THE DISCOUNT AS A YEARLY RATE

Reading the terms

“2/10 net 30” means: take 2% off if you pay within 10 days; otherwise pay the full amount within 30. The choice is between paying 98 on day 10 and paying 100 on day 30. Waiting costs you 2 to keep 98 for 20 more days.

yearly rate = discount ÷ (100 − discount) × 365 ÷ (net days − discount days)

For 2/10 net 30 that is 2 ÷ 98 × 365 ÷ 20 = 37.2% a year. Compounded, because you could do it again every twenty days, it is higher still.

If a supplier offers it

Compare that rate with what money costs you. If you can borrow at 9% and the discount is worth 37%, take the discount, even if you borrow to do it. The exception is when cash is genuinely short: a discount you cannot fund is not a bargain.

If you are thinking of offering it

The same sum runs against you. You are paying your customer a high yearly rate to have your money a little sooner. That can still be right: if late payment is hurting you, or your own borrowing is expensive, faster cash has a price worth paying. Offer it knowing the price, and watch for customers who take the discount and still pay late.

Questions

Why is the rate so high?

Because the period is so short. A small percentage earned over twenty days repeats eighteen times in a year.

Simple or compounded: which should I use?

Simple is the usual quoted figure and is fine for a decision. Compounded is the true comparison with a rate that is itself compounded, such as most loans.

What if I pay on day 45 anyway?

Then the gap is 35 days, not 20, and the rate falls. Enter the day you really pay. Paying late has costs this sum does not see: the supplier’s goodwill, and your place in the queue when stock is short.

Is my data sent anywhere?
