If you have a daily simple interest (DSI) loan, the word “daily” indicates that interest is calculated every day. Thus, the amount you owe on a DSI loan increases with each passing day.

However, because DSI loans use a simple interest calculation, interest does not compound. It’s important to learn how to calculate daily simple interest so you know how much you will owe on a DSI loan.

Taking out a personal loan or financing a major purchase like a car or home often involves dealing with interest charges. The way interest accrues can significantly impact the total cost of borrowing. One option is a daily simple interest loan, which offers predictable interest costs if payments are made on time.

In this comprehensive guide, we’ll explain what daily simple interest is, how these loans work, and the pros and cons to consider.

What is Daily Simple Interest?

With a simple interest loan, borrowers pay interest based only on the outstanding principal balance not on accrued interest. The interest rate is applied to the original loan amount.

Daily simple interest takes this a step further by calculating interest daily rather than monthly or annually. The daily interest rate is determined by dividing the annual interest rate by 365 days. Each day, interest accrues on the current principal balance based on the daily rate.

This differs from compound interest loans where unpaid interest gets added to the principal balance. With daily simple interest loans, accrued interest does not compound if payments are made on time.

How Do Daily Simple Interest Loans Work?

A daily simple interest loan works like this:

  • The lender first determines a daily interest rate based on the annual rate. For example, a 6% annual rate becomes 0.0164% daily (6% / 365 days).

  • Each day, the lender calculates interest by multiplying the principal balance by the daily rate. For example, on a $10,000 balance, daily interest would be $10,000 x 0.0164% = $1.64.

  • The borrower makes scheduled payments, usually monthly. The payment goes first toward paying the accrued interest, then the remainder reduces the principal.

  • If payments are made on time, interest does not compound. The interest for the next period is based only on the updated principal balance after each payment.

  • Making extra payments or paying early reduces the principal faster, lowering the interest charged each day.

The interest calculation resets after each on-time payment. So the total interest costs stay predictable as long as payments are not missed.

Examples of Daily Simple Interest Calculations

Here is an example to illustrate how interest accrues daily with this method:

  • Alex takes a $10,000 personal loan with 8% APR interest

  • The daily interest rate is 8% / 365 days = 0.0219%

  • On day 1, interest is $10,000 x 0.0219% = $2.19

  • On day 2, interest is $10,000 x 0.0219% = $2.19

  • Total interest for days 1-2 is $4.38

  • If Alex pays the accrued interest on day 2, the principal remains $10,000, so the interest for day 3 would again be $2.19.

In contrast, here is how much interest Alex would owe on day 2 with a compounding loan:

  • Day 1 interest: $10,000 x 0.0219% = $2.19

  • Day 2 interest: ($10,000 + $2.19 interest from day 1) x 0.0219% = $2.22

With compounding, the interest payment itself accrues more interest every day. As you can see, daily simple interest costs less over time provided payments are made on schedule.

Pros and Cons of Daily Simple Interest Loans

Daily simple interest loans have some clear benefits, along with a few potential drawbacks to keep in mind.

Pros

  • Interest costs are predictable and easy to calculate.
  • Paying on time prevents interest compounding.
  • Paying extra or early can reduce total interest costs.
  • Short-term financing costs may be lower than with compounding loans.

Cons

  • Interest accumulates daily rather than monthly, increasing costs if payments are late.
  • Harder to find than compound interest loans from mainstream lenders.
  • Long-term loans with high balances may ultimately cost more than compounding loans.
  • Prepayment penalties may apply with some lenders.

For borrowers who can pay on time consistently, the daily simple interest method provides cost control and potential savings. But for those who may struggle with payments, the daily compounding of interest can become expensive.

Types of Loans with Daily Simple Interest

Several common lending products may use daily simple interest:

  • Personal loans – Online lenders often offer personal installment loans with daily interest rather than compounding. This allows responsible borrowers to save on costs.

  • Auto loans – Many auto finance companies calculate interest daily on car loan balances. Interest decreases as the principal is paid down.

  • Home equity loans – Some home equity lenders use daily simple interest on lines of credit and fixed-rate loans. This can provide savings compared to compounded HELOCs.

  • Mortgages – Certain mortgage lenders offer daily simple interest-only loans and other specialized products. But most standard mortgages compound interest monthly.

  • Credit cards – A very small number of credit card issuers calculate interest daily rather than compounding. But this is extremely rare in the card industry.

Daily simple interest loans aren’t as widely available as compounding loans, but options exist in many lending categories if you know where to look.

How to Find the Best Daily Simple Interest Loans

Most large mainstream banks and lenders rely on compound interest. But finding daily simple interest loans is possible with a bit of research:

  • Check peer-to-peer lending marketplaces – Sites like Prosper, LendingClub, and Upstart offer fixed-rate installment loans with daily simple interest from individual investors.

  • Search online lender websites – Many online personal loan companies now disclose if they charge daily simple or compound interest. Sites like Lightstream and SoFi offer this transparency.

  • Compare community bank and credit union options – Smaller regional lenders are more likely to offer daily simple interest loan products. But availability varies, so call or check websites for details.

  • Look for auto lenders advertising “simple interest” loans – CU Direct, RoadLoans.com and other auto lenders highlight daily simple interest auto financing programs.

  • Ask mortgage brokers about specialized products – Brokers that deal with many niche lenders may know of options like daily simple interest mortgages.

Finding simple interest loans takes more effort, but the potential time savings are worth it. Evaluate whether the predictability of daily simple interest fits your borrowing needs and repayment capability.

Alternatives to Look for When Shopping for Loans

Beyond specifically seeking out daily simple interest loans, there are other features to look for when comparing loan options:

  • Fixed rates – A fixed rate ensures the interest rate won’t change, keeping payments predictable.

  • No prepayment penalties – Loans without prepayment fees allow you to pay off your balance faster without penalty, saving on interest.

  • Payoff options – The ability to make extra payments, pay weekly/biweekly, or pay ahead provides flexibility to reduce interest costs.

  • Autopay discounts – Setting up automated payments can lower your interest rate by 0.25% or more, saving on financing charges.

  • Low or no origination fees – Loans with low upfront costs preserve more of your balance for paying down principal.

While daily simple interest loans have perks, they can be hard to find. Seeking lenders that offer the above features provides alternate ways to reduce the cost of borrowing.

The Bottom Line

Daily simple interest can make loan costs more transparent and manageable. If you shop carefully and choose reliable lenders, a daily simple interest loan could potentially save money compared to compound interest alternatives.

Weigh the pros and cons carefully for your specific financial situation. And be cautious – the daily interest structure can magnify costs if you are unable to pay on time consistently. Overall, daily simple interest loans offer a consumer-friendly option to consider for certain borrowing needs and for borrowers with the means to handle payments responsibly.

Comparing Daily Simple Interest vs Fixed Interest

Daily simple interest and fixed interest are not mutually exclusive. In fact, DSI loans are usually fixed-rate loans. In other words, the interest rate does not change for the life of the loan. This is common with auto loans and short-term personal loans.

One difference you might see is with mortgages. These loans are usually calculated monthly instead of daily. As a result, paying a few days early won’t reduce how much interest you owe. That said, paying more than the minimum on the mortgage can reduce how much you owe overall.

Examples of Daily Simple Interest Loans

Two of the most common daily simple interest loans are auto loans and personal loans.

When you finance a new vehicle, the interest on that loan is often calculated using daily simple interest. For example, suppose you have a $25,000 auto loan with 6% interest and a six-year term.

On this loan, your interest for the first 30 days would be $123.29. If you paid $500 after 30 days, $376.71 goes toward the principal, bringing it to $24,623.29. After 30 more days then, the interest charge is $121.43, leading to a slightly higher principal reduction of $378.57. With each monthly payment, you reduce the principal more.

Personal loans can be used for a variety of needs; two personal loan examples are covering unex pected medical bills and paying for urgent home repairs.

While there are different types of personal loan, they often use daily simple interest. For example, if you take out a $5,000 personal loan with daily simple interest and don’t make a payment for 30 days, the loan will accrue interest for each of those 30 days. However, the principal after 30 days will still be $5,000.

On the other hand, if you made a $250 payment after 15 days, your principal would be reduced to $4,750. Then, interest would be calculated using $4,750 as the principal for the remaining 15 days that month. Hence, you would immediately reduce how much interest the loan accrues each day.

FAQ

What is a loan with daily interest?

Interest on a daily simple interest loan is calculated by using the daily simple interest method. This means that interest accrues on a daily basis on the amount of the loan (current outstanding principal balance) from the date the interest charges begin until you repay the loan.

How do you calculate daily simple interest?

Multiply your principal balance by your interest rate. Divide your answer by 365 days (366 days in a leap year) to find your daily interest accrual or your per diem. 3. Multiply this amount by the number of calendar days that have elapsed since the date of your last payment to find your interest due.

How is a simple interest loan compounded daily?

With a daily simple interest (DSI) loan, interest accrues daily but doesn’t compound. Early payments lead to less interest owed, while late payments increase your interest. DSI personal loans can seem expensive, but they’re a better alternative to more expensive forms of borrowing, such as credit cards.

What loans accrue interest daily?

Direct Loans are “daily interest” loans. On daily interest loans, interest accrues (adds up) every day. If your loans are subsidized, you are not responsible for paying the interest that accrues while you’re in school.
