How to calculate the NPV?
To calculate NPV, you find the Present Value (PV) of all future cash inflows and subtract your initial investment.
The Formula:

r: The discount rate (e.g., 0.10 for 10%).
t: The year number.
How to calculate NPV for 4 years?
Calculating for a 4-year period involves discounting each year's income back to "today's shillings" and summing them up.
Year 1: Income ÷ (1 + r)¹
Year 2: Income ÷ (1 + r)²
Year 3: Income ÷ (1 + r)³
Year 4: Income ÷ (1 + r)⁴
Final Step: Add these four values together and subtract what you spent at the start.
