When you're evaluating equipment financing offers, terms like simple interest, rate, and APR get thrown around a lot. And if you've ever walked away from a loan agreement wondering what did I actually pay in interest?—you’re not alone.
In my experience the rate is just one factor and no matter how it is presented the most important thing to understand are the loan terms including the rate, fees, and prepayment options. I'll cover those in a later section.
For now, Understanding the three most common ways interest is presented is a great place to start.
What is Simple Interest?
Simple interest refers to the basic cost of borrowing money without compounding. It’s calculated using a formula:
(Monthly Payment × Term in Months – Equipment Cost) ÷ Term in Years ÷ Equipment Cost
Example: You're financing a $100,000 piece of equipment for 5 years (60 months) at 9.99% interest (not APR)
$2,124.21 (monthly payment) x 60 (term in months) = $127,452.60
$127,452.60 (total of payments) - $100,000 (equipment cost) = $27,452.60 (total interest)
$27,452.60 (total interest) ÷ 5 (term in years) = $5,490.52 (annual cost of funds)
$5,490.52 (annual cost of funds) ÷ $100,000 (equipment cost) = 5.49% (simple interest rate)
This gives you a rough idea of how much interest you're paying over time, spread out annually, but it doesn't reflect amortization or fees.
What Is the "Rate"?
The "rate" can mean a few things, but ultimately it is the percentage that you're being charged, but it doesn't reflect fees. It might look like:
"your rate is 9.99%"
But this figure is not necessarily an APR and doesn't have to includes other costs like documentation fees, origination charges, or prepayment penalties. It's best used as a basic comparison tool, but it's not the full picture.
This can be double checked by plugging the terms you were told into basically any online calculator. I typically use Bankrate's calculator tool, but there are plenty out there.
What Is APR?
APR (Annual Percentage Rate) is the most standardized way to understand the true cost of borrowing. It includes:
Interest
Fees
Any additional costs rolled into the loan
This makes APR the most whole metric when comparing financing offers side-by-side, but in the alternative lending space companies aren't always able to quote an APR.
Why This Matters in Equipment Financing
In equipment finance, especially for small businesses, comparing offers can be confusing. Lenders may advertise low rates, but backload fees or use precomputed interest methods that favor the lender.
Make sure to:
Review payments and terms side by side when comparing
Read any agreements you are provided.
Understand prepayment terms—some loans penalize early payoffs
Understand any upfront fees
Bottom Line
If you're considering equipment financing, it pays to ask the right questions. Don’t settle for vague numbers or confusing sales pitches.
