How to Calculate Mortgage Insurance Costs on Your Home Loan

Knowing how to calculate mortgage insurance costs helps you budget for homeownership accurately. Whether you have PMI on a conventional loan or MIP on an FHA loan, this guide breaks down the math.

Step 1: Find Your Loan-to-Value (LTV) Ratio

LTV = (Loan Amount ÷ Home Value) × 100. If your home is worth $300,000 and you borrow $255,000, your LTV is 85%.

Step 2: Determine Your PMI Rate

PMI rates range from 0.20% to 1.50% depending on your credit score and LTV. Borrowers with excellent credit and 10% down might get a 0.40% rate, while those with lower credit and 5% down might pay 1.20%.

Step 3: Calculate Annual and Monthly Premium

Annual PMI = Loan Amount × PMI Rate
Example: $255,000 × 0.80% = $2,040 per year
Monthly PMI = Annual PMI ÷ 12
Example: $2,040 ÷ 12 = $170 per month

FHA MIP Calculation Example

For a $200,000 FHA loan with 3.5% down and 30-year term:
– UFMIP: $200,000 × 1.75% = $3,500 (one-time)
– Annual MIP: $200,000 × 0.85% = $1,700 per year = $141.67/month

Conclusion

Calculating mortgage insurance before you apply gives you a realistic picture of total monthly housing costs. Always include it in your budget planning.
