An ordinary annuity is a series of equal payments made at regular intervals, typically annually or semi-annually. The present value, payment amount, interest rate, and number of periods are the key attributes of an ordinary annuity. The present value represents the lump sum value of all future payments at the beginning of the annuity, while the payment amount refers to the amount of each payment. The interest rate determines the rate of return on the annuity investment, and the number of periods indicates the duration of the annuity payments.
Understanding the Structure of an Ordinary Annuity
An ordinary annuity is a financial instrument where a series of equal payments are made at regular intervals over a specified period. Here’s a detailed breakdown of its key components:
1. Payment Amount
- This refers to the fixed sum that is paid at each payment interval.
- It can be monthly, quarterly, semi-annually, or annually.
2. Time Period
- It is the total duration of the annuity payments.
- Can range from a few months to several decades.
3. Interest Rate
- For non-zero interest rates, the interest earned on unpaid installments is added to the payment amount before each subsequent payment.
- The interest rate is usually fixed throughout the annuity period.
4. Present Value
- It is the initial lump sum that would yield the same net future cash flow as the annuity.
5. Future Value
- The value at the end of the annuity period if the payments were invested at the given interest rate.
6. Payment Frequency
- This determines how often payments are made.
- Common options include monthly, quarterly, semi-annually, or annually.
7. Present Value Factor
- A factor used to calculate the present value of the annuity given its payment amount, time period, and interest rate.
8. Payment Factor
- A factor used to calculate the payment amount of the annuity given its present value, time period, and interest rate.
9. Accumulation Factor
- A factor used to calculate the future value of the annuity given its payment amount, time period, and interest rate.
