DISCOUNT.

DISCOUNT is an allowance made for the payment of any sum of money before it becomes due; and is the difference between that sum due some time hence, and its present worth.

The

The present worth of any sum, or debt, due some time hence is such a sum, as, if put to interest, would in that time and at the rate per cent. for which the discount is to be made, amount to the sum or debt then due.

RULE.*

1. As the amount of tool. for the given rate and time is to rool. so is the given sum or debt to the present worth.

2. Subtract the present worth from the given sum, and the remainder is the discount required.

Or,

As the amount of 100l. for the given rate and time is to the interest of 100l. for that time, so is the given sum or debt to the discount required.

EXAMPLES.

* That an allowance ought to be made for paying money before it becomes due, which is supposed to bear no interest till after it is due, is very reasonable; for, if I keep the money in my own hands till the debt becomes due, it is plain I may make an advantage of it by putting it out to interest for that time; but if I pay it before it is due, it is giving that benefit to another; therefore we have only to enquire what discount ought to be allowed. And here some debtors will be ready to say, that since by not paying the money till it becomes due, they may employ it at interest, therefore by paying it before due, they shall lose that interest, and for that reason all such interest ought to be discounted: but that is false, for they cannot be said to lose that interest till the time the debt becomes due arrives; whereas we are to consider what would properly be lost at present, by paying the debt before it becomes due; and this can, in point of equity or justice,
