In this video, we learn how to isolate n (the number of periods or payments) in the Future Value of an Ordinary Annuity formula step by step.

The formula used in annuity problems is:

F = x[(1 + i)^n − 1] / i

Many students struggle when the unknown is n, because it appears as an exponent. In this lesson, you will clearly see how to rearrange the formula using algebra and logarithms to make n the subject.

This video explains:

What each variable in the annuity formula represents

How to rearrange the formula correctly

When and why logarithms are required

A clean step-by-step walkthrough to isolate n

Common mistakes students make in exams

This lesson is especially helpful for students preparing for:

Financial mathematics exams

Business math and annuities

Time value of money problems

If you’ve ever felt confused about solving annuity questions where n is unknown, this explanation will give you clarity and confidence.

Final isolated form shown in the video:

n = log[(Fi / x) + 1] / log(1 + i)

Watch till the end to fully understand each step and apply it easily in exams.
