Are Personal Loans Fixed or Variable Rate? Quick Guide

Personal loans can have either fixed or variable interest rates. A fixed-rate personal loan keeps the same interest rate for the life of the loan, while a variable-rate personal loan has an interest rate that can rise or fall over time.

The better choice depends on your budget, loan term and comfort with interest-rate changes. Here's how the two options compare and how to decide which one fits your situation.

Key Takeaways

• Fixed-rate personal loans give you a locked-in annual percentage rate (APR) and predictable monthly payments for the life of the loan, which makes budgeting simpler. Most personal loans come with fixed rates.

• Variable-rate personal loans usually start with a lower APR but can shift when the prime rate moves, so your payment may rise or fall over time. You could save on interest or end up paying more.

• Pick fixed if you want steady payments, a longer term or a tight budget.

• Choose variable if your loan term is short, your budget has room and you can handle a rate hike.

The Quick Answer: Fixed vs. Variable Personal Loans

You can find personal loans with both fixed and variable interest rates. If you're not sure which is the better option, here are some quick facts:

Fixed

• A fixed-rate personal loan offers predictable monthly payments that won't change over time.

• Fixed rates are what you get for the life of the loan.

• Most personal loans have fixed rates.

Variable

• Variable-rate loans often start with lower APRs, but they can change at any time based on an index like the Fed prime rate.

• More flexibility in your budget? You might consider a variable-rate loan.

What's the Difference Between Fixed and Variable Personal Loan Rates?

The biggest difference between fixed and variable personal loans is their APR, or the yearly interest rate you'll pay to borrow money including any fees such as origination fees.

Fixed-Rate Personal Loans

With a fixed-rate personal loan, your APR stays the same from day one until you pay the loan off. That means your monthly payment amount will never change.

Unsecured personal loans, which don't require collateral such as a car or a bank account, usually come with fixed APRs.

Having predictable monthly payments makes it easier to incorporate a loan into your budget, since you won't have to anticipate your installment amounts going up or down.

How Variable APR Works

Variable-rate personal loans are often tied to the prime rate, which is influenced by the federal funds rate set by the Federal Reserve. While the Fed sets the federal funds rate, banks establish the prime rate they use to price loans. The prime rate is typically about 3 percentage points higher than the federal funds rate.

When lenders offer a variable-rate personal loan, they usually add a margin on top of the prime rate. That combined rate becomes your APR.

Here's what happens when rates change:

• If the prime rate rises, your APR may increase.

• If the prime rate falls, your APR may decrease.

• When your APR changes, your lender recalculates your monthly payment based on your remaining balance and repayment term.

Example:

• Loan amount: $10,000

• Term length: 36 months

• Starting APR: 8% prime and 8% margin = 16% APR

If the prime rate increases by 0.50%, the new APR is 16.5%, and thus, your monthly payment increases.

Here's a quick comparison of what rate changes mean for your variable-rate loan payment:

Fixed or Variable Personal Loans: Which Costs More Over Time?

Here’s a quick overview of the differences between fixed-rate and variable-rate personal loans that can make one option more expensive than the other over time.

Quick Example

Say you're borrowing $10,000 with a term of 36 months. Here's how that could play out cost-wise with a fixed-rate loan vs. a variable-rate loan. 

Fixed-Rate Loan

Your rate is set at 12% APR and will stay there for the next 36 months. That would translate to:

• Monthly payment: $332.14

• Total interest paid: $1,957.15

• Total cost: $11,957.15

Variable-Rate Loan

Your APR starts lower, say at 9%. But that rate may increase by two percentage points after the first year, bringing it to 11%, and it will stay there for the rest of the loan term. 

Here’s what your payments and interest would look like:

• Year 1 monthly payment: $318

• Year 1 total interest paid: $776.66

• Years 2 to 3 monthly payment: $324.42

• Years 2 to 3 total interest paid: $825.46

• Total interest paid across life of loan: $1,602.12

• Total cost: $11,602.12

Bottom line: This shows that you can end up paying less in total interest with a variable-rate loan — $355.03 less, in this example. But if the APR increase was more dramatic or happened multiple times, the math could favor the fixed-rate option.

Should You Choose Fixed or Variable?

Not sure which one is right for you? Keep in mind that your options will depend on what you qualify for based on your credit history and financial profile. If you have access to both, here's how to think about which one fits your situation best.

Choose a Fixed-Rate Personal Loan If

• You have a tight budget, need a set monthly payment and don't want to risk unpredictable payment increases.

• You're consolidating multiple debts into one loan and want a single, predictable monthly payment rather than juggling variable costs.

• You have a large loan spread over several years and worry a variable rate could adjust many times.

• You're a first-time borrower who prefers simplicity over chasing potential interest savings.

Choose a Variable-Rate Personal Loan If

• You have a shorter loan term, such as one to two years.

• You have flexibility in your budget, so you can handle increased payments if rates move up.

• You feel confident you can afford higher payments if rates rise.

Final Take

• Fixed-rate loans provide payment certainty.

• Variable-rate loans may save money if rates stay low.

• Consider your loan term, budget and risk tolerance before choosing.

• Compare multiple offers before applying.

FAQs

Are personal loans usually fixed or variable rate?

Most personal loans use fixed APRs rather than variable APRs. It's possible to find personal loans with variable rates, but they're just less common.

How does a variable rate on a personal loan change?

Variable rates on personal loans can adjust monthly or annually, depending on the particular lender. They'll spell out how often rates can be adjusted in your loan agreement. 

Can you switch from a variable rate to a fixed rate on a personal loan?

Not on the same loan. However, you may be able to refinance your variable-rate personal loan into a new fixed-rate loan if you qualify. Before refinancing, compare the new APR, fees and repayment terms to make sure the change will save you money.

Can a lender change your fixed rate after you're approved?

A fixed APR on a personal loan usually can't change after you've been approved. This would generally only happen if you refinance your loan.
