Debt consolidation break-even calculator
Enter your numbers below. The calculator returns your real savings after origination fees, the new monthly payment, and the break-even APR (the rate the new loan must beat for the math to work in your favour). Nothing leaves your browser.

Break-even APR (new loan must beat this)
21.16%
With a 5% origination fee, any new APR above this leaves you worse off than your current debt.
The calculator assumes both paths run for 48 months at the rates shown. All inputs stay in your browser. Nothing is sent to a server.
What break-even actually means here
When you consolidate, you pay an origination fee up front (often 1% to 8% of the loan amount) and then make payments at the new APR over the loan term. Your savings come from the gap between the new APR and your current weighted-average APR. The fee eats into that saving.
The break-even APR is the threshold below which you save money and above which you lose. On a $15,000 balance with a 5% origination fee and a 48-month term replacing 24% credit card debt, the break-even is roughly 18.5%. If the lender quotes you 19% or higher, the fee plus interest costs more than your current debt would over the same period. If they quote 18% or lower, you come out ahead.
Three worked examples
Example 1: $15,000 at 24% to a 12% personal loan
A borrower carries $15,000 across three credit cards at a blended 24% APR. They qualify for a personal loan at 12% APR over 48 months with a 5% origination fee.
- Origination fee: $750 (5% of $15,000).
- New loan principal financed: $15,750.
- New monthly payment: roughly $415.
- Total interest on new loan: roughly $4,178.
- Total cost of new loan: roughly $4,928.
- Total interest on current debt over the same 48 months: roughly $8,712.
- Net saving: roughly $3,784.
- Break-even APR threshold: approximately 19.6%.
Strong consolidation case. The 12 percentage point rate drop is large enough to overcome a substantial origination fee and still produce meaningful savings.
Example 2: $40,000 at 22% to a 9% HELOC over 60 months
A homeowner carries $40,000 of credit card debt at 22% APR. They qualify for a HELOC at 9% APR with no origination fee but $400 in closing costs.
- Closing costs: $400.
- New monthly payment: roughly $830.
- Total interest on HELOC: roughly $9,815.
- Total interest on current debt over 60 months: roughly $26,360.
- Net saving: roughly $16,145.
- Break-even APR threshold: approximately 18.5%.
The math is overwhelming, but the risk profile changed completely: the debt is now secured by the borrower's house. Default leads to foreclosure rather than collection. See HELOC vs personal loan for the full risk discussion before treating this purely as a math problem.
Example 3: $8,000 at 26% to a 0% balance transfer over 18 months
A borrower carries $8,000 at 26% APR. They qualify for a 0% balance transfer card with a 3% transfer fee for a promo period of 18 months.
- Transfer fee: $240 (3% of $8,000).
- Required monthly payment to clear in promo period: roughly $445.
- Total interest paid (if cleared on time): $0.
- Total cost: $240 (just the transfer fee).
- Total interest on current debt over 18 months: roughly $1,635.
- Net saving: roughly $1,395.
Excellent option for smaller balances paid aggressively within the promo period. The critical risk: if the balance is not cleared by the end of the promo, the post-promo APR (often 20% to 30%) applies to the remaining balance, and some cards charge deferred interest dating back to day one. See balance transfer vs personal loan.
Reading the result
The calculator returns four numbers worth understanding.
- Net savings. The headline. Positive number means you save money; negative means you lose money.
- New monthly payment. What you would actually pay each month. Confirm it fits your budget. A consolidation that saves money on paper but produces an unaffordable monthly payment will fail.
- Total interest, new loan. The interest portion of the new loan over its full term.
- Break-even APR. The threshold your new APR must beat to save money. If a lender quotes you above this, the math does not work.
Sensitivity: what if the actual APR comes in higher than expected?
Many borrowers see a different APR on their final loan offer than they expected from pre-qualification. Underwriting can move the number by 2 to 4 percentage points either way. Run the calculator with a range: your hoped-for APR, plus 2 percentage points, plus 4 percentage points. If the math still works at hoped + 2, you have margin. If it only works at hoped, you do not.
Limitations the calculator does not capture
- It assumes you make on-time payments throughout. A single missed payment can wipe out a year of saving via late fees and credit score damage.
- It does not model behavioural re-accumulation on the cards being paid off.
- It does not model the value of one payment vs several (operational simplicity has real value).
- It does not model tax effects (most consolidations have none, but HELOC interest used for personal debt is not deductible per IRS Publication 936; see vs HELOC).
