Debt Consolidation Mathematical Architecture

Weighted Average APR

Weighted APR = Sum(Balance_i × APR_i) ÷ Total Balance

If the new consolidation loan APR is lower than your weighted average APR, you are engaging in profitable interest rate arbitrage that reduces interest expense.

Total Net Interest Savings

Net Interest Savings = Current Projected Interest − New Loan Total Interest

Upfront origination fees (typically 1% to 5%) are added directly into the consolidation loan principal to measure true net savings after all borrowing costs.
