TVM Calculator — Step-by-Step Guide
💡
First, understand the 5 variables:
N = Number of periods (5 years = 5; if semi-annual = 5×2=10)I/Y = Interest rate per period (6% annual = enter 6; semi-annual = 6÷2=3)PV = Present Value — amount you invest or borrow todayPMT = Payment per period — regular deposits/withdrawals (0 if none)FV = Future Value — amount you receive or owe later
1
Always reset before a new problem! Press keyboard
D (or 2ND → FV). Old values will give wrong answers.
2
Enter the known value as a number, then press the corresponding variable key to store it. Example: Period is 5 years → enter
5 → press N key (when 5.00 appears, it's saved!)
3
Fill in the remaining 4 variables the same way. Leave only 1 unknown variable blank — you'll solve for that one.
4
Press
CPT, then press the variable key you want to solve for. The answer appears. Example: Want future value → CPT → FV
⚠️
Sign convention is critical! Money going out (investment, loan principal) = negative (−). Money coming in (returns, maturity payment) = positive (+). Use
+/− to toggle signs. Wrong signs = "Error".
Example: Invest $10,000 at 6% annual rate for 5 years. What's the future value?
①
③
⑤
→ FV = $13,382.26
💬 "What if interest compounds semi-annually?"
6% annual, semi-annual compounding: Change N=10 (5×2), I/Y=3 (6÷2). Match the period units!
①
D (reset) → ② 5 → N (5 years)③
6 → I/Y (6% annual) → ④ 10000 +/− → PV (money out = −)⑤
0 → PMT (no deposits) → ⑥ CPT → FV→ FV = $13,382.26

NPV — Is This Investment Worth It?
💡
What is NPV? If you invest $50,000 today and receive $15,000/year for 5 years, NPV tells you in one number if it's profitable. NPV > 0 = good investment; NPV < 0 = avoid.
1
Press
CF → Display shows CF0 (initial investment). Enter the amount as negative (money out) and press ENTER.
2
Press
↓ → C01 appears (Year 1 inflow). Enter the amount, press ENTER. Press ↓ again → F01 (frequency: how many years receive this amount). Enter 5 if you receive the same payment for 5 years.
3
After all entries, press
NPV. When "I=" appears, enter the discount rate (your required return). Press ENTER → ↓ → CPT to calculate.
예제: 5,000만원 투자, 매년 1,500만원 × 5년, 기대수익률 8%
①

⑤
→ NPV = 9,869,070원 (양수 = 투자 가치 있음!)
💬 "매년 받는 금액이 다르다면?"
C01에 1년차 금액, F01은 1, C02에 2년차 금액, F02는 1… 이렇게 하나씩 입력하면 됩니다.
①
CF → 50000000 +/− ENTER (초기 투자금, −)②
↓ → 15000000 ENTER (매년 받는 돈)③
↓ → 5 ENTER (5년 반복)④
NPV → 8 ENTER (기대수익률 8%)⑤
↓ → CPT→ NPV = 9,869,070원 (양수 = 투자 가치 있음!)
💬 "매년 받는 금액이 다르다면?"
C01에 1년차 금액, F01은 1, C02에 2년차 금액, F02는 1… 이렇게 하나씩 입력하면 됩니다.
IRR — What's the Real Return Rate?
💡
What is IRR? It tells you "What is the annual return rate of this investment?" Unlike NPV (where you set the discount rate), IRR calculates it automatically. If IRR > your required return, it's a good investment!
1
Enter cash flows using
CF exactly like you did for NPV. (Same sequence: CF0 → C01 → F01)
2
After all entries, press
2ND → NPV. You'll notice "IRR" is written above the NPV key — pressing 2ND activates that second function.
3
Press
CPT and done! Do NOT enter a discount rate — the calculator automatically finds the return rate.
Example: Invest $50,000, receive $15,000/year for 5 years. What's the real return?
①
②
③
→ IRR = 15.24%
💬 Interpretation: The real return is 15.24% annually. If your required return is 8%, this is an attractive investment.

Reset & Setup — Must Know
⚠️
Most common mistake #1: NOT resetting before a new problem! Old values remain and give wrong answers. New problem = ALWAYS reset first.
1
Reset TVM only (most frequent):
2ND → FV or keyboard D. Sets N, I/Y, PV, PMT, FV all to 0. Do this before every TVM problem!
2
Full Reset (factory reset):
2ND → CE/C or keyboard R. Clears TVM + memory + cash flows. Use when calculations get messy.
3
BGN/END Toggle:
2ND → PMT. Switches between Beginning (BGN) and End (END) of period. Most problems use END (default). When "BGN" appears at top, you're in Beginning-of-period mode.
4
Store/Recall values: Save interim results with
STO + digit (0–9). Retrieve with RCL + same digit. Up to 10 storage slots.
