Stuck on LTV maths for your CeMAP exam? You’re not alone. Understanding how to calculate Loan to Value (LTV) ratios is a fundamental skill for aspiring mortgage advisers. This guide breaks down the LTV calculation process into manageable steps, providing clear explanations and worked examples to build your confidence. By mastering this concept, you’ll be better prepared for your CeMAP exams and your future career in mortgage advice.
📉 What Is Loan to Value (LTV)?
Understanding LTV
- Definition: LTV is the ratio of the loan amount to the property’s value, expressed as a percentage.
- Importance: Lenders use LTV to assess risk; a higher LTV indicates higher risk.
- Impact: LTV affects mortgage rates, approval chances, and insurance requirements.
Real-World Example
- If you’re buying a home valued at £200,000 with a £150,000 mortgage, your LTV is 75%.

📝 Step-by-Step LTV Formula
The LTV Calculation Formula
LTV (%) = (Loan Amount ÷ Property Value) × 100
✔️ Worked Example
- Property Value: £250,000
- Loan Amount: £187,500
- Calculation: (£187,500 ÷ £250,000) × 100 = 75% LTV
⚠️ Common Pitfalls
- Using the purchase price instead of the appraised value.
- Forgetting to convert the ratio into a percentage.

🧠 Why LTV Matters in Mortgage Advising
Risk Assessment
- Higher LTVs may lead to higher interest rates and stricter lending criteria.
Client Guidance
- Advising clients on how their deposit size affects their LTV and mortgage options.
Regulatory Compliance
- Understanding LTV thresholds is crucial for compliance with lending regulations.
