Present Value of an Ordinary Annuity:
= P x [1 – (1 i)-N] / i
Future Value of an Ordinary Annuity:
= P x [(1 I)N – 1 ) ] / I
- P = charge or amount of cash
- N = number of periods or trades
- I interest
For your receipt or charge of cash to be considered a loan, it must have every one of the following features:

On January 1 st, Bill decided he would deposit $5,000 in the conclusion of each and every year to his retirement accounts fully for its subsequent twenty decades. The interest rate earned on that money is going to be 5 percent. Bill want to calculate the present value and future price with this retirement accounts balance by the close of twenty decades.
Present value of an ordinary annuity:
= 5,000 x [1 – (1 0.05)-20] / 0.05
= 5,000 x [1 – (1.05)-20] / / 0.05
= 5,000 x [1 – 0.37689] / / 0.05
= 5,000 x [0.62311] / / 0.05
= 5,000 x 12.462, or even $62,311.05
Future value of an ordinary annuity:
= 5,000 x [(1.05)20 – inch ] / 0.05
= 5,000 x [2.6533 – inch ] / 0.05
= 5,000 x [1.6533] / / 0.05
= 5,000 x 33.0660, or even $165,329.77
