An early payment discount is a price reduction you offer a customer who pays before the due date. The best-known form is 2/10 net 30: take 2% off if the invoice is paid within 10 days, otherwise the full amount is due within 30 days. It can bring cash in faster, but the discount is often far more expensive than it looks, so it deserves a calculation before you put it on your invoices.
How does 2/10 net 30 work?
Take a 10,000 invoice. A customer who pays by day 10 sends 9,800. A customer who does not pays the full 10,000 by day 30. In practice you give up 200 in exchange for receiving your money 20 days earlier than the normal due date.
That 200 looks small next to 10,000, but it buys only 20 days of cash. The shorter the period you accelerate, the more expensive each percentage point becomes when measured over a year.
How to calculate the effective annual cost
Compare what the discount costs you with the time it saves, then scale that to a full year so you can compare it with other sources of cash.
- Cost for the period: discount ÷ (100% − discount) = 2 ÷ 98 = about 2.04%.
- Days accelerated: net days − discount days = 30 − 10 = 20 days.
- Periods per year: 365 ÷ 20 = 18.25.
- Simple annual rate: 2.04% × 18.25 = about 37.2%.
- Compounded annual rate: (1 + 0.0204)18.25 − 1 = about 44.6%.
So 2/10 net 30 is equivalent to paying roughly 37% to 45% a year for the cash you receive early. Other terms look very different: 1/10 net 30 works out to about 18% simple, and 2/10 net 60 to about 15%, because the longer the gap you close, the cheaper the discount is per year.
When does an early payment discount make sense?
The test is simple: the discount is worth offering only if its effective annual cost is lower than the cost of the next best way to get the same cash.
- Your alternative financing is expensive: if you rely on an overdraft, a short-term loan, or invoice factoring that costs more than the effective rate, the discount is the cheaper option.
- Cash is genuinely tight: when a gap in cash would delay payroll, supplier payments, or growth, speed can be worth a premium.
- Customers already pay very late: if your real average is 60 or 75 days, a discount that pulls payment to 10 days closes a large gap.
- Your margin can absorb it: the discount comes straight out of profit, so it suits businesses with healthy gross margins.
- You want less credit risk: money received sooner is money that cannot become a bad debt.
If you can borrow at 10% a year, giving a 37% equivalent discount to collect 20 days early is a poor trade. If you have no cheap credit and your margin is high, it may be a sensible one.
Pitfalls to avoid
- Customers take it and pay late anyway: some will deduct the discount while paying on day 25 or day 40. Decide in advance how you will handle it, and be consistent.
- You discount customers who would have paid on time: your most reliable payers get a price cut for behaviour they already had.
- Margin erosion: a 2% discount on a 10% margin gives away a fifth of your profit on every invoice that qualifies.
- Messy reconciliation: short payments, partial deductions, and unclear cut-off dates create work for your finance team.
- Tax effects: a discount can change the taxable amount for VAT or sales tax. Check how it applies where you operate, and with your accountant, before you rely on it.
- Unclear terms: if the discount and its cut-off are not printed on the invoice, disputes follow.
- Treating it as a fix for chronic late payers: a discount rewards good habits; it does not replace reminders and follow-up.
How to introduce one sensibly
- Calculate first: set the discount below the cost of your cheapest alternative financing.
- Start small: offer it to a handful of customers, or only on large invoices, and measure the result.
- State it clearly: print the percentage, the number of days, and the rule that payment must be received by the cut-off date.
- Enforce the deadline: a discount that is honoured after the deadline soon stops motivating anyone.
- Track the take-up: measure how many customers use it and how much your average collection time really falls.
Whatever you decide, a discount only works if you can see who pays when. FulcrumGrid Collection tracks invoices, due dates, and reminders in one place, so you can send a nudge before a discount window closes and see which customers are paying late. It will not tell you whether a discount is worth the margin, but it gives you the payment data to judge that for yourself.
Frequently asked questions
What does 2/10 net 30 mean?
It means the customer may deduct 2% from the invoice if they pay within 10 days; otherwise the full amount is due within 30 days.
How do I calculate the annual cost of an early payment discount?
Divide the discount by 100% minus the discount to get the cost for the period (2 / 98 = 2.04%), then multiply by 365 divided by the days you accelerate payment (20 days gives 18.25). The simple result for 2/10 net 30 is about 37%, or roughly 45% when compounded.
Is a 2% early payment discount worth it?
Only if the effective annual cost, around 37% for 2/10 net 30, is lower than the cost of other financing available to you and your margin can absorb it. If you can borrow cheaply, it usually is not worth it.
What if a customer takes the discount but pays late?
Set a clear rule on the invoice that the discount applies only if payment is received by the cut-off date. If a customer deducts it anyway, ask for the balance and apply the rule consistently so others do not copy the habit.
