The Formula
| Component | Formula |
|---|---|
| Monthly Payment | P × [r(1+r)^n] ÷ [(1+r)^n – 1] |
| Total Interest | (Monthly Payment × Months) – Principal |
| APR | Effective Annual Rate Including All Fees |
Step-by-Step Calculation
Here’s a UK business loan analysis with all costs.
Step 1: Calculate Monthly Payment
Determine regular payment amount:
| Loan Details | Value |
|---|---|
| Loan Amount | £50,000 |
| Interest Rate | 7.5% per annum |
| Term | 5 years (60 months) |
| Monthly Rate | 0.625% |
| Monthly Payment | £1,001 |
Calculation: Using loan formula = £1,001/month
Step 2: Calculate Total Loan Cost
Add up all costs over the loan term:
| Cost Component | Amount |
|---|---|
| Total Payments (60 × £1,001) | £60,060 |
| Less: Principal | -£50,000 |
| Arrangement Fee (2%) | £1,000 |
| Valuation Fee | £500 |
| Legal Fees | £750 |
| Total Interest & Fees | £12,310 |
Calculation: £60,060 – £50,000 + £1,000 + £500 + £750 = £12,310
Step 3: Calculate True APR
Determine effective annual percentage rate:
| Step | Calculation | Result |
|---|---|---|
| Net Loan Amount | £50,000 – £2,250 fees | £47,750 |
| Total Repayment | 60 × £1,001 | £60,060 |
| Effective APR | Including all fees | 8.9% |
Final Answer: True cost is 8.9% APR vs. stated 7.5%
What This Means
While the base rate is 7.5%, arrangement and other fees increase your effective cost to 8.9%. UK tax relief on business loan interest reduces the after-tax cost by approximately 19-25% depending on your corporation tax rate.
