The image above represents present worth. To calculate present worth, three essential parameters are needed and these parameters are First Payment (A1), Interest Rate (i) and Number of Year(s) (N).
The formula for calculating present worth:
P = A₁[N / (1 + i)]
Where:
P = Present Worth or Amount
A₁ = First Payment
i = Interest Rate
N = Number of Years
Let’s solve an example;
Find the present worth when the first payment is 8, the interest rate is 0.3 and the number of years is 22.
This implies that;
A₁ = First Payment = 8
i = Interest Rate = 0.3
N = Number of Years = 22
P = A₁[N / (1 + i)]
Then, P = 8[22 / (1 + 0.3)]
P = 8[22 / 1.3]
So, P = 8 x 16.92
P = 135.38
Therefore, the present worth is ₦135.38.
