Understanding Debt Consolidation
How Debt Consolidation Works
- Process:Take out a new loan to pay off existing debts, then make one monthly payment to the new lender
- Goal:Lower interest rate, reduced monthly payment, or both
- Types:Personal loans, balance transfer credit cards, home equity loans, or debt consolidation loans
When Consolidation Makes Sense
- Good Candidates:Multiple high-interest debts (APR above 15%), good credit score (700+), stable income
- Calculate Savings:Compare total interest paid on existing debts vs. consolidation loan over the same timeframe
- Factor in Fees:Origination fees (1-5%) and balance transfer fees (3-5%) must be less than interest savings
Credit Score Impact
- Short-term:5-10 point dip from credit inquiry and new account
- Long-term:30-60 point improvement from lower utilization and positive payment history
- Strategy:Keep old accounts open with zero balance to maintain available credit and maximize score gains
How the Math Works
Weighted Average APR
where Bi is the balance of debt i and ri is its APR. If the consolidation loan rate is below this weighted average, consolidation reduces your interest cost.
- Bi (Balance):Outstanding balance on each individual debt
- ri (Rate):Annual percentage rate on each debt, as a decimal
- n (Count):Total number of debts being consolidated
Consolidation Loan Payment
where P is the total consolidated principal (sum of all balances plus any origination fee financed), rc is the monthly consolidation rate (annual rate ÷ 12), and n is the number of monthly payments.
- P (Principal):Sum of all existing balances, plus origination or balance transfer fees if financed into the loan
- rc (Monthly Rate):Consolidation loan APR ÷ 12
- n (Term):Loan term in months (e.g., 60 months for a 5-year loan)
Net Savings Calculation
The calculator compares total cost under each scenario:
Worked example: You have a $6,000 credit card at 22% APR ($150 min) and a $4,000 card at 19% APR ($100 min). Total balance: $10,000. Weighted APR: (6000 × 0.22 + 4000 × 0.19) / 10000 = 20.8%. A 5-year consolidation loan at 10% APR with 3% origination fee ($300) gives a monthly payment of $212.47. Total interest on the consolidation loan is $2,748 + $300 fee = $3,048. Paying existing debts at minimums-only costs roughly $5,400 in interest. Net savings ≈ $2,352.
- Break-Even Point:Consolidation fees must be recouped through interest savings; if the fee exceeds savings, consolidation loses money
- Term Extension Risk:A longer consolidation term lowers monthly payments but may increase total interest even at a lower rate
2026 Interest Rate Considerations
Fixed vs Variable Rates
- Protection:Fixed-rate consolidation locks in your rate regardless of Fed policy changes
- Timing:Consolidate before rates potentially rise further to maximize savings
- Comparison:Compare fixed consolidation rates to your current variable rates, not just today's rates
