternative lender withdraws directly from your business bank account each business day until the financing is paid off. ACH stands for Automated Clearing House, the U.S. electronic payment network that handles direct bank-to-bank transfers. The lender sets up a recurring debit that runs Monday through Friday, skipping weekends and federal holidays.
Daily ACH is common in two products: merchant cash advances and short-term business loans from alternative lenders. Traditional bank loans almost always use monthly payments. The daily structure exists because alternative lenders are funding higher-risk borrowers and want to collect frequently to reduce the chance of default. It also tracks revenue patterns more closely than a once-a-month payment.

How Daily Payments Are Calculated for a Merchant Cash Advance
For an MCA, the formula is straightforward. The provider buys a fixed dollar amount of your future revenue. That amount is your advance multiplied by the factor rate, and the daily ACH is that total divided by the number of business days in the term.
Imagine a business is approved for a $50,000 advance with a factor rate of 1.30 over a 10-month term. The total payback is $50,000 multiplied by 1.30, or $65,000. Ten months is roughly 220 business days (about 22 business days per month). The daily ACH would be $65,000 divided by 220, which is $295.45 per business day.
The fixed daily amount is typically set based on a percentage of historical monthly revenue, often 8 to 15 percent of average monthly deposits. If actual revenue drops materially after funding, reconciliation provisions can adjust the daily amount, but the total payback stays the same.
How Daily Payments Are Calculated for a Short-Term Business Loan
For a short-term loan, the math accounts for interest and any origination fees. The lender calculates the total cost of the loan upfront and divides by the term in business days.
Imagine the same business borrows $50,000 as a short-term loan at 24 percent simple interest over a 12-month term. The total interest is $50,000 multiplied by 0.24, or $12,000. Add a 3 percent origination fee of $1,500, and the total payback is $63,500. With roughly 260 business days in 12 months, the daily ACH would be $63,500 divided by 260, or $244.23 per business day.
The exact calculation varies by lender. Some compound interest, others use simple interest, and some quote interest as a fixed fee rather than an APR. Always ask the lender for the total payback amount and the daily payment in writing before signing.

Business Days vs Calendar Days
This trips up some borrowers. Daily ACH is calculated against business days, not calendar days. A 12-month term doesn’t mean 365 daily payments. It means roughly 252 to 260 business days, depending on the calendar year and federal holiday schedule.
That’s why the daily payment looks higher than you might expect when you do a rough mental calculation. If you took $63,500 and divided by 365 calendar days, you’d get $173.97. The actual ACH at $244.23 is higher because you’re only paying on weekdays.
The structure works in your favor in a subtle way. Holidays and weekends give your bank account room to recover before the next withdrawal hits. Some businesses with strong weekend revenue, like restaurants and retail shops, find this rhythm fits their cash flow better than a single large monthly payment.

What Daily ACH Does to Cash Flow
A consistent daily withdrawal can ease month-end pressure compared to a lump sum. It also takes discipline. According to Shopify’s analysis of common cash flow problems facing small businesses, late customer payments and seasonal fluctuations are two of the most frequent reasons businesses run short on cash. When daily ACH lines up with a slow revenue period, the math can squeeze cash flow even when total monthly revenue looks normal.
Some practical tips: track your average daily deposits and compare them to the daily ACH amount. If the ACH represents more than 10 to 12 percent of your daily revenue, the cushion is thin. Build a buffer in your business checking account, and consider products with reconciliation provisions if your revenue is variable.

Frequently Asked Questions
How many business days are in a typical 6-month MCA term?
A 6-month term works out to roughly 130 business days, depending on the calendar year and number of federal holidays. Lenders typically round to a standard number (often 130 or 132 days) when calculating the daily ACH at funding.
Can the daily ACH amount change after funding?
For MCAs, the answer is yes if the contract includes reconciliation provisions and your revenue has dropped meaningfully. For most short-term loans, the daily ACH is fixed for the life of the loan unless you refinance or restructure.
Do daily ACH payments include weekends?
No. Daily ACH typically runs Monday through Friday only, skipping weekends and federal holidays. The withdrawal posts when banks process business-day transactions.
What happens if my account doesn’t have enough money to cover a daily ACH payment?
You’ll likely incur an NSF fee from your bank and a returned-payment fee from the lender. Repeated failed payments can trigger default provisions in the contract. If you anticipate a shortfall, contact the lender before the payment runs.
Is the daily ACH the same as my factor rate?
No. The factor rate is a multiplier (like 1.30) that determines your total payback. The daily ACH is the dollar amount withdrawn each business day to repay that total over the term.
Can I pay off a daily ACH advance early?
For MCAs, early payoff is usually possible but doesn’t reduce the total amount owed. The factor rate is fixed regardless of how quickly you repay. Some short-term loans charge prepayment penalties, while others let you save on interest by paying early. Check your specific agreement.
