Minimum payments only: 6 yr 10 mo, interest $9,258.16, total $29,758.16 Snowball (smallest balance first): 3 yr 1 mo, interest $4,217.13, total $24,717.13 Avalanche (highest rate first): 3 yr 0 mo, interest $3,795.35, total $24,295.35 Consolidation loan: 4 yr 0 mo, $537.59/month, interest $5,604.17 incl. fees

A consolidation loan replaces several debts with one fixed payment, ideally at a lower rate. It saves money only if the rate and fees are lower and you don’t run the old cards back up. A longer term can lower the payment but raise total interest. Everything is calculated in your browser, so nothing you type is sent to our server.

How it works

Choose how many debts you have and enter each balance, rate and minimum payment, your extra monthly payment and the payoff method; optionally compare a consolidation loan.

Formula

Each month every debt gets its minimum payment; the extra payment (plus minimums freed up by debts already repaid) goes to the target debt Snowball target = smallest balance; avalanche target = highest interest rate Interest each month = balance × rate ÷ 12 Consolidation: one loan with payment = (total + fee) × i ÷ (1 − (1 + i)^−n)

Worked example

Inputs: Number of debts: 3; Debt 1 – balance: $2,500; Debt 1 – interest rate: 12 %; Debt 1 – minimum payment: $75; Debt 2 – balance: $6,000; Debt 2 – interest rate: 24 %; Debt 2 – minimum payment: $150; Debt 3 – balance: $12,000; Debt 3 – interest rate: 8 %; Debt 3 – minimum payment: $250; Extra monthly payment: $200; Payoff method: Minimum payments only; Consolidation loan rate (to compare): 11 %; Consolidation loan term: 48 months; Consolidation loan fee: $300.
Results: Total debt = $20,500; Total minimum payments = $475; Monthly payment budget = $475; Months to be debt-free = 82; Total interest = $9,258.16; Total paid = $29,758.16.
