A discounted loan deducts interest or another finance charge in advance, so the borrower receives less than the obligation's face amount.
A discounted loan, or discount-interest loan, deducts interest or another finance charge in advance. The borrower receives net proceeds below the obligation’s face amount but remains responsible for the face amount according to the repayment terms.
The quoted discount rate is applied to the face amount, not the smaller amount the borrower actually receives. As a result, the borrowing cost measured against usable proceeds is higher than the stated discount rate.
For a simple single-payment discount loan, the advance discount can be represented as:
Where:
If fees are also deducted, the borrower’s usable proceeds or regulatory amount financed can be lower still. The disclosed APR is determined under applicable rules and should not be inferred from the discount rate alone.
Assume a one-year note has:
Discount interest is:
Net proceeds are:
The borrower receives $9,400 and owes $10,000 at maturity. Measured against the funds received, the simple one-year cost is:
If an additional $50 prepaid finance charge were withheld, usable proceeds would fall to $9,350. The regulatory APR calculation would reflect required timing and finance-charge rules; it would not simply equal 6.383%.
With ordinary simple interest, interest is commonly calculated on the principal advanced to the borrower. With discount interest, the charge is calculated on the larger face amount and withheld before disbursement.
| Structure | Cash received | Amount on which quoted charge is based | Amount due under simple one-year example |
|---|---|---|---|
| 6% simple-interest loan | $10,000 | $10,000 | $10,600 |
| 6% discount-interest note | $9,400 | $10,000 face amount | $10,000 |
Both examples show a $600 stated charge, but the discount loan supplies only $9,400 of cash. Comparing the quoted percentages without examining proceeds therefore understates the relative cost of the discount structure.
The word discount has several finance meanings:
| Term | Meaning | Same as discount interest? |
|---|---|---|
| Discount-interest loan | Interest is withheld from proceeds in advance | Yes |
| Debt trading below par | An existing instrument’s market price is below face value | No |
| Original issue discount | A debt instrument is issued below stated redemption price under applicable terms | Related valuation concept, but not automatically a discount-interest consumer loan |
| Mortgage discount points | Upfront charge associated with obtaining a stated mortgage rate | No |
| Invoice discount | Reduction offered for early trade payment | No |
| Present-value discounting | Future cash flow is converted to current value | No |
A zero-coupon bond issued below par should not automatically be called a discounted loan. Its investor pricing, tax treatment, and market valuation are separate issues from a creditor withholding discount interest from loan proceeds.
Add-on and discount methods can use the same nominal rate and produce the same dollar finance charge, yet structure the obligation differently.
Using a $1,000 one-year loan and 6% precomputed charge:
The Consumer Financial Protection Bureau’s official interpretation of Regulation Z uses these structures to illustrate how finance charges and amount financed are disclosed.
For a covered U.S. consumer transaction, Truth in Lending disclosures may include:
The amount financed is not always the check or deposit the borrower sees, because fees paid to third parties or other amounts can affect the itemization. The face amount is also not necessarily the amount financed.
APR converts the cost and payment timing into a standardized annual measure. It is generally more useful than the discount rate for comparing borrowing structures, but only when the underlying loan amount, term, payment schedule, and included charges are also understood.
The simple formulas above assume one payment at maturity. An installment discount loan can involve periodic payments even though the finance charge was determined or withheld at origination. In that case, effective cost depends on when principal is returned, not only on the total charge.
Review the actual schedule rather than applying the single-payment formula to an amortizing loan. A stated discount rate does not by itself reveal the payment-level internal rate of return.
If a borrower prepays before scheduled maturity, the contract and applicable law determine whether part of the precomputed or discounted charge is rebated as unearned interest. Possible allocation methods can produce different refunds.
Ask for a dated payoff statement showing:
It is inaccurate to assume either that all withheld interest is retained or that it is all refunded.
Before comparing it with another loan, identify:
For short-term credit, small differences between face amount and proceeds can create a much higher annualized cost than the quoted discount rate suggests.
