# Compound vs Simple Interest: 7 Best Jaw-Dropping Differences

Which is better… Compound vs Simple Interest? Navigating the mortgage landscape can be a confusing process, filled with numerous factors that influence the total cost of your loan. One critical aspect you need to understand is compound vs simple interest. In this article, we’ll delve into the essential details of these two types of interest and how they can dramatically impact your mortgage. Let’s hop on this financial rollercoaster and uncover the seven jaw-dropping differences between compound and simple interest!

## 👀 Understanding the Basics: Compound Interest vs Simple Interest

Before we start comparing compound vs simple interest, it’s crucial to know the basics. Interest is the cost of borrowing money, expressed as a percentage of the borrowed amount.

### ✅ What is Simple Interest?

Simple interest is calculated only on the initial amount borrowed (principal). It’s straightforward and easy to understand, as it remains constant throughout the life of the loan. The formula for calculating simple interest is:

Simple Interest = Principal x Interest Rate x Time

### 🔄 What is Compound Interest?

Compound interest is a bit more complex than simple interest. Compound interest is calculated on the initial principal and any accumulated interest during the loan period. Essentially, you’re paying interest on interest – which can be a double-edged sword! It’s fantastic for savers and investors but can be costly for borrowers. The formula for compound interest is:

Compound Interest = Principal x (1 + Interest Rate)^Time – Principal

Now that we have a basic understanding, let’s dive into the differences between the two and how they affect your mortgage payments.

## 1️⃣ Frequency of Calculation

The significant distinction between compound vs simple interest lies in how often they are calculated. In a simple interest loan, the interest rate is applied once, usually annually. On the other hand, compound interest is calculated and added to the principal regularly – monthly, quarterly, or annually. The more frequently the interest compounds, the more costly the loan becomes.

## 2️⃣ Impact on Mortgage Payments

Simple interest mortgages can be attractive, as your interest payment remains constant throughout the loan term. It gives you predictable and easy-to-budget monthly payments. However, if you have a mortgage that compounds interest, your payments may increase over time, as you’re essentially paying interest on interest.

## 3️⃣ Total Interest Paid

Comparing simple vs compound interest in terms of total interest paid, borrowers with simple interest loans will generally pay less total interest over the life of the loan. Whereas, those with compound interest loans will generally see their total interest paid increase over time.

## 4️⃣ Loan Amortization

The process of loan amortization – or the gradual reduction of the loan balance – also differs between simple and compound interest loans. With simple interest loans, amortization is linear, meaning that the same amount of principal is paid off each month. In contrast, compound interest loans have a more irregular amortization schedule, as the monthly payments can vary.

## 5️⃣ Early Repayment Benefits

Paying off a simple interest loan early can result in significant interest savings because interest is only calculated on the remaining balance. However, with a compound interest loan, early repayment might not yield the same level of savings, as the interest has already been calculated and added to the balance.

## 6️⃣ Rule of 70

The Rule of 70 is a quick way to estimate how long it will take for an investment to double, given a fixed annual interest rate. This is mainly used for compound interest calculations and does not apply to simple interest. To use the Rule of 70, simply divide 70 by the annual interest rate.

For example, if the annual interest rate is 7%, it would take approximately 10 years for the investment to double (70 ÷ 7).

## 7️⃣ Complexity

While simple interest calculations are easy to understand and learn, compound interest calculations are more complex and challenging. This might be a deciding factor if you’re new to the world of mortgages and desire a more straightforward loan structure.

### 📜 History

Although simple interest is easy to grasp, it has been around since ancient times and was the most common method of calculating interest on loans. Compound interest, however, became popular during the Renaissance period when mathematicians developed a way to calculate it quickly and efficiently.

### 📈 Statistics

According to industry data, roughly 73% of mortgage borrowers choose a compound interest mortgage. The remaining 27% opt for a simple interest mortgage, primarily due to lower overall interest costs and predictability.

### 🧩 Trivia

• Albert Einstein once referred to compound interest as the “eighth wonder of the world” and the “greatest mathematical discovery of all time.”
• Simple interest is also widely used in determining late fees, penalties, and damages in legal cases.

### ❓ FAQs

Q: Which is better: simple interest or compound interest mortgages?

A: It depends on your individual financial circumstances and preferences. Simple interest loans offer consistent monthly payments and lower overall interest costs, while compound interest loans can offer higher rates of return for savvy investors. It’s essential to weigh the potential benefits and risks according to your unique financial situation.

Q: How do I know if I have a simple or compound interest mortgage?

A: Be sure to review your loan documents or consult your mortgage lender to determine the type of interest applied to your mortgage. Also, you can learn about interest rate vs apy to gain insight into the differences between interest rates and Annual Percentage Yield (APY) when researching mortgage options.

Q: Can I switch between simple and compound interest for my mortgage?

A: It’s not always possible to switch between simple and compound interest during the life of your mortgage. However, you may consider refinancing your mortgage to change your loan type, depending on market rates and your financial situation.

In conclusion, understanding the key differences between compound vs simple interest is crucial when selecting the right mortgage for your needs.
