Method note
Standard amortizing loans repay principal gradually over the full term. Balloon structures keep a portion unpaid until maturity. DSCR compares business income against annual debt service to assess repayment coverage.

Business loan affordability is not only about whether you can make the payment. It is also about how much cash remains after debt service, whether a balloon creates refinancing risk, and how quickly the debt reduces over time.

How this business loan calculator works

This calculator estimates the repayment structure of a business loan using the loan amount, interest rate, term, fees, and repayment type. It supports standard amortizing loans, interest-only loans with a balloon, and amortizing loans that still leave a balance due at maturity.

It also calculates coverage by comparing annual debt service against business income or NOI.

The core formulas

Periodic Rate = Annual Interest Rate ÷ Payment Frequency
Standard Payment = P × r ÷ (1 − (1 + r)^−n)
Total Interest = Total Payments − Principal Repaid
DSCR = Annual NOI ÷ Annual Debt Service
Balloon structures change the principal repayment path and leave a final payment due at maturity.

Why DSCR matters

Measure What It Shows Why It Matters
Scheduled paymentRequired payment each periodShows baseline affordability
Total interestBorrowing cost over timeShows true financing burden
Net proceedsCash actually received after feesShows funding efficiency
Balloon paymentFinal unpaid balance dueShows maturity refinancing risk
DSCRIncome coverage over debt serviceShows repayment strength and lender fit

How to read the result

A lower payment can still be risky if it comes from a large balloon balance or a much longer term. A business should evaluate not only the periodic payment, but also the total interest paid, the DSCR, and whether the maturity structure creates refinancing pressure later.

Extra payments can reduce total interest significantly, but the benefit depends on the interest rate and how early the extra cash is applied.

Frequently Asked Questions

What is a good DSCR?+
Many lenders look for at least 1.20x, and stronger cases are often 1.50x or more. The exact target varies by lender, sector, and risk profile.
What is a balloon payment?+
A balloon payment is a large final amount due at the end of the loan because the principal was not fully repaid through regular installments. It lowers periodic payments but increases maturity risk.
Should I choose interest-only to improve cash flow?+
It can reduce short-term payment pressure, but it also slows principal reduction and often leaves a large balloon. It works best when cash flow is temporarily constrained and there is a clear plan for refinance or repayment.
Do fees matter much?+
Yes. Fees reduce the actual cash the business receives and increase the effective cost of borrowing. Two loans with the same rate can still have very different economics once fees are included.
Will extra payments always help?+
In most amortizing loans, yes. Extra payments reduce the outstanding balance sooner, which lowers future interest. The impact is usually strongest when extra payments are made early in the loan.
