# CALC 1 Time Value of Money Example For TVM Calculator

These examples are for the "Financial: TVM" calculator with periodic interest rate ("i%" key instead of "I/YR" key).

Key Description Calculates, stores or recalls the number of periods. Calculates, stores or recalls the periodic interest rate as a percentage. Calculates, stores or recalls the present value. Calculates, stores or recalls the periodic payment. Calculates, stores or recalls the future value.  Multiplies the value in the x register and stores it as the number of periods.  Divides the value in the x register and stores it as the number of periods.  Calculates the interest and principal for the number of periods in the x register.  Calculate simple interest.

## Time value of money example:

What are the monthly payments for a 100,000 loan for 20 years at 6% per year?  to clear the financial variables,

240 Stores the number of payments (20 * 12),

This can also be entered as 20  0.5 Stores the periodic (6% / 12 payments per year) interest rate,

This can also be entered as 6  100000 Stores the present value Calculate the payment

The result is -716.43.

By default the financial BEGIN END mode is set to END. ## Amortization example:

We recommend using the Amortization Form Calculator.

What is the interest and principal for the first 12 payments for the loan above?

Set the starting payment period to 0:

0 Calculate the interest and principal for the first 12 payments:

12  The principal paid of -2,669.79 is displayed in the y register (if you have two or more rows displayed)
The interest paid of -5,927.37 is displayed in the x register.

To see the remaining principal, tap  97,330.21 is displayed.

Note that 12 was added to the N (number of periods) to give the starting period for more amortization calculations for this loan.

## Simple interest example:

Also see:

What is the simple interest for a load of 450 at 7% for 60 days?

60 Stores the number of days

7 Stores the interest rate

-450 Stores the amount of the loan.  Calculates the interest: • The x register contains 5.25, the interest based on 360 days.
• The z register contains 5.18, the interest base on 365 days.

The following apply to RPN calculation mode.

• The y register contains the positive loan amount, so tapping will calculate the total principal and 360 day interest, 455.25.

To calculate the 365 day principal and interest, press  to get 455.18.
