Early Payment Discounts Hand Buyers a 37 Percent Return

A 2/10 net 30 early payment discount costs the seller about 37.2% a year, a yearly rate that hands the return to the buyer with cash on hand. Two percent off an invoice looks small. Once you price the 20 days of speed you are buying, it is a short loan from your margin to their treasury.

Large payables desks now run that loan as a product. The late customers who actually strain cash almost never claim it, which is why the offer so often pays the wrong party.

A 2 Percent Cut Costs 37.2 Percent a Year

2/10 net 30 means the buyer may take 2% off if the bill is paid within 10 days; otherwise the full amount is due in 30. On a $10,000 invoice that is $200, and the buyer pays $9,800. You gave up $200 to pull cash forward 20 days.

The yearly cost is [discount ÷ (100 – discount)] × [365 ÷ (full term – discount period)]. For 2/10 net 30 that is (2 ÷ 98) × (365 ÷ 20), or 0.0204 × 18.25, which comes to 37.2%. You are paying a 37.2% yearly rate for three weeks of faster cash.

YEARLY COST OF COMMON CASH DISCOUNTS

A 1% window still prices above most bank loans. A 3% window jumps to 56.4%. Stretching the net date to 60 days with the same 2% cut drops the yearly cost to 14.9%, because you are only buying 50 days of float you had already planned to give.

The 2% comes straight off gross, so a thin-margin shop feels it first. A firm running 15% margins is not giving away spare change. It is giving away a slice of the profit on every invoice the buyer chooses to prepay.

Corporate Treasuries Treat Payables as a Yield Product

On the other side of the invoice, 37.2% is a return. Any treasurer whose cash earns a low single-digit yield will take that cut whenever the approval cycle can hit day 10. SAP Taulia sells software to turn payables into a profit center, pitching a no-risk stream from early-pay discounts the buyer funds with idle cash.

We saw at least a 2.5x ROI over and above making investment decisions on our cash, borrowing in the market, including spending money on the program itself.

Google’s supplier help pages walk vendors through the same trade in plain language: under a standard 2/10 net 30 term, the supplier gives Google a 2% discount to be paid 20 days early. Dynamic programs then replace the cliff with a sliding scale, so a buyer who misses day 10 still earns a prorated cut instead of zero.

Paul Kizirian, executive director for treasury consulting at J.P. Morgan, told commercial clients that if the buyer can capture discounts on a steady basis, the savings show up on the bottom line. He also said terms follow trade leverage. Scale, and whether the goods are a commodity or a must-have, decides who sets the clock.

That is the split. The buyer with cash, software, and leverage treats 2/10 as yield. The seller who printed it to “get paid faster” is the one supplying the yield.

Why Chronic Late Payers Ignore the Discount

The customers who hurt cash flow are not the ones racing to day 10. They are the ones still open at day 40. Atradius’s U.S. Payment Practices Barometer for 2025 put 52% of the value of credit-based B2B invoices as paid on time, 43% overdue, and 5% written off, with average stated terms of 45 days and about 50% of U.S. B2B sales made on credit.

WHO TAKES THE CUT, WHO WAITS

• On-time share: Atradius found 52% of U.S. credit-based B2B invoice value paid on time in 2025, with 43% overdue.
• Discount window: J.P. Morgan, citing APQC, says the median organization pays 96% of invoices on time yet pays only 15 percent of invoices inside a discount period.
• When a discount exists: APQC’s measure 101947, drawn from 2,076 companies, puts the median capture of discounts that were actually offered at 65.0%.
• Stated terms: Average U.S. B2B credit terms in that Atradius survey sat at 45 days, already past a classic net-30 due date.

Those two APQC figures are not a conflict. Fifteen percent of all invoices land in a discount window because most bills never offered one. Of the bills that do, the median shop still takes 65 percent of available discounts. The remaining third is the slow approval pile, not the distressed account.

Kizirian’s point on liquidity sits underneath that pattern. Buyers short on cash seek longer net terms and skip the window so they can hold the money. Buyers with cash automate the capture. Offer 2/10 to a mixed book and you subsidize the second group while the first group keeps paying late.

Washington Already Runs the Same Math

Federal agencies have been told to harvest a cheap discount for decades. Congress passed the Prompt Payment Act in 1982 to make agencies pay on time, pay interest when they are late, and take discounts when the numbers work. The Prompt Payment interest rate for July 1 through December 31, 2026 is 4.75%.

The Bureau of the Fiscal Service puts the test on the government’s own discount calculator. If the effective yearly discount rate is larger than the current value of funds rate, take the discount and pay early. If it is smaller, wait until the due date. The calculator’s value-of-funds box is filled at 4.00%.

A 37.2% offer clears 4.00% by a wide gap, more than nine times that hurdle. Agencies are not being generous when they pay on day 10. They are following a rule that says the vendor underpriced the float.

The Civil War Shortcut That Stuck

Cash discounts are older than the software now used to sweep them. After the Civil War, greenback prices jumped around against gold, and a four-to-six-month open account could leave a seller holding money that had lost value. Eastern wholesalers shortened terms toward 30 days and sweetened the new clock with a discount for paying even faster. The shorter terms stayed after convertibility returned in 1879.

HOW THE 2/10 WINDOW HARDENED

1. 1860s-1870s: Wholesalers cut long open-account terms toward 30 days and add a cash discount so buyers settle before the money loses value.
2. 1879: Greenbacks become exchangeable for gold again, but the shorter terms and the early-pay cut remain standard practice.
3. 1916: Commercial-credit manuals already price 2/10 net 30 at 37.2% a year for the buyer who skips the window, the same arithmetic still used on invoices.
4. 1982: The Prompt Payment Act tells federal agencies to take an economically sound discount, locking the harvest into public-sector payables.
5. 2010s-2020s: Dynamic discounting platforms replace the day-10 cliff with a sliding scale so a late approval still earns the buyer a prorated cut.

The formula did not sneak up on anyone. Credit clerks could compute it with a pencil. What changed is who can hit the window on every invoice, every cycle, without a clerk watching the calendar.

Borrowing at Prime Beats Giving Away 2 Percent

Compare 37.2% with what cash actually costs. The Wall Street Journal prime rate in September 2026 is 6.75%. The Federal Reserve Bank of Kansas City’s Small Business Lending Survey for the first quarter of 2026 put urban-bank rates on new small-business credit at 6.7% fixed and 7.1% variable. Even the tightest SBA maximums on 7(a) loans sit far below the discount: variable caps run from prime plus 3.0% on loans above $350,000 (9.75%) to prime plus 6.5% on loans of $50,000 or less (13.25%).

WHAT CASH COSTS NEXT TO A 2/10 CUT

The discount is more than five times prime. Take a firm that bills $80,000 a month on net-30 terms, with clients often paying around day 40. If every client took 2/10, the shop would give up about $1,600 a month, or $19,200 a year, to get paid roughly 30 days sooner. A 30-day draw of $80,000 at the 7.1% urban variable rate costs about $467. The line of credit buys the same speed for a few hundred dollars. The discount buys it for $1,600, every cycle, off a book that may only earn 15% margins.

The transfer is still rational in a narrow set of cases: payroll is at risk and no cheaper facility exists, margins can absorb 1%-2% without pain, or the cash can be put back to work at a return above 37.2%. Those cases are real. They are also the exception, not the default printed on a template invoice.

Sellers Can Buy Speed Without Cutting Prices

Most of the acceleration a 2% window is meant to buy can be had without handing the cash-rich buyer a 37.2% loan. Clients often pay on the date you set, so the first lever is the date.

SPEED THAT LEAVES THE INVOICE WHOLE

• Shorter terms: Move the due date from net 30 to net 15 and many accounts will simply pay on the new date.
• Deposits: Take a portion up front on larger jobs so you are not financing the whole project on your own cash.
• Same-day invoices: Bill when the work ships or the milestone hits, not in a month-end batch that already burned a week.
• One-click pay: Put a payment link on the invoice; extra steps are a common reason a willing buyer slips past day 10.
• Reminder cadence: Automate pings before and after the due date so collections time is not the hidden cost of net 30.
• A stated late fee: Price the delay onto the slow account instead of paying the fast one to do what it could already do.

Those steps cost margin nothing. They also aim the pressure at the accounts that actually pay late, which is the group a 2/10 window almost never moves. Keep a selective early-pay deal for a slow-but-strategic customer you want to nudge without a fight, and only after you have priced it against a real facility, not against a fear of empty checking.

Frequently Asked Questions

When Does the 10-Day Discount Clock Start?

Under the Prompt Payment rule used by federal agencies, the discount period starts on the invoice date if the invoice is proper and dated. If there is no invoice date, it starts when the agency received the invoice. Private contracts can set a different trigger, which is why a buyer who still gets paper bills in the mail can miss day 10 even when the intent was to take the cut.

What If the Buyer Pays on Day 11?

Classic 2/10 net 30 is a cliff. Day 11 pays the full amount, with no residual credit for missing the window by a day. Sliding-scale dynamic discounting is the product built to stop that miss, and it is the version large buyers now install so a late approval still earns a prorated cut after day 10.

How Is a Late Fee Different From a 2/10 Discount?

They point in opposite directions. The discount pays the buyer who already has cash to move early. A late fee charges the account that blew the due date. If chronic lateness is the problem, a fee (or a shorter net date) prices the delay onto the party that caused it and leaves the 2% on your invoice.

Should Every Customer Get the Same Early-Pay Terms?

No. Terms are a contract point, and Kizirian’s leverage rule applies. You can hold net 15 as the default, require deposits on large jobs, and reserve a priced early-pay window for a named account you have already compared with a line of credit. Printing 2/10 on every invoice is how the cash-rich book collects a 37.2% return you did not mean to fund.

The Fiscal Service calculator still carries a 4.00% value-of-funds rate. Any 2/10 net 30 offer clears that hurdle, which is why the buyer with cash and a fast desk will keep taking the cut for as long as sellers keep printing it on the bill.
