About this calculator

When debt is spread across several loans, the headline rate on any one of them is misleading. This calculator weights every balance by size to produce your true blended rate — the number that tells you whether consolidating or refinancing actually helps.

What it shows you

  • Your weighted blended rate across all debts
  • Each loan's contribution to the blended rate
  • A before-and-after view when consolidating
  • Whether a new single loan beats the current mix
  • Total interest under blended vs. consolidated scenarios

Why it matters

Consolidation pitches live or die on the blended rate. Showing the honest, weighted number — not just the lowest rate in the pile — is what separates a trusted advisor from a salesperson.
