The idea
When a business needs cash before a cheque or promissory note is due, a bank or buyer may pay for it now at a discount. The discount is the cost of receiving the money early.
The simple discount formula
discount = face value × annual discount rate × (months ÷ 12)
amount paid now = face value − discount
Worked example
A cheque for 100,000,000 Toman, due in 3 months, discounted at 24% a year (an example rate):
- Discount: 100,000,000 × 0.24 × 3 ÷ 12 = 6,000,000 Toman
- Paid now: 94,000,000 Toman
Watch for
- Risk: if the cheque bounces, the person who discounted it may have to repay.
- Fees: banks may add fees on top of the discount.
- The real rate: because you receive less than the face value, the effective interest rate is slightly higher than the quoted discount rate.
Tools for this
Examples use illustrative rates. Check the terms and your legal obligations before discounting a cheque.
