While formulas help in understanding the logic, using a financial calculator is essential for speed and accuracy, especially in an exam setting. This article explains how to calculate TVM using a financial calculator in a clear, step-by-step manner, focusing on understanding inputs rather than memorising calculator steps.
Understanding Time Value of Money Before Using the Calculator
The principle is straightforward: money available today is worth more than the same amount in the future, because today’s money can earn returns over time. TVM calculations help quantify this difference by incorporating time, interest rates, and cash flows.
Most TVM problems revolve around five key variables: present value (PV), future value (FV), number of periods (N), interest rate per period (I/Y), and periodic cash flow (PMT). A financial calculator allows you to compute any one of these variables when the other four are known.
Financial Calculators Used for TVM Calculations
This explanation focuses on the BA II Plus, as it is more commonly used by CFA candidates and easier for beginners to operate.
TVM Keys and Sign Convention
Cash outflows and inflows must have opposite signs. For example, if you invest money today, the present value is entered as a negative number, while the future value received later is positive. Ignoring sign convention is one of the most common causes of incorrect answers in TVM calculations.
Clearing the Calculator Before Every Calculation
On the BA II Plus, press 2nd → CLR TVM.
This step ensures that no previous values affect your calculation. In exams, forgetting to clear the TVM keys often leads to avoidable errors.
Calculating Future Value Using a Financial Calculator
To calculate the future value, enter the number of periods (N) as 5, the interest rate (I/Y) as 8, the present value (PV) as –10,000, and set the periodic payment (PMT) to zero. Press the ‘CPT’ key and then press the FV key then gives the future value of the investment, representing how the amount grows after compounding over five years.
Calculating Present Value Using a Financial Calculator
Enter N as 4, I/Y as 10, the future value (FV) as 50,000, and PMT as zero. Pressing the ‘CPT’ key and then pressing the PV key gives the present value, which appears as a negative number to indicate a cash outflow today.
TVM Calculations with Periodic Cash Flows
For example, if you invest ₹1,000 at the end of every year for six years at an interest rate of 7%, enter N as 6, I/Y as 7, PMT as –1,000, and PV as zero. Press the ‘CPT’ key and then press the FV key calculates the future value of this ordinary annuity.
Ordinary Annuity and Annuity Due in TVM Calculations
If payments occur at the beginning of each period, the calculator must be switched to BGN (begin) mode to correctly calculate values. This distinction is especially important in problems involving pensions, leases, or savings plans.
Where Students Commonly Make Mistakes in TVM Questions
Most TVM errors are not conceptual but procedural. Common issues include forgetting to clear the calculator, entering the interest rate in the wrong periodic form, ignoring sign convention, and using the incorrect annuity mode.
TVM calculations reward consistency and careful setup more than mathematical complexity.
around planning, progress, or expectations.
A structured preparation approach, realistic planning, and consistent routines help reduce anxiety and improve preparation quality. Calm, disciplined preparation almost always leads to better outcomes than panic-driven effort.
How TVM Is Tested in the CFA Exam
Being comfortable with calculator usage allows candidates to focus on understanding the question rather than worrying about calculations under time pressure.

Conclusion
Rather than memorising formulas, candidates should focus on understanding the logic behind TVM and applying it efficiently using the calculator. This approach saves time, reduces errors, and allows better focus on interpreting exam questions.
Frequently Asked Questions
Time Value of Money is the concept that money available today is worth more than the same amount in the future because it can be invested to earn returns over time.
TVM calculations are done by entering four known variables—PV, FV, N, I/Y, or PMT—into a financial calculator and computing the fifth variable based on the problem requirement.
CFA candidates typically use the BA II Plus or HP 12C calculator, both of which are approved by the CFA Institute for TVM and other exam calculations.
Negative values represent cash outflows, while positive values represent inflows. Correct sign convention is essential for accurate TVM calculations.
