About Blended Interest Rates

A blended interest rate is the weighted average interest rate of multiple loans or credit lines. When considering debt consolidation or refinancing, understanding your blended rate helps determine if a new loan offer is truly beneficial.

When to Use a Blended Rate
  • Debt Consolidation: When combining multiple loans into a single new loan
  • Mortgage Refinancing: When combining a primary mortgage with a home equity loan
  • Student Loan Consolidation: When merging multiple student loans with different rates
  • Business Loan Analysis: When analysing the effective cost of multiple business financing sources
Benefits of Knowing Your Blended Rate
  • Accurately compare consolidation offers against your current situation
  • Understand the true cost of your existing debt
  • Make informed decisions about which debts to pay off first
  • Evaluate if a debt consolidation loan actually saves you money
Example

If you have a mortgage with a £200,000 balance at 4% interest and a car loan with a £20,000 balance at 6% interest, your blended rate would be:

Blended Rate = (£200,000 × 4% + £20,000 × 6%) ÷ £220,000 = 4.18%

This means that if you're offered a consolidation loan at 4.1%, it would be beneficial, but if offered at 4.3%, you would actually pay more interest overall.
