Abstract

A method and a system are provided wherein an interest rate fluctuates according to the ratio of a borrower'"'"'s funds on deposit with the lender, to the borrower'"'"'s outstanding indebtedness (or to the outstanding indebtedness combined with line of credit) at any time, and for the duration of a selected period of time. The ratio of the borrower'"'"'s funds on deposit with the lender, to the borrower'"'"'s loan balance (or to the borrower'"'"'s loan balance combined with line of credit), forms a Compensating Balance.

This method and system provide for each individual lender to set a "par point", which is the Compensating Balance required by the lender in order for the borrower to qualify for a pre-determined interest rate. The interest rate of the loan automatically fluctuates inversely to the fluctuation of the borrower'"'"'s Compensating Balance from the "par point". As the Compensating Balance increases, the interest rate decreases, and as the Compensating Balance decreases, the interest rate increases.

Claims

1. A method for providing data regarding interest rates comprising the steps of:

storing the value of a borrower'"'"'s funds on deposit in a computer memory;

storing the amount of a borrower'"'"'s indebtedness in the computer memory;

monitoring the computer memory periodically by a scanning means connected to the computer memory to determine the extent of the borrower'"'"'s indebtedness and the value of the borrower'"'"'s funds on deposit at a given time, the scanning means providing at its output a signal corresponding to the borrower'"'"'s indebtedness and funds on deposit;

comparing the borrower'"'"'s funds on deposit to the borrower'"'"'s indebtedness by a division circuit means which is connected to the scanning means to determine the ratio of output of the scanning means to form a Compensating Balance; and

increasing the interest rate provided by a printout connected to the division circuit means, if the Compensating Balance is less than par point and decreasing the interest rate provided by the printout if the Compensating Balance is greater than par point.

2. The method of claim 1, further including the steps of:

determining and storing in the computer memory a par point for initial Compensating Balance and setting an interest rate for that par point; and

comparing by a first comparator means subsequently determining Compensating Balance to the initial Compensating Balance to determine whether to increase or decrease the interest rate.

3. The method of claim 2 further including steps of:

storing a table of values in the computer memory, wherein a series of Compensating Balances are matched to corresponding interest rates; and

comparing by a second comparator means the determined Compensating Balance to the table, in order to determine the interest rate provided by the printout.

4. A system for computing interest comprising:

first memory means for storing the value of a borrower'"'"'s funds on deposit and providing at an output a first signal which corresponds to the funds on deposit;

second memory means for storing the amount of a borrower'"'"'s indebtedness and providing at an output a second signal which corresponds to the indebtedness;

third memory means for storing the amount of a borrower'"'"'s line of credit and providing at an output a third signal which corresponds to the line of credit;

means for scanning said first, second and third signals periodically, said means for scanning connected to the outputs of said first, second and third memory means and providing at an output a fourth signal corresponding to the extent of the borrower'"'"'s loan balance and line of credit and the value of the borrower'"'"'s funds on deposit at a given time;

means for comparing the borrower'"'"'s funds on deposit to the borrower'"'"'s loan balance and line of credit, said means for comparing connected to the output of said means for scanning providing at an output a fifth signal corresponding to a Compensating Balance; and

means for determining connected to the output of said means for comparing providing at an output a sixth signal corresponding the interest rate based on the Compensating Balance.

5. The system of claim 4 wherein:

said first memory means is comprised of a first memory having an input for receiving deposits and an output for providing withdrawals;

said second memory means is comprised of a second memory having an input for receiving money paid to an account and an output for providing money loaned from an account;

said means for scanning is comprised of a first periodic monitor connected to said first memory and a second periodic monitor connected to said second memory;

said means for comparing is comprised of a division circuit; and

said means for determining is comprised of a par point memory connected to a periodic scanner connected to a par point comparator, and interest rate schedule memory connected to a periodic scanner connected to an interest rate comparator connected to a card printout, said par point comparator connected to said division circuit and said interest rate comparator.

6. An apparatus for providing data regarding a borrower'"'"'s interest rates computed from a value of a borrower'"'"'s funds on deposit, a value of the borrower'"'"'s indebtedness and a value of the borrower'"'"'s interest rate at a par point comprising:

first memory means having an input and an output, said input for receiving information regarding transactions relating to the borrower'"'"'s funds on deposit and the borrower'"'"'s indebtedness said output providing a signal corresponding to the borrower'"'"'s funds on deposit and the borrower'"'"'s indebtedness;

first comparator means having an input and an output, the input of said comparator means connected to the output of said memory means, and the output of said comparator means providing a signal corresponding to a Compensating Balance which is a ratio of the borrower'"'"'s funds on deposit to the borrower'"'"'s indebtedness;

second memory means having an input for receiving information regarding an interest rate and par point schedule and having an output providing a signal which corresponds to the interest rate and par point schedule;

second comparator means for comparing the output of said second memory to the output of said first comparator means, said second comparator means having an output providing a signal which corresponds to the indebtedness, funds on deposit, par point, Compensating Balance and interest rate; and

print means having an input for receiving the output of said second comparator, said print means providing a card having information corresponding to the output signal of said second comparator.

7. The apparatus of claim 6 wherein said first memory means further comprises a periodic monitor and said second memory means further comprises a periodic scanner.

8. The apparatus of claim 7 wherein said first comparator is a division circuit.

9. The apparatus of claim 8 wherein said first memory means has inputs for receiving money paid to an account and for receiving deposits and has outputs for providing money loaned from accounts and for providing withdrawals.

10. The apparatus of claim 9 wherein said print means is a send and receive printer.
