Why Focusing on Monthly Payments Is the Wrong Approach to Your Personal Loan

Just because a monthly payment wouldn't break the bank doesn't mean a personal loan is a good idea.

When applying for a personal loan, many people focus on one thing and one thing only: whether they can afford the monthly payment. And, indeed, many lenders encourage this type of thinking by touting how affordable the loan payments are each month.

While you need to make sure you can pay the loan bill when it comes due, monthly payment is just one factor affecting the total cost of your loan -- and it’s not necessarily the most important factor. Focusing on monthly payments at the expense of looking at the big picture can be a big mistake, and it’s important to understand why.

Here are a few key reasons why you need to look beyond whether your loan payment would fit within your monthly budget.

Lenders make monthly payments look more affordable by stretching out the loan term

Lenders want you to view loans as affordable, and they know many people focus only on the monthly payments that they’ll have to make. Lenders capitalize on this short-term thinking by advertising loans with “payments as low as $X per month.”

The problem is, when you see this “low monthly payment” and it seems like it will fit well into your budget, you may forget to look at just how long the lender expects you to take to pay back your loan. Lenders know this, so they often quote those very low monthly payments by offering you a loan with a very long repayment timeline.

Unfortunately, with a loan that has a long repayment timeline, you pay interest over a very long period of time. Even loans with relatively low interest rates can become expensive when you continue to send monthly interest payments to the lender over a longer amount of time.

A focus on monthly payments obscures the total cost of your loan

With any loan you take out, the number you should focus on isn’t the monthly payment, but the total cost of borrowing. You want to keep this total cost of borrowing as low as possible so you don’t waste a fortune making your lender richer and yourself poorer.

If you focus on monthly payments alone, a loan may not seem that expensive. After all, $50 or $100 a month may seem like pocket change. But if you pay a low monthly payment for a long enough period of time, the costs can really add up.

Say, for example, you take out a $7,000 loan at 10% interest compounded monthly. If you repay the loan over three years, your monthly payment would be $225.87 and the total amount of interest you’d pay would be $1,131.33. While paying over $1,100 in interest is a lot, it’s not ridiculous.
