Things to Know

Essential concepts for understanding your results

Loan Types
What types of business loans are available?

Term loans: lump sum repaid over 1-25 years — best for equipment, expansion, or one-time investments. Lines of credit: revolving access to funds — best for cash flow gaps and seasonal needs. SBA loans: government-backed with lower rates and longer terms — best value but slower approval. Equipment financing: the equipment itself serves as collateral — easier approval. Invoice factoring: sell unpaid invoices for immediate cash — expensive but fast. Choose based on purpose, timeline, and how quickly you need funds.

Qualification
What do business lenders look for?

Five key factors: credit score (680+ for best rates, 600+ minimum for many lenders), time in business (2+ years preferred, startups need stronger personal credit), annual revenue (minimum $100K-250K for most term loans), debt service coverage ratio (DSCR above 1.25), and collateral (business assets, equipment, or personal guarantee). Strengthening any one factor can compensate for weakness in another.

True Cost
How do you calculate the true cost of a business loan?

Compare using total cost of capital, not just interest rate. A $100,000 loan at 8% with 2% origination fee for 5 years: total interest $21,660 + fee $2,000 = $23,660 total cost. APR captures this: approximately 8.8%. Factor in any prepayment penalties, monthly fees, and required minimum balances. Online lenders may show weekly payments that appear low but annualize to 15-25% APR — always convert to annual terms for comparison.

Business Loan Calculator: Estimate Your Monthly Payment and Total Cost

A business loan calculator computes the monthly payment, total interest, and payoff schedule for term loans, SBA loans, and lines of credit used to fund business operations, equipment, real estate, or expansion. Business lending is a $800+ billion annual market (Federal Reserve SLOOS data), with rates and terms varying dramatically by loan type, lender, and business strength.

Enter your loan amount, interest rate, term, and any fees above. The calculator shows monthly payments, total cost, and amortization schedule with comparison across different term lengths.

The Federal Reserve's Small Business Credit Survey (2024) shows that 47% of small businesses applied for financing in the past year. Approval rates: large banks 43%, small banks 75%, online lenders 66%. The approval gap explains why SBA loans are so popular — the government guarantee enables bank approvals that would otherwise be declined. See our SBA Loan Calculator for SBA-specific analysis.

Frequently Asked Questions

What is the average business loan rate?
Bank term loans: 7-12%. SBA 7(a): 9.75-12.25% (Prime + margin). SBA 504: 6-7% fixed. Online lenders: 10-60%+ (wide range based on risk). Equipment financing: 6-15%. Your rate depends primarily on: business revenue and profitability, time in business (2+ years preferred), personal credit (680+ for best rates), and collateral available.
How much business loan can I qualify for?
General guideline: lenders approve loans up to 10-15% of annual revenue for unsecured, or up to 80-90% of collateral value for secured loans. SBA 7(a): up to $5 million. SBA 504: up to $5.5 million. A business with $500,000 revenue might qualify for $50,000-$75,000 unsecured or $200,000+ with real estate collateral. DSCR (debt service coverage ratio) of 1.25+ is typically required.
Should I avoid merchant cash advances?
In almost all cases: yes. MCAs have effective APRs of 20-150%+ and aggressive daily repayment terms that can cripple cash flow. They are designed for speed and easy qualification — not borrower benefit. Explore every alternative first: SBA microloans, credit union loans, business credit cards (0% intro), or even personal loans (7-15%) before considering an MCA. The convenience of fast funding is not worth 5-15x the cost.
How long does it take to get a business loan?
Online lenders: 1-7 days. Bank term loan: 2-6 weeks. SBA 7(a): 2-3 months. SBA 504: 2-4 months. SBA Express: 36 hours for SBA approval. Speed and rate are inversely correlated — the fastest loans are the most expensive. If timing allows, apply 3-4 months before you need funds and pursue the slower, cheaper SBA or bank options.
Do I need a personal guarantee for a business loan?
Almost always — for small businesses. SBA loans require personal guarantees from anyone owning 20%+ of the business. Bank loans for small businesses nearly always require a personal guarantee. Only very large businesses ($10M+ revenue) with strong balance sheets can access non-recourse business loans. The personal guarantee means your personal assets (home, savings) are at risk if the business cannot repay — understand this before signing.
