Business Loan Calculator

A business loan offer is rarely just a principal, a rate, and a term. Fees may be paid in cash, subtracted from the disbursement, or rolled into the balance that accrues interest. Payment schedules can be monthly, weekly, bi-weekly, or quarterly. The Business Loan Calculator is built for that commercial-loan reality: it estimates the periodic payment, the cash your business receives, the amount that is actually amortized, total interest, total payments, total finance charge, APR including fees, and effective APR.

Use this page when you are comparing working-capital loans, equipment financing, startup funding, a fixed-rate SBA-style term loan, or any lender quote that mixes interest with origination and closing costs. For a simpler consumer installment loan, use the loan calculator. If the borrowing is for real estate, compare the result with the mortgage calculator. If the payment needs to fit a wider operating plan, pair it with the budget calculator and the compound interest calculator for opportunity cost comparisons.

How to use the business loan calculator

Enter the lender’s loan amount first. This is the face amount stated in the offer before fee treatment. Add the nominal interest rate, the loan term, and the compounding frequency. Compounding determines how the annual rate is converted into an effective annual rate; the calculator then converts that into the payment-period rate for the selected payment frequency.

Next, enter fees in the way the lender actually charges them. A prepaid fee is paid at closing and is not added to the debt balance. A loaned fee is rolled into the amount that accrues interest. The origination fee is entered as a percentage of the stated loan amount, then you choose whether it is deducted from proceeds, financed into the balance, or paid upfront. This distinction is important: the payment may be based on one amount, while the usable cash your business receives may be lower.

Formula used by the calculator

The calculator first finds the origination fee and the balance to amortize:

origination fee=loan amount×origination percentage100\text{origination fee} = \text{loan amount} \times \frac{\text{origination percentage}}{100}

P=loan amount+loaned fee+financed origination feeP = \text{loan amount} + \text{loaned fee} + \text{financed origination fee}

It converts the nominal annual rate into an effective annual rate using the selected compounding frequency:

effective annual rate=(1+nominal ratecompoundings per year)compoundings per year−1\text{effective annual rate} = \left(1 + \frac{\text{nominal rate}}{\text{compoundings per year}}\right)^{\text{compoundings per year}} - 1

Then it converts the effective annual rate into the payment-period rate:

r=(1+effective annual rate)1payments per year−1r = \left(1 + \text{effective annual rate}\right)^{\frac{1}{\text{payments per year}}} - 1

With P as the amount amortized, r as the payment-period rate, and n as the rounded number of payments, the payment is:

payment=P×r1−(1+r)−n\text{payment} = \frac{P \times r}{1 - (1 + r)^{-n}}

The total finance charge includes interest plus all fee categories:

finance charge=interest paid+prepaid fees+loaned fees+origination fee\text{finance charge} = \text{interest paid} + \text{prepaid fees} + \text{loaned fees} + \text{origination fee}

APR is estimated by solving for the periodic rate that makes the payment stream equal to the net proceeds received, then multiplying by payments per year. Effective APR compounds that solved periodic APR for a year.

Example

Suppose your business is offered a $100,000 loan for 5 years at an 8% nominal annual rate, compounded monthly and paid monthly. The lender also charges a $1,000 prepaid fee, a $2,000 loaned fee, and an 8% origination fee that is deducted from proceeds.

The origination fee is $8,000. Because it is deducted rather than financed, the amount amortized is the $100,000 loan amount plus the $2,000 loaned fee, or $102,000. The cash received is lower: $100,000 minus $1,000 prepaid fee minus $8,000 deducted origination fee, or $91,000. There are 60 monthly payments.

Using the formula above, the monthly payment is $2,068.19. Total payments are $124,091.53. Total interest is $22,091.53 because the payment stream repays $102,000 of amortized principal. Total fees are $11,000, so the total finance charge is $33,091.53. Solving APR against the $91,000 received gives an APR of about 12.95% and an effective APR of about 13.75%. This is why a low-looking nominal rate can still be expensive when significant fees reduce proceeds.

How to read the result

Start with the periodic payment, but do not stop there. The You receive line shows whether the loan actually provides enough cash for payroll, inventory, equipment, or expansion. The Amount amortized line shows what balance drives the payment. If that number is much higher than the cash received, the fee structure is doing real work. The Total finance charge is the broadest dollar cost because it includes interest and fees. APR and effective APR convert that cost into annualized percentages for offer comparison.

For businesses, affordability should be judged against cash flow, not only against profit. A seasonal retailer may prefer a higher total cost if the payment frequency matches receivables. A contractor might value lower upfront cash needs even if financed fees raise interest. A borrower with thin margins should test a shorter term, lower amount, or larger down payment before accepting a payment that leaves no room for taxes, rent, insurance, inventory, or delayed customer payments.

Tips for comparing business loan offers

  • Compare offers using the same loan amount, term, compounding, and payment frequency before changing one variable at a time.
  • Ask the lender to separate prepaid, deducted, financed, guarantee, packaging, and servicing fees.
  • Watch payment frequency. Weekly payments can create more cash-flow pressure than monthly payments even when the total cost looks similar.
  • Confirm whether the rate is fixed or variable, and whether compounding changes if the loan reprices.
  • Review collateral, personal guarantees, covenants, reporting obligations, and prepayment penalties alongside the numerical payment.
  • Keep enough working capital after closing. A loan that fully funds a purchase but starves operations can be more dangerous than a smaller loan paired with a slower rollout.

Frequently asked questions

How is this business loan calculator different from a basic loan calculator?
A basic loan calculator usually uses only principal, rate, and term. This page also models business borrowing costs such as prepaid fees, loaned fees, origination fees, compounding frequency, payment frequency, net proceeds, finance charge, APR, and effective APR, so offers with the same headline rate can be compared more realistically.
What does the amount amortized mean?
Amount amortized is the balance the payment is calculated on. In this calculator it equals the stated loan amount plus loaned fees and any origination fee you choose to finance. Fees paid upfront or deducted from proceeds do not increase that payment balance, but they still affect the cash received and APR.
Why can APR be higher than the nominal interest rate?
APR includes the cost of required fees and the timing of cash flows. If an origination fee is deducted from proceeds, you receive less usable cash but still repay the scheduled loan balance. That smaller net benefit makes the annualized borrowing cost higher than the nominal interest rate shown on the note.
Should I choose deducted, financed, or upfront origination fees?
The right comparison depends on cash flow. Deducted and upfront fees reduce cash available at closing, while financed fees raise the balance and usually the payment. Use the same loan amount, term, and rate for each option, then compare net proceeds, total finance charge, APR, and effective APR.
