NPV Calculator

+ +## Description :- + +Given an initial investment, the discount rate (per year), and the yearly cash flows, this calculator calculates the NPV (Net Present Value) of the investment. NPV is a financial metric used to evaluate the profitability of an investment or project. + +## Tech Stacks :- + +- HTML +- CSS +- JavaScript + +## Formula Used :- + +The formula for calculating NPV is: + +\[ NPV = \sum \left( \frac{CF_t}{(1 + r)^t} \right) - C_0 \] + +Where: +- \( CF_t \) is the cash flow at time \( t \) +- \( r \) is the discount rate +- \( C_0 \) is the initial investment +- \( t \) is the time period (year) + +## Screenshots :- + +![image](https://github.com/Manav173/CalcDiverse/assets/73993775/640d6aa4-b68b-4057-865c-bee17e8c7e1b) diff --git a/Calculators/NPV-Calculator/index.html b/Calculators/NPV-Calculator/index.html new file mode 100644 index 000000000..61bb80cb3 --- /dev/null +++ b/Calculators/NPV-Calculator/index.html @@ -0,0 +1,36 @@ + + + + + + + + NPV Calculator + + + +
