What is FGki?

FGki is commonly used in engineering economics for the present value of a future cash flow series that grows at a constant rate. Formula: FGki = F × [( (1+g)^k – (1+i)^k ) / (g-i) ], where F = initial value, g = growth rate (decimal), k = periods, i = interest rate (decimal).

Financial analysis often involves predicting the value of cash flows that grow over time. Whether you’re working in engineering economics, corporate finance, or investment planning, the FGki Calculator is an essential tool for calculating the present or future value of a cash flow series that grows at a constant rate.

This calculator is specifically designed to simplify the process of applying the FGki formula — a formula used to find the equivalent value of a series of cash flows considering growth rates, interest rates, and specific time periods.


What is FGki?

FGki is a term used in engineering economics and finance for evaluating the present or future value of a cash flow series that grows at a constant rate over a number of periods, factoring in a given interest rate.

The standard formula is: FGki=F×(1+g)k−(1+i)kg−iFGki = F \times \frac{(1+g)^k – (1+i)^k}{g-i}FGki=F×g−i(1+g)k−(1+i)k​

Where:

  • F = Initial value (cash flow at the start)
  • g = Growth rate per period (decimal form)
  • k = Number of periods
  • i = Interest rate per period (decimal form)

If the growth rate equals the interest rate, a special case formula is applied: FGki=F×k×(1+g)k−1FGki = F \times k \times (1+g)^{k-1}FGki=F×k×(1+g)k−1


How to Use the FGki Calculator – Step-by-Step

Using the FGki Calculator is straightforward. Just follow these steps:

  1. Enter the Initial Value (F):
    This is the starting amount of your cash flow series.
  2. Input the Growth Rate (g):
    Specify the growth rate as a percentage. For example, enter 5 for a 5% growth rate.
  3. Specify the Number of Periods (k):
    The total time periods over which the cash flows grow.
  4. Enter the Interest Rate (i):
    This is the discount or interest rate per period, also as a percentage.
  5. Click “Calculate”:
    The tool will process your data with a short progress bar and display your FGki result.
  6. Review the Results:
    You’ll see a detailed breakdown of the input values and the calculated FGki value.
  7. Copy or Share Results:
    Use the “Copy” button to store your results or “Share” to send them directly.
  8. Reset if Needed:
    Click “Reset” to clear the form and start a new calculation.

Practical Example

Let’s say:

  • Initial Value (F): 1,000
  • Growth Rate (g): 6%
  • Number of Periods (k): 5 years
  • Interest Rate (i): 4%

Steps:

  1. Input 1000 in the Initial Value field.
  2. Enter 6 in the Growth Rate field.
  3. Enter 5 in the Number of Periods field.
  4. Enter 4 in the Interest Rate field.
  5. Click Calculate.

Result:
The calculator shows the FGki value and a full breakdown of inputs for verification.
