Small Business Loan Affordability Calculator
Small-business loan size is constrained by cash flow as much as collateral. This calculator converts EBITDA and target DSCR into estimated affordable loan proceeds.
Estimated affordable loan
$1,304,811
Available annual debt service
$264,000
Max monthly payment
$22,000
Cash flow cushion at target
$84,000
How the math works
Available annual debt service equals EBITDA divided by target DSCR, minus existing annual debt payments. That available payment is converted into loan proceeds using the APR and term.
Use conservative EBITDA when revenue is seasonal, customer concentration is high, or working-capital swings consume cash.
EveryCalc calculators are designed for fast, practical estimates with transparent inputs and no required account. We use plain formulas, visible assumptions, and related tools so visitors can check the result from more than one angle.
Results are informational only. For financial, tax, legal, medical, construction, or other high-impact decisions, verify the output against primary sources or a qualified professional.

How this calculator works
What this page estimates
This Small Business Loan Affordability Calculator is built to give a quick, browser-based estimate for small business loan affordability. Small-business loan size is constrained by cash flow as much as collateral. This calculator converts EBITDA and target DSCR into estimated affordable loan proceeds. The inputs stay on the page during normal use, and the result should be treated as an estimate for planning, comparison, or education rather than professional advice.
Calculation approach
The calculator applies the standard relationship implied by the inputs, then formats the answer so it can be checked and reused. For finance tools, the most important step is using consistent units, rates, time periods, and assumptions before comparing the result with another calculator or outside quote.
Example workflow
For example, start with a realistic value you already know, change one input at a time, and watch how the answer moves. That makes it easier to tell whether the result is being driven by the main amount, the rate, the time period, or a unit conversion.
Practical checks
- Use current, real-world numbers when the result affects money, health, tax, or legal decisions.
- Run a low, base, and high case when the inputs are estimates.
- Check the related calculators below when the next decision depends on a different assumption.
How to interpret the small business loan affordability result
Best use
Use the result as a planning number for comparing payments, rates, returns, tax reserves, or cash-flow choices before you request a quote or make a commitment.
Cross-check
Compare the answer with the contract, lender estimate, tax form, brokerage statement, payroll record, or invoice that will control the real-world outcome.
Watch for
Do not rely on a single optimistic rate, return, or fee assumption. Money pages work best when you run low, base, and high cases and keep professional advice separate from the estimate.
This page belongs to the Finance calculator library, so the answer should be read in the context of the decision you are modeling rather than as a universal rule.
Before relying on this small business loan affordability estimate
Most calculator mistakes come from the inputs, not the arithmetic. Use this short audit before you reuse the answer in a spreadsheet, quote, application, or important conversation.
Confirm source numbers
Match balances, rates, fees, taxes, income, and payment dates against the lender quote, payroll record, tax form, statement, invoice, or contract.
Separate cash flow from total cost
A lower monthly payment can still cost more over time if fees, interest, taxes, or a longer term are hidden in the structure.
Run conservative cases
Test at least one higher-cost or lower-return case before using the output for a purchase, refinance, investment, loan, or tax decision.
Rerun this page when the rate, price, term, fee, tax rule, income, expense, or expected holding period changes.
How to Use
- Enter annual EBITDA or cash flow available for debt service.
- Subtract existing annual debt service.
- Choose a target DSCR, APR, and term.
- Review maximum annual payment and estimated loan amount.
Frequently Asked Questions
What DSCR should I use?
Many lenders want cash flow comfortably above required debt service. A higher target DSCR produces a more conservative maximum loan amount.
Does this approve a loan?
No. It estimates affordability only. Lenders also review credit, collateral, industry risk, tax returns, leverage, liquidity, and documentation.
Why use EBITDA?
EBITDA is a common starting point for debt capacity, but owner add-backs, taxes, capex, and working capital can change true cash flow.
