What debt consolidation really costs
Consolidating has two prices — and one of them is hidden.
- A consolidation loan costs you its rate plus an origination fee taken off the top.
- A balance-transfer card costs a transfer fee now, and a high rate later if you don't clear it in time.
- It only pays off if the new rate and fees beat what you pay today.
- The catch: a "0%" card hides the transfer fee today and the standard rate later.
The three numbers that decide it
The consolidation loan: two numbers
A consolidation loan pays off your cards and leaves you one fixed payment. Two numbers set its cost. The first is the APR (APR, the yearly cost of borrowing as a percent). The second is the origination fee.
That fee is taken from the loan amount, so you receive less than you borrow. Borrow $10,000 at a 5% origination fee and about $500 comes off the top — you get $9,500 in hand but repay the full $10,000 plus interest. Count the fee as part of the price, not a footnote.
The balance-transfer card: watch the second number
A balance-transfer card moves your card debt onto a new card at 0% for a set number of months. Two numbers matter here too. The first is the transfer fee, usually 3–5% of what you move.
The second number is the one people miss: the rate after the promo ends. If you don't clear the balance inside the promo window, whatever is left jumps to the card's standard rate — often 20% to 25%+. The 0% is a deadline, not a discount. Miss it and the leftover balance costs more than the card you left.
Does it actually save you money?
Run the two options against what you pay now. Say you owe $10,000 across cards at a blended 24% rate.
The loan beats the cards even after its fee. The card beats the loan — but only if you clear the balance before month 15. Leave $4,000 on it past the deadline and it starts charging 25%, and the math flips.
The advertised 0% is the headline. It hides two costs: the transfer fee you pay today, and the standard rate you pay later on anything left over.
Plan to the deadline, not the offer. Divide the balance by the promo months — that's the payment you have to make every month to clear it in time. If you can't hit it, price the card at its standard rate before you sign.
The rule
Consolidation only pays off when two things are both true: the new rate plus its fees beat what you pay now, and you finish before any promo rate expires. If either fails, you're moving debt, not shrinking it.
