Net terms & early payment

Net-60 is a loan you make the client at 0% interest. An early-payment discount is you buying your own money back. Both have exact prices; this computes them so the decision stops being a vibe.

Your numbers
$

The invoice under negotiation.

30, 45, 60, 90: whatever the contract says.

%

What idle money costs you per year: savings yield if you are liquid, your credit line's APR if you are not.

%

The classic is 2% (as in "2/10 net 30"). Zero if none is offered.

Days within which the discounted payment must arrive.

The discount beats your opportunity rate: worth taking or offering.

Estimate, not advice

The formula

Waiting cost = amount × your rate × days ÷ 365. Implied rate of a discount = (d ÷ (1 − d)) × (365 ÷ days gained). The classic 2/10 net 30 works out to about 37% annualized, which is why buyers love it.

What this ignores

Default risk (money now is also money CERTAIN), the relationship cost of pushing terms, and cash-crunch situations where liquidity beats any rate math. When you need the cash to make rent, the implied rate is academic.

Field notes

Should I offer early-payment discounts to clients?
Only if slow payment is actually hurting you, and at 1-2% maximum with a tight window. At 37% annualized, 2/10 is expensive money; often a deposit requirement or shorter net terms achieves the same cash flow for free.
A big client demands net-60. What do I do with this number?
Price it in. The waiting cost this tool computes belongs in your rate for that client, stated or not. Net-60 at a 3% higher price is the same deal for you and usually invisible to procurement.
A client offers to pay early IF I discount. Take it?
Compare the implied annual rate against your opportunity rate, which this tool does. Liquid and earning 4% in savings? A 37%-implied discount is a terrible sell. Financing the gap on a 25% APR card? Take the deal.
