How to Use This Calculator
Getting an accurate estimate of your secured business loan costs is straightforward with our calculator. Here’s what you need to do:
Step 1: Enter Your Loan Amount
Input the amount you wish to borrow, anywhere from £5,000 to £1,000,000. Secured business loans typically range from £10,000 to £500,000, though larger amounts are available for established businesses with substantial assets. Use the slider or type directly into the field for precision.
Step 2: Set Your Interest Rate
The rate depends on several factors including your credit rating, business trading history, and the loan-to-value ratio of your security. Rates typically range from 3.9% for excellent credit to 15% for those with challenged credit histories. If you’re unsure, start with 7.5% as a middle estimate.
Step 3: Choose Your Term
Select how many years you want to repay the loan. Longer terms mean lower monthly payments but higher total interest. Most secured business loans run between 3 and 15 years, though terms up to 25 years are sometimes available.
Step 4: Add Any Fees
Include arrangement fees (typically 1-2% of the loan) and broker fees if applicable. These are often added to the loan amount, meaning you’ll pay interest on them too.
Step 5: Select Repayment Type
Capital and interest repayments gradually reduce your balance each month. Interest-only payments are lower but require you to repay the full capital at the end of the term, usually by refinancing or selling an asset.
What Are Secured Business Loans?
A secured business loan requires you to pledge an asset as collateral against the borrowed funds. This security gives lenders confidence to offer larger amounts at lower rates compared to unsecured options.
Common Types of Security
Lenders accept various assets as security for business loans:
- Commercial or residential property
- Business equipment and machinery
- Vehicle fleets
- Outstanding invoices (invoice financing)
- Stock and inventory
- Director’s personal property
Key Benefits
Secured lending offers several advantages that make it attractive for established businesses:
- Access to larger loan amounts (up to £1 million or more)
- Lower interest rates than unsecured alternatives
- Longer repayment terms for improved cash flow
- Easier approval for businesses with imperfect credit
- Potential tax benefits on interest payments
How the Calculations Work
Our calculator uses the standard amortisation formula employed by UK lenders to determine your monthly repayments.
Monthly Payment Formula
For capital and interest loans, the calculation is: M = P × [r(1 + r)^n] / [(1 + r)^n – 1]
Where M is your monthly payment, P is the principal loan amount, r is the monthly interest rate (annual rate ÷ 12), and n is the total number of monthly payments.
Total Cost Breakdown
The calculator then multiplies your monthly payment by the number of months to show total repayable amount. Subtracting the original loan gives you the total interest charged. Any fees entered are added to determine your true cost of borrowing.
APR Calculation
The Annual Percentage Rate reflects the true yearly cost including fees. It’s calculated by finding the interest rate that equates your loan amount with the present value of all future payments and charges. This lets you compare loans with different fee structures fairly.
Secured vs Unsecured Business Loans
Choosing between secured and unsecured finance depends on your circumstances and requirements. Here’s how they differ:
| Feature | Secured Loans | Unsecured Loans |
|---|---|---|
| Loan Amount | £5,000 – £1,000,000+ | £1,000 – £250,000 |
| Interest Rates | 3.9% – 15% | 6% – 30%+ |
| Repayment Terms | 1 – 25 years | 1 – 7 years |
| Collateral Required | Yes – property or assets | No |
| Approval Speed | 1 – 4 weeks | 24 hours – 1 week |
| Credit Requirements | Flexible | Stricter |
| Risk to Assets | High – may lose security | Low – personal guarantee only |
When to Choose Secured
Secured loans suit businesses that need substantial funding, want longer repayment terms, or have valuable assets but imperfect credit history. The lower rates can save thousands over the loan term.
When to Choose Unsecured
Unsecured options work better when you need funds quickly, don’t want to risk assets, or only require a smaller amount. They’re ideal for short-term cash flow needs or businesses without suitable collateral.
Frequently Asked Questions
Common Mistakes to Avoid
Borrowing More Than Needed
It’s tempting to borrow extra “just in case,” but you’ll pay interest on every pound. Calculate your exact requirements and add only a small buffer (10-15%) for contingencies. Remember, arrangement fees are also calculated on the total borrowed.
Ignoring the Total Cost
Focusing solely on monthly repayments can be misleading. A longer term reduces monthly costs but substantially increases total interest paid. For example, £100,000 at 8% over 5 years costs £20,275 in interest, but over 10 years it’s £44,652 – more than double.
Not Shopping Around
Rates and terms vary significantly between lenders. A difference of just 1% on a £200,000 loan over 10 years means £11,000 extra in interest. Use a broker or comparison service to access multiple offers, and don’t accept the first quote.
Overlooking Fees
Arrangement fees, valuation charges, legal costs, and broker fees can add £2,000-£10,000+ to your borrowing. These are often added to the loan itself, meaning you pay interest on them for the full term. Always calculate the total cost including all fees.
Choosing Interest-Only Without an Exit Plan
Interest-only repayments are much lower, but you still owe the full amount at term end. Unless you have a solid repayment strategy (property sale, business sale, refinancing), you could face difficulties when the balloon payment is due.
Not Reading the Fine Print
Pay particular attention to early repayment charges, variable rate terms, and what triggers default. Some loans have clauses allowing the lender to demand immediate repayment if your business circumstances change. Legal advice is worthwhile for large loans.
