Introduction
A business loan is one of the most common ways to fund growth, buy equipment, or cover day-to-day costs. But before you sign on the dotted line, you need to know exactly what that loan will cost you each month and over its full term. Our Business Loan Calculator works out that math for you. Just enter your loan amount, interest rate, and repayment term, and you'll get a clear breakdown of your payment amount, total interest, total cost, and effective APR.
This calculator goes beyond basic payment estimates. It lets you factor in origination fees, documentation fees, and other closing costs so you can see the true cost of borrowing. You can also choose from multiple compounding and payment frequencies (monthly, biweekly, quarterly, interest-only, or even lump sum at maturity) to match the exact loan structure you're considering.
One of the most useful features is the built-in loan qualification assessment. By entering your annual revenue, net operating income, and existing monthly debt payments, the calculator computes your Debt Service Coverage Ratio (DSCR) and debt-to-income ratio. These are the same metrics lenders use to decide whether to approve your loan. A DSCR of 1.25x or higher generally means you're in good shape. Below 1.0x, and most lenders will turn you down. This tool tells you where you stand before you even apply.
You'll also get a full amortization schedule showing how each payment splits between principal and interest, along with interactive charts that display your remaining balance and cumulative interest over time. This calculator gives you the numbers you need to make a smart borrowing decision.
How to Use Our Business Loan Calculator
Enter your loan details and business income below to see your payment amount, total cost, interest paid, effective APR, and whether you are likely to qualify for the loan.
Loan Amount: Type in the total dollar amount you want to borrow. You can also drag the slider to pick a value between $0 and $2,000,000.
Interest Rate: Enter the yearly interest rate on the loan as a percentage. Use the slider or type a number directly to set rates from 0% to 25%.
Amortization Period: Set how long you have to pay back the loan by entering the number of years and months. The total must be at least one month.
Compounding Frequency: Choose how often interest is compounded. Options range from annually to daily, and also include continuous compounding. Monthly (APR) is the most common for business loans.
Payment Frequency: Pick how often you make payments. You can choose daily, weekly, biweekly, semi-monthly, monthly, quarterly, semi-annual, or annual payments. You can also select interest-only payments or a single lump sum due at the end of the loan term.
Origination Fee: Enter the upfront origination fee as a percentage of the loan amount. This fee is charged by the lender when the loan is issued.
Documentation Fee: Enter any flat dollar amount the lender charges for processing and paperwork.
Other Fees: Enter any other flat fees tied to the loan, such as appraisal or filing costs.
Annual Gross Revenue: Enter your total yearly business revenue before any expenses are taken out. Lenders use this to measure your debt-to-income ratio.
Annual Net Operating Income: Enter your yearly net operating income, also known as EBITDA or NOI. This is your revenue minus operating expenses, and it is the key number lenders use to calculate your Debt Service Coverage Ratio (DSCR).
Monthly Obligations (Existing Debt): List each existing monthly debt payment your business already owes, such as current loans, leases, or credit lines. Use the "Add Obligation" button to include more debts. The calculator adds these to your new loan payment to check if your income can cover all debt.
Business Loan Calculator
A business loan is money you borrow from a bank, credit union, or online lender to fund your company's needs. Business owners use loans to cover things like buying equipment, hiring staff, managing cash flow, expanding to a new location, or purchasing inventory. Unlike personal loans, business loans are based on your company's financial health, including its revenue, net operating income, and existing debt.
How Business Loan Payments Work
Most business loans use a process called amortization. This means each payment you make is split into two parts: one part pays down the principal (the original amount you borrowed), and the other part covers the interest (the fee the lender charges for letting you use their money). Early in the loan, a bigger chunk of your payment goes toward interest. As time goes on, more of each payment goes toward the principal, and the balance shrinks faster. You can explore this principal-versus-interest breakdown in detail with our Amortization Calculator.
Key Terms to Understand
The interest rate is the yearly percentage the lender charges on your remaining balance. The amortization period (or loan term) is the total length of time you have to repay the loan. Compounding frequency describes how often interest is calculated on your balance. Monthly compounding (APR) is the most common, but some loans compound daily, quarterly, or even continuously. A higher compounding frequency means you pay slightly more interest over the life of the loan.
Payment frequency is how often you make payments. Monthly is standard, but some lenders offer weekly, biweekly, or even daily payments. Two special options are interest-only, where you pay just the interest each period and owe the full principal at the end, and lump sum at maturity, where you make no regular payments and pay everything (principal plus all accumulated interest) in one payment when the loan ends. Both of these result in a large balloon payment at the end of the term.
Fees and the True Cost of Borrowing
The interest rate alone doesn't tell you the full cost of a loan. Most business loans come with fees. An origination fee is a percentage of the loan amount the lender charges upfront for processing the loan. Documentation fees and other closing costs add to this. When you factor all fees into the cost, you get the effective APR (Annual Percentage Rate), which is always equal to or higher than the stated interest rate. The effective APR gives you a more honest picture of what the loan actually costs and makes it easier to compare offers from different lenders. Our APR Calculator can help you compare effective rates side by side.
How Lenders Decide If You Qualify
Lenders look at specific numbers to decide whether your business can handle a loan. The two most important are:
- DSCR (Debt Service Coverage Ratio): This compares your net operating income to your total annual debt payments, including the new loan. A DSCR of 1.0 means your income exactly covers your debt, with nothing left over. Most lenders want to see a DSCR of 1.25x or higher, meaning your income is at least 25% more than your total debt payments. This gives them confidence you can repay even if revenue dips. Use our DSCR Calculator for a focused analysis of this ratio.
- Debt-to-Income Ratio (DTI): This shows your total annual debt payments as a percentage of your gross revenue. A lower DTI means less of your revenue is tied up in debt, which lenders view favorably.
Tips for Getting the Best Business Loan
Shop around and compare the effective APR, not just the interest rate, across multiple lenders. Choose the shortest loan term you can comfortably afford, since shorter terms mean less total interest paid. Watch out for high origination fees, which can add thousands of dollars to your cost. If your DSCR is below 1.25x, consider paying down existing debt or increasing revenue before applying. Finally, always review the full amortization schedule so you know exactly how much of each payment goes to principal versus interest and when your loan will be fully paid off.
