TI-84 TVM Solver Finance Guide
TI-84 TVM Solver Finance Guide
Quick answer: The TI-84 TVM solver lives in the Finance menu (APPS → 1:Finance → 1:TVM Solver). Enter the known values — N, I%, PV, PMT, FV, P/Y, C/Y — move your cursor to the unknown, and press ALPHA then ENTER to solve. For example, a $10,000 loan at 6% over 60 months gives a payment of about $193.33.
Where to Find the TI-84 TVM Solver
Press APPS, choose 1:Finance, then 1:TVM Solver. You will see a single screen listing the variables N, I%, PV, PMT, FV, P/Y, C/Y, plus a PMT: END/BEGIN row at the bottom. That one screen is the entire workspace — everything in this guide happens there, and the same menu layout works across the TI-84 Plus family, including the Plus CE.
What Each TVM Variable Means
- N — the total number of payment periods. For a 5-year loan with monthly payments, N = 60.
- I% — the annual interest rate, entered as a whole number. For 6% interest, type 6, not 0.06.
- PV — present value: the amount of the loan right now. Money you receive counts as positive.
- PMT — the payment made each period. This is usually the unknown you are solving for.
- FV — future value: what remains after the last payment. For a fully paid-off loan, FV = 0.
- P/Y — payments per year. Monthly payments mean P/Y = 12.
- C/Y — compounding periods per year. On most consumer loans this matches P/Y, so it is also 12. When you enter P/Y, the calculator automatically sets C/Y to match — just double-check it.
- PMT: END/BEGIN — whether each payment happens at the end (END) or the beginning (BEGIN) of the period. Ordinary loans use END, which is the default.
Worked Example: Monthly Payment on a $10,000 Loan
Let’s find the monthly payment on a $10,000 loan at 6% annual interest, paid off over 5 years.
- Open the solver: APPS → 1:Finance → 1:TVM Solver.
- Type 60 next to N, then press ENTER.
- Type 6 next to I%, then press ENTER — whole number, not 0.06.
- Type 10000 next to PV, then press ENTER.
- Type 0 next to PMT, then press ENTER. It is the unknown; entering 0 simply clears any old value.
- Type 0 next to FV, then press ENTER.
- Type 12 next to P/Y, then press ENTER. C/Y updates to 12 automatically.
- Move the cursor up to PMT, then press ALPHA followed by ENTER to solve.
The calculator shows PMT = -193.33. That means a monthly payment of about $193.33. The negative sign is not an error — it is the sign convention, explained in the next section.

Understanding the Sign Convention
The TVM solver treats money flowing in as positive and money flowing out as negative. You received the $10,000 loan (positive PV), so the payments you make are negative (money leaving you). If you entered PV as -10000 instead, the solved payment would appear as +193.33. The size of the number is what matters for your budget — the sign only tracks the direction of the cash flow.
3 Common TVM Solver Mistakes
- Forgetting to set P/Y. The default is 1 payment per year. For a monthly loan you must set P/Y = 12, or your answer will be wildly off.
- Entering the rate as a decimal. I% expects a whole number: type 6 for 6%, never 0.06.
- Leaving old values on screen. The solver remembers your previous entries. Before starting a new problem, enter every variable fresh — never assume the screen is blank.

Frequently Asked Questions
Where is the TVM solver on the TI-84 Plus CE?
In the same place as on every TI-84 Plus model: press APPS, select 1:Finance, then 1:TVM Solver.
Why is my payment negative?
That is the sign convention at work: money in is positive, money out is negative. A positive loan amount (PV) produces negative payments. The payment is $193.33 either way.
What is the difference between P/Y and C/Y?
P/Y is how often you make payments per year; C/Y is how often interest compounds per year. On most consumer loans they are equal. Set P/Y, and the calculator matches C/Y for you automatically.
Can the TVM solver find the interest rate?
Yes. Enter N, PV, PMT, FV, P/Y, and C/Y, move the cursor to I%, and press ALPHA + ENTER to solve for the rate instead.
Does the TVM solver work for savings goals too?
Absolutely — it is the same time-value-of-money math. Set your goal as FV and your monthly deposit as PMT, then solve for N to see how many months it takes. Wikipedia’s article on the time value of money explains the underlying concept.
How do I clear the TVM solver before a new problem?
The solver keeps your last entries, and there is no single clear-all key for it. The reliable method is simply to enter every variable fresh for each new problem.
