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
Important: Your property or assets may be repossessed if you fail to keep up repayments on a secured loan.

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

What’s the minimum and maximum I can borrow?
Secured business loans in the UK typically start at £5,000, though most lenders prefer minimums of £10,000-£25,000. The maximum varies by lender and your circumstances, but commonly extends to £500,000. Some specialist lenders offer up to £5 million for established businesses with significant assets.
How does my credit score affect the rate?
Your credit rating significantly impacts the interest rate offered. Excellent credit (score above 800) typically secures rates from 3.9-5.5%. Good credit (700-800) might see 5.5-8%. Average credit (600-700) usually means 8-12%, while poor credit (below 600) could result in rates of 12-15% or higher. However, because the loan is secured, rates are generally more favourable than unsecured alternatives regardless of credit score.
Can I repay early without penalties?
Early repayment terms vary between lenders. Many charge an early repayment fee (typically 1-5% of the outstanding balance) if you pay off the loan within the first few years. Some lenders allow penalty-free overpayments up to a certain percentage annually (often 10-20%). Always check the specific terms before signing, as early repayment charges can be substantial on large loans.
What happens if I miss a payment?
Missing payments has serious consequences. Initially, you’ll face late payment charges (typically £25-£50 per missed payment). Your credit file will be marked, making future borrowing difficult. After several missed payments, the lender may begin repossession proceedings against your secured asset. Contact your lender immediately if you’re struggling – many offer payment holidays or restructuring options.
How quickly can I get the funds?
Timescales vary depending on the security offered. Property-secured loans take longest (2-6 weeks) due to legal work and valuations. Asset-based lending against equipment or stock can be faster (1-2 weeks). Some specialist lenders offer bridging-style secured loans within 72 hours for urgent needs, though these carry higher rates.
Will taking a secured loan affect my credit rating?
Applying for the loan triggers a credit search which may temporarily lower your score by a few points. Once approved, the loan appears on your credit file. Making regular on-time payments improves your credit score over time. However, late or missed payments damage your rating significantly. The loan also affects your debt-to-income ratio, which other lenders consider.
Can I use residential property as security for a business loan?
Yes, many business owners use personal residential property as security, either through a second charge (secured loan) or by remortgaging. This can access substantial funds at competitive rates. However, you’re putting your home at risk, so ensure your business can comfortably afford the repayments even during quieter trading periods.
What’s the difference between a secured loan and a mortgage?
Both use property as security, but commercial mortgages are specifically for purchasing business premises, whilst secured loans provide cash for any business purpose. Secured loans (also called second charges) sit behind your first mortgage in priority. They typically have shorter terms than mortgages (5-15 years vs 15-25 years) and slightly higher rates.

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.

Eligibility Requirements

Whilst criteria vary between lenders, most secured business loan providers require:

Business Requirements

  • Registered UK business (Ltd company, LLP, or sole trader)
  • Trading history of at least 6-12 months (some require 2-3 years)
  • Minimum annual turnover (typically £50,000-£100,000)
  • Business bank account in company name
  • Up-to-date accounts and tax returns

Director/Proprietor Requirements

  • UK resident aged 18-75 (upper age limit varies)
  • Majority shareholder or significant control
  • Personal guarantee usually required
  • Acceptable credit history (adverse credit considered with security)

Security Requirements

  • Sufficient equity in the asset (typically 25-40% required)
  • Clear legal title to the asset
  • Professional valuation (for property)
  • Insurance in place

Documentation Needed

Prepare these documents to speed up your application:

  • Last 2-3 years’ business accounts
  • Last 6 months’ business bank statements
  • Proof of ID and address for all directors
  • Business plan (for larger amounts)
  • Details of existing business debts
  • Property deeds or asset documentation
