Press the APPS key, select the Finance app, and then TVM_Solver.

For N, enter 5 * 1 2 for 5 monthly payments.
For I%, enter 1 . 9 / 1 2 for the monthly interest rate.
For PV, enter 1 8 0 0 0 for the present value of the loan.
Make sure "END" is highlighted on the bottom line.
Move the cursor to the "PMT" line and press ALPHA ENTER to compute the monthly payment. You'll get a negative number since this represents something you pay out.

What is the formula to figure 4% daily on 380,000.00 ? Or on any amount ?


premium X % X time
so 380,00000 X4/100 X 1 year
it calculated as the amount ( premium ) multiplied by the percentage of 100 multiplied by the period in years or parts of a year
so it can be 100 X 25% or 1/4(25/100) by the period (5 years or daily (1/365 of a year)
This is known as simple interest
compound interest is calculated on remaining premium after payment X the interest rate by the day or week or month
so for example 100 X 4/100 X 1/12 is the first calculation for the month and for the next month the calculation will be premium of 80 ( if a 20 payment was made in the month X 4/100 X 1/12 and so on if payment are made on time
pm the other hand if no payment are made then the premium goes up by the interest rate
so for the next month it is 104 X 4/100 X 1/12 and the month after that 108.16 X 4/100 X 1/12.and so on
banks use compound when calculating home loan repayments and simple interest when paying interest on your deposits
( has to be in the bank for 367 days to get the interest paid )

I cannot get the textbook answer (online calculators are also the same as textbook answer) using my sharp calculator EL738: Monthly payment for $184,500 at 6.75% interest semi annually, for 5 year term...


Your result is for the 6.75% interest compounded monthly. The problem states that the interest is compounded semiannually. This makes a difference in the effective interest rate.

A 6.75% APR compounded semiannually gives an effective interest rate of about 6.864%:
Press 2 , 6 . 7 5 2nd >EFF

Converting this to APR gives about 6.657%:
Press 1 2 , 6 . 8 6 4 2nd >APR

If you use 6.657 for the interest rate instead of 6.75 you should get the correct result.

GOOD QUESTION, Patweetyp...

I've got you covered.

Seeing how it's been three weeks since you posted this there's a chance you've already gotten your answer, but let me go ahead solve this for those out there who may have had the same problem.

Background: There are FIVE TVM Keys; and as you would assume, you MUST input FOUR of them in order for the BA II Plus to solve for the fifth. Now let's get down to business.

1. Hit CLR TVM. [This is just a cleanup maneuver]
1a. Hit ENTER [yes, BA II Plus always needs to be told to store the value, ALWAYS]
2. Type in -2400
3. Hit PV [Since you are investing money at time 0, your present value is negative 2400]
3a. Hit ENTER
4. Type 6
5. Hit I/Y [Your annually compounded interest rate is 6 percent]
5a. Hit ENTER
6. Type 0
7. Hit PMT [you do not have any recurring deposits*]
7a. Hit ENTER
8. Type 1
9. Hit N [there is one year until expiration/liquidation/termination]
9a. Hit ENTER
10. Hit CPT
11. Hit FV [this is your ANSWER = 2544]
----- From here, all you would need to do is change N in order to get your other answers (5 years, 10 years, etc) ----

*If your calculation does not require a recurring payment then you really just have a basic equation of value which would be solved faster by hand. (IE, 2400*(1.06)^1=FV=2544).

You'll notice that I underlined "annually compounded" as well as "one year". The reason for this is because you ALWAYS need your interest term to match your time interval. For instance, if you had monthly payments of which you wanted the year-end total you would need a monthly effective interest rate, and N would be 12.



Okay, I hope that helped. The BAII Plus is the best calculator for time-value-money calculations I've come across. When things get more advanced, you will start using the amortization table which cannot be found in any other TI Calculator (from what I know). TVM is perfect for annuities, mortgages, loans, bonds, and more.

Lent someone my calculator and now when I try to figure a payment it is too great, I put in $100,000 @ 5% 360 Months and it is giving me a payment of $5000.00 not sure how to get it right


You have your payments-per-year set to 1 and the calculator is showing an annual payment of $5000. Press 2nd [P/Y] 1 2 ENTER 2nd [QUIT] to change it to twelve (monthly). Now pressing CPT PMT should give you a monthly payment of $536.82.

Once you're in the TVM solver:
On the top line (N=) type in 5 * 12 ENTER for five years of month payments.
On the I% lline type in 5.5 / 12 ENTER for the month interest rate.
On the PV line type in 18000 ENTER
Make sure the FV is 0 and END is highlighted on the bottom line.
Move the cursor to the PMT line and press ALPHA [SOLVE] (that's ALPHA ENTER) and see -343.82 for the monthly payment.

Yes you can use it, here is the formula: Y= V(t+ (i/c))^(tc) V=amount put in, t=time, i=intrest rate, c= amount of times it is compounded.
