What affects your repayments
Four things drive what a business loan costs you each month:
- Amount borrowed — the larger the loan, the larger the repayment, all else being equal.
- Term — a longer term spreads the cost into smaller monthly payments but means you pay interest for longer, raising the total interest.
- Interest rate — the single biggest lever on cost. Rates depend on the lender, the type of finance and how they price risk.
- Security — a loan secured against assets or property usually carries a lower rate than an unsecured one, because the lender has less risk.
- Credit profile and trading history — an established business with strong accounts and a clean credit history will typically be offered keener rates than a newer or higher-risk borrower.
Types of business finance you can compare
This calculator models a standard term loan, but it is not the only way to fund a business. Depending on what you need, you might compare:
- Business loans — compare the whole market in a single enquiry.
- Unsecured business loans — a lump sum with no assets put at risk.
- Merchant cash advance — repay as a percentage of your card takings rather than a fixed monthly sum.
- Growth Guarantee Scheme — government-backed funding for viable UK businesses.
It takes under a minute — and enquiring never affects your credit score.
Frequently asked questions
What is the monthly payment on a £50,000 business loan?
At a representative rate of 9.9% APR, a £50,000 business loan repaid over 36 months works out at around £1,611.01 a month, repaying roughly £57,996 in total. Shorter terms mean higher monthly payments but less interest overall: over 12 months it is about £4,393.47 a month, while over 60 months it falls to around £1,059.89. Your actual rate and payment depend on your business, the lender and the loan term.
How is a business loan repayment calculated?
Most business loans use a standard amortising formula: M = P · r · (1 + r)ⁿ ÷ ((1 + r)ⁿ − 1), where P is the amount borrowed, r is the monthly interest rate (the annual rate divided by 12) and n is the number of monthly payments. Each repayment covers the interest due that month plus a slice of the capital, so the balance falls to zero by the end of the term. Our calculator applies exactly this formula to give you an instant estimate.
What interest rate will I pay on a business loan?
Business loan rates in the UK vary widely — typically from around 6% to 20%+ APR — depending on how much you borrow, the term, whether the loan is secured, your trading history and your credit profile. Stronger, established businesses with security generally access the lowest rates. The 9.9% used as a default here is only a representative example; the calculator lets you enter your own expected rate to model different scenarios.
Does using the calculator affect my credit score?
No. The calculator is purely an illustration that runs in your browser — it involves no credit check and leaves no trace on your credit file. Even when you enquire with us for real quotes, the initial check is a soft search that does not affect your credit score. Only if you proceed to a formal application with a lender might a hard credit check be carried out, and you would be told before that happens.
