In short
An interest rate is the annual cost of borrowing, shown as a percentage of the outstanding balance. Lower rates typically favour strong credit, established time in business, and newer assets.
Lenders price a rate to match the risk of the deal. The main factors include:
The interest rate matters, but it's only part of what you pay. Term length, fees, and structure all shape the total cost of financing. A lower rate over a longer term can still cost more overall than a slightly higher rate over a shorter one. Look at the total cost, not just the headline rate, when comparing offers.
An interest rate is charged on the declining balance and expressed annually; a factor rate is a flat multiplier on the amount advanced. They aren't directly comparable without converting to a common basis.
Refinancing can lower your rate if your credit or the market has improved. Whether it saves money overall depends on the new term and any fees.
