Understanding your business loan calculator results

Your calculator results show three key figures that determine whether a business loan works for your budget: <br></br> <br></br> <li><b>Monthly payments:</b> This is the total amount you’ll need to repay each month, including both the principal (the original loan amount borrowed) and interest.</li> <li><b>Monthly interest:</b> This is the portion of your monthly payment that goes toward interest charges. In the early months of your loan, a larger portion goes to interest, while later payments focus more on reducing the principal balance.</li> <li><b>Total interest:</b> This is the total amount of interest you’ll pay over the duration of the loan. Even a 1-2% difference in interest rates can save you thousands on larger loans!</li> <li><b>Length of loan:</b> This is the total number of months that you’ll repay the loan over. Longer-term lengths should mean lower monthly payments, but they’ll also typically result in higher total interest.</li> <li><b>Total cost of loan:</b> This is the total amount you’ll pay over the duration of the loan, including the initial principal amount and total interest.</li> <br></br> <br></br> Your calculator results can help you answer the question, “How much will my business loan cost?” And it’ll help ensure you’re making a decision based on complete information, not just the headline interest rate. <br></br> <br></br> <b>Tip:</b> Focus on both monthly affordability (can your cash flow handle the payments?) and total cost (is the overall expense justified by your business needs?) A suitable loan should balance both manageable monthly payments and reasonable total costs.
