How does our business loan calculator work?
Our business loan calculator helps you estimate how much funding you could be eligible to borrow in a few seconds. By using average monthly interest rates and typical fees across a range of funding products, it provides an estimate of the total cost of borrowing, helping you compare your options with confidence.
If you sign up to Capitalise for Business, we'll use your Experian business credit profile and publicly available data to show the funding your business could be eligible for.

How much can my business borrow?
The amount your business can borrow depends on several factors such as how long you've been trading, your turnover and profitability, business credit score, existing debts, cash flow, and whether you can offer security. As a general guide, unsecured lenders may offer up to 25-30% of your annual turnover, while secured loans and commercial property finance can support much higher borrowing amounts. For the most accurate estimate, you can check your eligibility for funding for free with a Capitalise account.

How much does a business loan actually cost?
The cost of a business loan depends on the amount you borrow, the loan term, the interest rate, and any lender fees. Loans with longer repayment periods may have lower monthly payments, but often cost more overall.
For example, if you borrow £50,000 over 5 years at an interest rate of 8%, your monthly repayments would be around £1,014, with a total repayment of approximately £60,800. Whereas the same loan over 5 years would reduce monthly repayments to around £1,014, but increase the total repayment to approximately £60,800.
You can use our interactive business loan calculator to estimate your monthly repayments and total borrowing costs based on different scenarios.

What documents do I need to apply?
Most lenders ask for broadly the same set of documents. Having these ready before you apply makes the process faster and reduces delays.
