About Compound Interest Percentage Calculator

Compound Interest Percentage Calculator helps you to calculate the amount money can grow over time when interest is compounded. The interest from each period is added to the principal and future interest is calculated. Compound Interest grows exponentially unlike Simple Interest where growth is linear.

The formula of the calculator consists of: Final Amount (A), Principal Amount (P), Annual Interest rate (R), Number of compounding periods (N) and finally Time (T).

Guide to using the Calculator

1. Open the Calculator

Open the Calculator online for example; PercentagePercentageCalculator.com (this tool works on any browser).

2. Principal Amount

Put your starting amount in the first box. This could be your initial deposit, investment or your loan principal.

3. Interest Rate

Enter your annual interest rate as a percentage.

4. Time Period

Next, enter the length of time the money will be invested or borrowed. This is usually in years however some calculators will let you use days or months also.

5. Compounding Frequency

Select how often the interest is compounded; Annually (1), Semi-Annually (2), Quarterly (4) or Daily (365).

6. Calculate

Click on the calculate button. The calculator will then quickly apply the compound interest formula for you.

7. Results

Your results will then instantly be available for you to view. You will typically see the Final Amount (A) and Compound Interest (I). This allows you so review the total after compounding and the extra amount earned, which is the difference between the original principal and the final amount.

Example

To explain how the calculator can help you, here are some examples.

If you were to invest £10,000 at a 5% annual interest rate, compounded monthly for 3 years the compound interest earned is around 16.16% over the three years. This is calculated by taking the 10,000 (P), 0.05 (R), 12 (N) and 3 (T).

Why It’s Helpful

Summary

Using a Compound Interest Percentage Calculator is fast and easy. You simply need to enter the principal, the annual interest rate, the time period and the compounding frequency. Then, click calculate. The tool will then immediately show you both the total future amount and the interest earned.

The tool is valuable as it can allows you to clearly visualize the effect of how compound interest grows faster than simple interest. You could be trying to compare savings accounts at a range of banks, projecting investment returns or planning loan repayments. This calculator allows you to understand exponential growth accurately. The calculator is also simple to navigate and anyone can access it easily on any device (supported on desktop, mobile and tablets).

FAQs

What is a Compound Interest Percentage Calculator?

A Calculator for Compound Interest Percentage assists you in calculating the amount the money could increase over time when the interest compounded. It demonstrates how the interest earned from each month adds to principal and how future interest is calculated using the current total. This is different with Simple Interest, where growth is linear. Compound Interest increases exponentially.

What do the results mean?

After calculating, the results will show The Final Amount (A) and the Compound interest (I). The Final Amount is the sum after compounding while the Compound Interest shows the extra amount that is earned (the variation between principal amount and what is left of the principal).

What are the reasons to use the Compound Interest Calculator instead making calculations by hand?

The calculator can simplify complex calculations particularly for compounding that is frequent. It helps save time, reduces errors and ensures accuracy. It also offers flexibility because it allows different frequency of compounding and offers immediate results. Furthermore, it shows both the amount of interest earned as well as the amount paid out.
