How to use this calculator
This calculator uses standard principal-and-interest amortisation — the same formula banks use. Adjust the four inputs to model different borrowing scenarios:
- Loan amount: How much you want to borrow ($5,000 to $350,000). Use the slider for any size, or pick a preset for common amounts ($5K, $25K, $50K, $100K, $200K, $350K).
- Loan term: How long you want to repay (3, 6, 12, 18, or 24 months). Shorter terms mean higher monthly payments but less total interest. Longer terms reduce the monthly burden in exchange for higher overall borrowing cost.
- Interest rate: The cost of borrowing applied to the declining balance. Banks for established businesses quote 6%–10%; non-bank unsecured loans typically range from 12%–25%.
- Origination fee: The upfront fee charged by the lender, typically 0–5% of the loan amount. Including this gives the true total cost of borrowing.
The results update instantly as you move the sliders. Compare multiple scenarios to understand how term length and rate affect your total cost — then check your eligibility across 30+ lenders to see real offers.

The monthly repayment is only part of the picture. When comparing business loans, pay attention to these cost factors:
- Origination / establishment fees: Many lenders charge 1–3% of the loan amount as an upfront fee. Include this in the calculator so the Total Repayable figure reflects what you actually owe.
- Monthly account fees: Some products carry a recurring administration fee of $10–$30/month.
- Early repayment penalties: Some lenders charge a fee if you pay out the loan early. Others allow fee-free early repayment — confirm this before signing.
- Headline rate vs total dollar cost: Two loans with similar headline rates can differ by thousands of dollars in total cost once fees and term length are taken into account. Always compare the total dollar amount you will repay, not just the rate. Read our guide to getting a business loan in Australia for a full breakdown of what lenders look for.

Frequently asked questions
Calculator examples by loan amount
Common Australian business loan amounts and their typical monthly repayments. Each example assumes 15% interest (a representative non-bank unsecured rate) over a 24-month term with a 2% origination fee. Adjust the calculator above to model your specific scenario.
$50,000 Business Loan Calculator
A $50,000 unsecured business loan at 15% interest over 24 months costs approximately $2,425/month, with total interest of around $8,200 and a $1,000 origination fee — total repayable of roughly $59,200. This amount commonly funds working capital, marketing campaigns, or smaller equipment purchases. Many cafe owners use this band for espresso machine upgrades and small fit-outs. See cafe and restaurant loans for sector-specific guidance.
$100,000 Business Loan Calculator
A $100,000 unsecured business loan at 15% interest over 24 months costs approximately $4,850/month, with total interest of around $16,400 and a $2,000 origination fee — total repayable of roughly $118,400. This is the most common borrowing band for Australian small businesses and typically funds hiring, expansion, or partial fit-outs.
$150,000 Business Loan Calculator
A $150,000 unsecured business loan at 15% interest over 24 months costs approximately $7,275/month, with total interest of around $24,600 and a $3,000 origination fee — total repayable of roughly $177,600. At this amount, secured options (chattel mortgage or equipment finance) often become more cost-effective if you have qualifying assets — see equipment finance for comparison.
$200,000 Business Loan Calculator
A $200,000 unsecured business loan at 15% interest over 24 months costs approximately $9,700/month, with total interest of around $32,800 and a $4,000 origination fee — total repayable of roughly $236,800. This band often funds full hospitality fit-outs, larger commercial vehicles, or acquisition-related working capital.
$300,000 Business Loan Calculator
A $300,000 unsecured business loan at 15% interest over 24 months costs approximately $14,550/month, with total interest of around $49,200 and a $6,000 origination fee — total repayable of roughly $355,200. At this amount, lenders typically require stronger trading history (12+ months) and higher monthly revenue (typically $50,000+).
$500,000 Business Loan Calculator
A $500,000 business loan typically moves into secured territory for most borrowers. Unsecured at 15% over 24 months would be roughly $24,250/month with total interest near $82,000 — but at this level, a secured product (chattel mortgage, property-secured business loan, or commercial bill) at 8-10% would more commonly cost $22,640/month with substantially less total interest. Larger loans warrant careful comparison across both secured and unsecured options.
$1,000,000 Business Loan Calculator
A $1 million business loan is generally a secured commercial facility rather than an unsecured product. At 8% interest over 60 months, repayments are approximately $20,275/month with total interest near $216,500. Loans of this size typically require property security, audited financial statements, and 24+ months of trading history. Most non-bank unsecured lenders cap at $350,000–$500,000.
All figures are indicative and based on standard principal-and-interest amortisation. Actual lender quotes vary based on your business profile, security, and term length.

How business loan repayment formulas work
Business loan calculators — including ours — use the standard principal-and-interest amortisation formula. Each monthly payment covers a portion of the principal plus interest on the outstanding balance. Early in the loan, most of each payment goes toward interest; by the end, most goes toward principal. As you pay down the principal, the interest portion of each payment shrinks because interest is charged on the declining balance.
The formula for the monthly repayment on a fully amortising loan is: M = P × r × (1 + r)n ÷ ((1 + r)n − 1), where M is the monthly repayment, P is the principal, r is the monthly interest rate (yearly rate ÷ 12), and n is the number of monthly payments. The calculator does this maths for you — adjust the sliders and the results update instantly.
Beyond the headline rate, watch for origination fees (1–3% of the loan amount), monthly account fees ($10–$30), and early repayment penalties. Two loans with the same advertised rate can differ by thousands of dollars in total cost once fees are taken into account. Always calculate the total cost of borrowing — not just the monthly payment — before committing.
