Choosing the right calculator can speed up and improve your decision making. But with terms like ‘commercial loan calculator’ and ‘business loan calculator’ often used interchangeably, it can be confusing figuring out which tool you actually need.
Commercial loan calculators and business loan calculators may sound similar, but they exist for different reasons and are designed for different types of borrowing.
Using the wrong type of calculator could result in inaccurate estimates that aren’t aligned with what lenders will actually offer you. So it’s important to understand the differences and use the right one.
In this article, we’ll compare the main differences between commercial and business loan calculators, explain when to use each one and help you choose the right tool for your specific situation.
Key points:
Commercial loan calculators focus on property and asset-backed lending with specific loan-to-value (LTV) ratios and longer terms
Business loan calculators cover general-purpose borrowing including working capital, equipment finance and unsecured lending
Funding Options by Tide can connect you with over 120 lenders to find the right finance solution, whether you need commercial or business funding
A commercial loan calculator is specifically designed for property-backed business lending. They focus on commercial mortgages and asset-based finance where the property itself secures the loan.
Commercial loan calculators generally ask you for the value of the property you want to buy, how much you want to borrow and how much you can put towards a deposit.
This information is used to calculate your loan-to-value (LTV) ratio – usually between 60% and 75% for most commercial properties.
Commercial loan calculators are usually focused on larger loan amounts (starting from around £25,000) and longer repayment terms (e.g. 5-25 years).
The calculations should factor in commercial interest rates, which are generally lower than unsecured business lending, since your property provides the lender with security if you can’t repay the loan.
A business loan calculator can help you with a much wider range of business financing than a commercial loan calculator, such as working capital loans, equipment finance, expansion loans, and general business loans.
Business loan calculators also work with a much wider range of amounts than commercial ones, ranging from as little as £1,000 for unsecured loans and up to £100,000 or secured loans. Terms typically range from 1-10 years.
Business loan calculators are more flexible because they don’t assume you’ve got property to put up as security.
| Commercial loan calculator | Business loan calculator |
Loan amount | £25,000 to over £25 million | £1,000 to over £100,000 |
Typical terms | 5-25 years | 1-10 years |
Security | Secured with property | Secured or unsecured |
Loan-to-value ratios | 60-75% LTV | N/A |
Interest rates | Generally lower as property-backed | 4-20% APR depending on security |
Main purpose | Property acquisition or refinancing | Working capital, equipment or expansion |
Figures are averages and may vary by calculator and finance provider.
The key difference between the two calculators comes down to what you need the financing for and how the loan’s secured. Commercial calculators assume you’re using property as security, while business loan calculators can work with or without security.
The type of calculator you should use will depend on your type of business and the reason you’re looking for funding.
Commercial loan calculators can be used to research:
Buying office space, warehouses, retail premises or other commercial properties
Refinancing existing commercial property to release equity or get more competitive interest rates
Buy-to-let property investments through your business
Mixed-use properties that combine residential and commercial elements
Business loan calculators can be used to research:
Working capital to manage cash flow gaps or seasonal fluctuations
Equipment finance for machinery, vehicles, IT systems or other business assets
Expansion funding to open new locations, hire staff or enter new markets
General business loans for marketing campaigns, operational costs or buying stock
Watch out for using the wrong calculator! I may give you misleading estimates that don’t match what lenders will actually offer.
Once you’ve used a commercial or business loan calculator to get a realistic estimate, your next step depends on what you’re looking to fund.
If you’re looking to buy commercial property, you’ll typically need to gather a few documents together for your application, including business accounts, property valuations and proof of deposit. The approval process can take a few weeks, so start early if you have a deadline.
Getting a business loan can be a lot faster, particularly if you want to borrow smaller amounts or if you’re open to considering unsecured loan options. Applications can take as little as a few days rather than weeks.
Whether you need commercial or business finance, consider using a broker to simplify and speed up the process, and potentially help you access better rates. For example, Funding Options by Tide works with over 120 lenders and can match you with the most suitable options for your specific situation.

You can, but you’re unlikely to get accurate results. Business loan calculators don’t factor in loan-to-value (LTV) ratios, commercial mortgage rates or the longer terms available for property-backed lending. It’s better to use a commercial loan calculator for property-related borrowing.
Calculators can provide useful estimates. But the actual offer a lender will give you will depend on your credit history, business performance and current market conditions, amongst other things. It’s better to think of calculator results as a starting point rather than a final guarantee.
Most business lending calculators can handle both secured and unsecured loans by asking whether you’re providing security. But the terms and rates will likely be very different – secured loans typically offer lower rates and longer terms.
Commercial loan calculators can do a good job at estimating the costs of mixed-use properties. But you’ll want to consider using a broker or speaking with a lender directly for an accurate quote. Some lenders treat mixed-use properties differently, so the calculator might not accurately reflect all the options available to you.
Startups can use commercial loan calculators to get a rough idea of potential costs. But most won’t qualify for commercial mortgages without a long trading history and large deposit (typically 25-40%). For this reason, it may be worth focusing on business loan calculators until you’re more established.
