CONVERSATION IX.

DISCOUNT AND EQUATION OF PAYMENTS.

Tut. What is discount?

Pup. Discount, I believe, is an allowance made for the payment of a debt before it becomes due.

1. Tut. Discount is an allowance made by the creditor to the debtor, for the payment of a debt before it becomes due, and is the difference between that sum, due sometime hence, and its present worth. If A. owe B:

$500, payable in 6 months, with interest, after it becomes due, he would, by paying the debt before the 6 months were out, confer a favour on B. for which B. ought to make an allowance, and this allowance is the discount.

2. By the present worth, is meant such a sum, which, put at interest, would in the given time, and at the given rate, amount to the debt then due.

3. It is very evident that an allowance ought to be made for paying a debt before it is due; for if the debtor keep the money in his own hands, he can employ it to his own benefit, while it is of no benefit to the creditor; but if he pay the debt before it is due, he relinquishes this privilege to the creditor, hence the reason of making a discount.

4. Now the present worth is such a sum, which if put to interest, would, in the given time, and at the rate per cent. for which the discount is to be made, amount to the sum or debt then due. At first you might suppose the discount to be the interest on the sum or debt, from the time at which it is paid, to the time at which it is due. But this is not true, for if you cast the interest on the whole debt from the time it is paid to the time when it would become due, and subtract this interest from the whole debt, the remainder, put at interest for the same time and rate, will not amount to the debt, therefore the discount is not so much as the interest on the sum, for the time and rate for which the discount is to be made, but the discount is such a sum, which will be equal to the interest on the present worth for the given time and rate.

Hence the following rule for

[ocr errors]

DISCOUNT.

As the amount of $100 for the given rate and time is to the given sum or debt, so is $100 to the present worth.

or, As the amount of $100 for the given rate and time is to the give en sum or debt, so is the interest of $100, for the same time, to the discount,
