by SLV Team 50 views

Hey there, finance enthusiasts! Let's dive into a common yet crucial financial concept: calculating the future value of an ordinary annuity. In this article, we'll break down how to find the savings plan balance after one year, considering an Annual Percentage Rate (APR) of 13% and monthly payments of $100. We'll explore the formula, the components, and finally, determine the correct answer from the provided options. Understanding this calculation is fundamental for anyone looking to make informed decisions about their savings and investments. So, buckle up, and let's get started!

First off, what is an ordinary annuity? It’s a series of equal payments made at the end of each period. In our scenario, those periods are months, and the payments are $100. This is different from an annuity due, where payments are made at the beginning of each period. Understanding this distinction is key because it affects how we calculate the future value. The future value helps us determine how much our money will grow over a specific time, considering the interest earned.

To begin, let’s introduce the formula for the future value of an ordinary annuity. It's a bit complex at first glance, but we'll break it down step by step to make it easier. The formula is: FV = P * (((1 + r)^n - 1) / r), where:

  • FV = Future Value (the amount we want to find)
  • P = Payment amount per period ($100 in our case)
  • r = Interest rate per period (annual interest rate divided by the number of compounding periods per year)
  • n = Number of periods (total number of payments)

Now, let's translate these formulas and figure out how to solve them in a simple way. The formula might seem intimidating at first, but with a bit of practice and patience, it becomes manageable. Let's make sure we get this right! The key is to break down each part of the formula and understand how it relates to our specific scenario. By understanding the components of the formula, you can apply it to various financial situations.

In our case, the payment amount per period (P) is $100. The number of periods (n) is 12 since we're looking at one year with monthly payments. The interest rate per period (r) is the annual interest rate of 13% divided by 12, which is 0.13/12 = 0.01083333. It's important to be accurate with these figures because a slight error can lead to a considerable difference in the final result, especially over extended periods. Let's calculate each element separately to ensure we understand its meaning. This will give us a clear view of how each part contributes to the overall calculation, and we can find the future value!

Diving into the Calculation: Step-by-Step

Alright, folks, let's roll up our sleeves and crunch some numbers! We've got our formula, and we've identified all the necessary components. It's time to put it all together. Here's how we'll solve this, step by step, to ensure we get the right answer and help you get comfortable with the calculations. Remember, the goal is to find the Future Value (FV) after 1 year.

First, we'll calculate the interest rate per period (r): r = 0.13 / 12 = 0.01083333. This represents the monthly interest rate. Then, we plug all the values into the formula: FV = 100 * (((1 + 0.01083333)^12 - 1) / 0.01083333). Don't worry, we'll break this down further.

Now, let's simplify the equation. Calculate the value inside the parentheses first. You can use a calculator or spreadsheet for this part to make sure your calculations are correct. Calculate (1 + 0.01083333)^12 which is roughly equal to 1.137873. Then, subtract 1 from this result: 1.137873 - 1 = 0.137873. Finally, divide by the monthly interest rate: 0.137873 / 0.01083333 = 12.726217. Then, multiply by the payment amount: 100 * 12.726217 = 1272.6217. So, the Future Value after 1 year is approximately $1,272.62.

The calculation involves several steps, each critical to achieving the correct result. The first step, determining the interest rate per period, is crucial. If the period and interest rate do not align, the final result will be inaccurate. After that, we apply each number to the formula, following the order of operations to solve each item inside the parentheses. These steps might seem simple but are crucial to accurately calculate the future value. Always take your time to ensure all the calculations are correct, especially when working with financial matters. These calculations ensure accuracy and provide a reliable foundation for financial decisions.

Analyzing the Answers

So, after all the calculations, which of the provided options is the closest to our result? Let's take a look at the options:

A. $1,271.18 B. $1,272.17 C. $1,273.16 D. $1,274.15

Our calculated future value is approximately $1,272.62. Now, let’s compare our calculated value with the provided options. Which one is closest? The correct answer is B. $1,272.17. This demonstrates how precise calculations and a solid understanding of financial formulas can lead us to the correct answer. The minor differences in the answers might arise from rounding or slight variations in the calculation steps. Remember, in financial calculations, even a small difference in the inputs can affect the outcome. It's important to understand the concept and method for arriving at the answer.

This exercise highlights the importance of understanding financial calculations and formulas. It's not just about memorizing the formula, it's also about understanding the components, the context, and how to apply it in real-world scenarios. This knowledge is invaluable, especially when it comes to personal finance, investments, and planning for the future. With a grasp of these fundamental concepts, anyone can make well-informed decisions regarding their financial well-being.
