Using the t1-83 plus TVM solver or similar tool. create complete tables like the following to see which option is the most effective investment. the choices are monthly payments of $200 at annual interest rate 5% for 10 years(option A). doubling the payments (option B). doubling the interest (option C) or having the payment/compounding periods take place twice as often (option D). STATE WHICH OF THESE OPTIONS IS THE BEST AND WHY IT IS THE MOST EFFECTIVE. https://imgur.com/a/UFjWYIx don't have the tvm solver any one can help thanks 2. ## Re: tvm solver You should be able to download a free trial of the TI calculator. Or the equivalent Casio calculator fx9860G. Just google it. 3. ## Re: tvm solver The "calculator" used is of no importance. A "financial formula" is required for each of the 4 options. The present values (or future values) are compared. If you want to "see it in action", state each option IN DETAIL. 4. ## Re: tvm solver Yes it can be done manually by using the compound interest formula. But the way the question is worded, it seems to be an exercise in tvm usage on a calculator. 5. ## Re: tvm solver 6. ## Re: tvm solver Originally Posted by Cervesa entered the information but can't find the result button??? sorry don't know how to use it can someone show how a sample results https://imgur.com/a/HdjQlDS 7. ## Re: tvm solver Your present value is 0, your payment is 200. Once you enter details about interest rate and time for each option, press the FV (future value) button. 8. ## Re: tvm solver Originally Posted by Debsta Your present value is 0, your payment is 200. Once you enter details about interest rate and time for each option, press the FV (future value) button. okey i used another site and this is what i got let me know if its right thankz https://imgur.com/a/UceAtwJ 9. ## Re: tvm solver YES...31056 is correct. But I don't understand why you're running around looking for calculators. Can't you use the standard formula in Toronto? f = a*[(1 + r)^n - 1] / r a = monthly deposit amount (200) n = number of monthly deposits (10*12 = 120) r = monthly interest rate (.05/12 = .004167) f = future value (?) f = 200*[(1 + .00417)^120 - 1] / .004167 = 31056 10. ## Re: tvm solver thanks much because they want us to learn how to use calculators not formulas ... the calculator is expensive so i try to find a free website offer tvm solver. so how to calculate the total interest? thanks much 11. ## Re: tvm solver Originally Posted by yorkmanz so how to calculate the total interest? thanks much Why do you need total interest? Your original question was: Using the t1-83 plus TVM solver or similar tool. create complete tables like the following to see which option is the most effective investment. the choices are monthly payments of$200 at annual interest rate 5% for 10 years(option A). doubling the payments (option B). doubling the interest (option C) or having the payment/compounding periods take place twice as often (option D).
You can just compare your future value to see which is most effective.

To calculate total interest you need to subtract all your $200 payments (how many were there?) from the future value calculated. This difference is the total interest. (What else could it be?) 12. ## Re: tvm solver here is my answers can someone correct if i am wrong thanks https://imgur.com/a/mmBujDP 13. ## Re: tvm solver what type of annuity is this Is THIS CONSIDERED AS AN ordinary annuity or annuity due? Future Value:$31,185.86

If 1st deposit at beginning of 1st period: annuity due.
If 1st deposit at end of period: ordinary annuity.
