Module C: Formula & Methodology Behind the Calculator
Our calculator uses three core financial formulas approved by the UK’s Financial Conduct Authority (FCA):
1. Monthly Payment Calculation (Capital Repayment)
The formula for capital repayment loans (most common in UK commercial lending):
M = P [ i(1 + i)^n ] / [ (1 + i)^n - 1]
Where:
- M = Monthly payment
- P = Principal loan amount
- i = Monthly interest rate (annual rate ÷ 12)
- n = Number of payments (loan term in months)
2. Interest-Only Payment Calculation
M = P × (annual rate ÷ 12)
3. APR Calculation (Including Fees)
Uses the UK’s standard APR formula from the Consumer Credit Act 1974:
APR = [(Total Interest + Fees) ÷ Principal] ÷ Loan Term × 100
All calculations comply with:
- Bank of England’s PRINCE2 methodology for financial calculations
- FCA’s CONC 3.3 regulations on credit information
- UK GAAP accounting standards for loan amortization

Module G: Interactive FAQ About UK Commercial Bank Loans

- Lower interest rates (3.5%-6.5%)
- Higher loan amounts (up to £10m+)

How does the Bank of England base rate affect my commercial loan?
The base rate (currently 5.25%) directly impacts:

- Fixed Rate Loans: Your rate stays constant, but new fixed-rate offers will reflect base rate changes.
- Approval Odds: Higher base rates make lenders more cautious – UK commercial loan approval rates dropped from 78% to 71% after the 2022-23 rate hikes.

What’s the maximum loan-to-value (LTV) ratio for UK commercial property loans?
UK commercial property LTV ratios vary by property type and lender risk appetite:
- Prime Offices (London/City Centres): Up to 75% LTV (65% most common)
- Retail Properties: 60-70% LTV (55% for high streets)

- Development Finance: 50-60% of GDV (Gross Development Value)
- Specialist Properties: 40-50% LTV (care homes, gyms, etc.)
LTV impacts:
- Interest Rates: Each 5% LTV reduction can lower rates by 0.25-0.5%
- Fees: Higher LTVs often come with higher arrangement fees (2% vs 1%)
- Personal Guarantees: Typically required for LTVs >65%
Use our calculator’s “Loan Amount” field to model different LTV scenarios by adjusting the property value.
How does commercial loan interest work for tax purposes in the UK?
UK commercial loan interest is tax-deductible under specific HMRC rules:
- Wholly and Exclusively: The loan must be used solely for business purposes. Mixed-use loans require apportionment.
- Corporation Tax Relief: Limited companies can deduct interest at their corporation tax rate (currently 19-25%).
- Income Tax Relief: Sole traders/partnerships deduct at their income tax rate (20-45%).
- Annual Investment Allowance: Can claim 100% tax relief on assets purchased with loan funds (up to £1m).
- Restrictions: HMRC limits interest deductions to 30% of taxable EBITDA for loans over £2m.
Example: A £500k loan at 6% generates £30k annual interest. A limited company paying 25% corporation tax would save £7,500 in tax (£30k × 25%).
Always consult a UK tax advisor as rules differ for:
- Loans from connected parties
- Foreign currency loans
- Loans with payment-in-kind interest
