4 Must Know Financial Functions in Excel

One of the most powerful features of Excel for finance professionals is its ability to perform financial calculations efficiently. The following financial functions in excel introduced by LammocOffice will certainly be useful for processing economic data and financial analysis.

1. PV Function – Calculating Present Value

Definition of PV Function

The PV function stands for “Present Value.” It calculates the present value of a cash flow based on its future value. Below is a detailed guide on how to use the PV function.

Syntax of the PV Function

=PV(rate, nper, pmt, [fv], [type])

Required Parameters:

• rate – Interest rate per period
• nper – Number of payment periods
• pmt – Fixed periodic payment amount; if pmt = 0, you must input fv (do not leave this parameter empty)

Optional Parameters:

• fv – Future value of the cash flow; if omitted, pmt must be provided
• type – Specifies when payments are due:
  • type = 0 (default): Payments are made at the end of each period
  • type = 1: Payments are made at the beginning of each period

Notes on Using the PV Function

The PV function provides accurate results only when all input values are consistent, especially rate and nper.

• If payments are made monthly, divide the annual interest rate by 12 (rate = 10%/12) and multiply the number of years by 12 (nper = 4*12 for a 4-year loan).
• If payments are made annually, use the interest rate as given (rate = 10%) and set nper = 4 for a 4-year term.

Example 1: Loan Calculation

You borrow $10,000 at 5% annual interest, to be paid monthly over 3 years.

=PV(5%/12, 3*12, -300)

Result: -$9,976.55 (close to the loan amount due to rounding).

2. FV Function – Calculating Future Value

Definition of FV Function

The FV function stands for “Future Value.” It calculates the future value of a cash flow based on a fixed interest rate, fixed periodic payments, and the total number of periods.

Syntax of the FV Function

=FV(rate, nper, pmt, [pv], [type])

Required Parameters:

• rate – Interest rate per period
• nper – Number of payment periods
• pmt – Fixed periodic payment amount; if pmt = 0, you must input pv

Optional Parameters:

• pv – Present value of the cash flow; if omitted, pmt must be provided
• type – Specifies when payments are due (same as PV function)

Notes on Using the FV Function

Ensure consistency in input data, similar to the PV function.

Example: Savings Account Growth

You invest $200 per month for 5 years in an account with an annual interest rate of 6% (compounded monthly).

=FV(6%/12, 5*12, -200, 0, 1)

Result: $13,931.47 (total amount after 5 years).

3. NPV Function – Calculating Net Present Value

Definition of NPV Function

The NPV function (Net Present Value) calculates the net present value of an investment based on a discount rate and a series of future cash inflows and outflows.

Syntax of the NPV Function

=NPV(rate, value1, [value2],…)

Parameters:

• rate – Discount rate
• value1, value2, … – Cash flows (negative for outflows, positive for inflows)

Notes on Using the NPV Function

Unlike the PV function, which assumes constant cash flows, the NPV function allows varying cash flows over time.

Example: Simple NPV Calculation

You invest $10,000 today in a project expecting cash flows of $3,000, $4,000, and $5,000 over the next three years at a 10% discount rate.

=NPV(10%, 3000, 4000, 5000) - 10000

Result: $1,157.67 (a positive NPV indicates a profitable investment).

4. PMT Function – Calculating Fixed Payments for Loans or Investments

Definition of PMT Function

The PMT function (Payment) calculates the fixed payment amount required to repay a loan or meet an investment goal.

Syntax of the PMT Function

=PMT(rate, nper, pv, [fv], [type])

Parameters:

• rate – Interest rate per period
• nper – Total number of payment periods
• pv – Present value of the loan or investment

Notes on Using the PMT Function

Refer to the PV function for more details.

Example: Loan Payment Calculation

You take a $20,000 loan with an annual interest rate of 5%, to be repaid monthly over 5 years.

=PMT(5%/12, 5*12, -20000)

Result: -$377.42 (monthly payment).
