About the Business Loan Calculator
Business Loan Calculator helps estimate the key numbers involved in loans & debt decisions. It is designed for quick scenario comparison: enter a realistic set of values, calculate the result, then change one assumption at a time to see what has the greatest effect. Unlike a static table, the result responds to your inputs and keeps the calculation in your browser. Amounts are displayed in U.S. dollars for consistency, but the mathematical formulas can be used with another currency when every monetary input uses that same currency.
How to use this calculator
Enter values that match your situation and select Calculate result. Review the main result and its supporting figures, then change one input at a time to compare scenarios. Results are rounded for readability while the calculation retains additional precision internally.
Information you will need
- Loan amount
- Rate
- Term
How the calculation works
Standard amortization for business loans. Read the primary result together with the supporting values rather than focusing on one number alone. A useful estimate should make its assumptions visible. If the answer looks surprising, verify the unit, rate, time period, and whether the entered value is gross or net. Run a conservative and an optimistic scenario to understand the range of possible outcomes.
Formula or method
Payment = P × r(1+r)n / ((1+r)n - 1).
Worked example
$100,000 at 7% for 5 years costs about $1,980/month.
The example is illustrative rather than a recommendation. Use your own verified values and keep all monetary or measurement units consistent. When comparing alternatives, save or note each result so the assumptions do not become mixed.
How to interpret the result
The primary output answers the main question posed by the business loan calculator, while the additional cards provide context. A result with many decimal places is not necessarily more certain. The displayed precision makes comparison easier, but uncertainty in the inputs can be larger than the rounding difference.
Compare the result with a second scenario using a less favorable rate, return, cost, or time period. This sensitivity check often provides more useful planning information than one best-case projection.
Limitations and important notes
The business loan calculator is a planning tool, not a quote, filing calculation, lending decision, or promise of future performance. It does not automatically retrieve live market rates or apply every fee, tax bracket, program rule, product limit, or state law. Rules for products such as FHA, VA, Social Security, retirement accounts, and taxes can change. Confirm time-sensitive values with the lender, plan administrator, IRS, SSA, or another relevant authority before acting.
Frequently asked questions
How much can my business afford to borrow?
Lenders typically look at debt service coverage ratio (DSCR) — your net operating income divided by total debt service. A DSCR above 1.25 means you generate 25% more income than needed to cover payments. This calculator helps estimate affordable loan amounts.
What factors affect my business loan rate?
Credit score, time in business, annual revenue, industry, loan amount, and collateral all affect your rate. Established businesses with strong revenue and good credit qualify for the best rates (5-8%). Startups may pay 10-30%.
What are current SBA loan rates?
SBA loan rates are tied to the Prime rate or Treasury rates, not set by the SBA. In early 2026, with Prime at 6.75%, SBA 7(a) loans over $50,000 with terms over 7 years carry roughly Prime plus 2.25-2.75%, about 9-9.5%. SBA 504 loans price off the 5-year Treasury (around 3.88%) plus a 1.75-3.1% spread, landing near 6-7%. Rates move with the market, so your final rate depends on when you lock it in.
What is a merchant cash advance and how is it different from a loan?
A merchant cash advance (MCA) is not a loan; it is a purchase of your future receivables. Instead of fixed payments, the provider takes a percentage of daily card sales, and effective annual costs commonly run 30-80% or more. Business owners frequently describe daily MCA withdrawals as a debt trap that erodes cash flow. Refinancing an MCA into a term loan with predictable payments is a common first step to recovery. Compare the APR, not the advertised factor rate.
What is the difference between secured and unsecured business loans?
Secured loans require collateral such as real estate, equipment, inventory, or receivables, which lowers risk and rates. Unsecured loans rely only on your creditworthiness and cash flow, so they carry higher rates and stricter approval. A small business with strong revenue might get a secured rate of 6-9% versus 10-20% unsecured. The trade-off is that defaulting on a secured loan means losing the pledged asset. Many startups start unsecured, then graduate to secured lines as they build assets.
What is the SBA 7(a) program?
The SBA 7(a) program guarantees up to $5 million in loans made by approved lenders, reducing lender risk and enabling longer terms, up to 10 years for working capital and 25 years for real estate. It funds startups and small businesses that cannot get conventional financing. Expect an SBA guaranty fee of 2.25-3.5% on loans over $150,000 plus an annual servicing fee around 0.55%. Approval typically takes 30-90 days and requires a strong business plan, collateral, and a personal guarantee.
How long do I need to be in business to qualify?
Most banks want 2-3 years in business before they will consider you. SBA loans can start earlier, in many cases at startup after 10% of eligible costs are injected, and online lenders work with businesses operating just 6-12 months, though at higher rates. Revenue history, cash flow, and credit matter as much as age: a 1-year-old business with strong revenue may qualify where a 3-year-old business with thin margins will not. Prepare a 2-year cash-flow projection before applying.
