UNDERSTANDING LOAN COST

How much does a loan really cost?

The amount you borrow is not necessarily the amount you will repay. Interest adds to the cost of borrowing over the life of the loan.

This calculator estimates total interest by calculating the scheduled monthly payment and multiplying it by the number of payments in the selected loan term.

The result gives you a simple way to see the relationship between the original loan amount, interest cost, and total repayment.

This can be particularly useful when comparing different interest rates or repayment periods.

Why the loan term matters

A longer repayment period can reduce the scheduled monthly payment because the balance is spread across more payments.

However, keeping a balance outstanding for a longer period can increase the total amount of interest paid.

Comparing both the monthly payment and total interest gives you a clearer view of the tradeoff between payment size and total borrowing cost.

Business financing considerations

For a business, financing costs should be considered alongside revenue, operating expenses, existing debt, and available cash flow.

A loan that appears affordable based only on the monthly payment may have a different impact when viewed alongside the company's complete financial picture.

Actual financing terms can also include fees, variable rates, different repayment structures, or other costs that are not included in this basic estimate.

COMPARE YOUR OPTIONS

The lowest monthly payment is not always the lowest total cost

When comparing loans, look at more than the monthly payment. Interest rate, repayment period, and total interest can all change the amount you ultimately repay.

MONTHLY PAYMENT

What will you pay each month?

Use the payment amount to understand the recurring cash requirement.

TOTAL INTEREST

What does borrowing cost?

See the estimated interest accumulated over the repayment period.

TOTAL REPAYMENT

How much goes back to the lender?

Compare the original principal with the total amount repaid.

ADVANCED FINANCE ANALYSIS

Loan cost is only one part of the financing decision.

Once you understand total repayment, you can compare financing structures, test affordability, evaluate debt capacity, and model how financing could affect your business cash flow.
