Debt consolidation vs a home equity loan
By David Chen · Published October 11, 2026
Consolidating debt with a home equity loan is usually argued on the rate. That is where the argument is easiest to make and where it proves least. On the figures below an 8.00% home equity loan is genuinely cheaper than an 11.50% personal loan — for five years. Stretch the same loan to ten and it costs $3,208 more, with the rate unchanged at 8.00% throughout.
The comparison uses a $30,000 balance. Both routes are priced end to end, including the fee on one and the closing costs on the other, because the rate alone will not tell you which is cheaper.
The lower rate is not the cheaper loan
Two things move when you switch from an unsecured loan to a secured one, and only one of them is the rate. The rate falls, which helps. The fee structure changes, and the term is now yours to choose — which is a freedom that works in both directions. Set the term too long and the lower rate is applied over so many extra months that the total cost climbs well past what the higher rate would have charged.
That is the whole of the mechanism, and it is why a rate comparison is not a cost comparison. The difference between APR and interest rate is the general version of this point; here it is worked through on one specific balance.
Start with what you actually receive
The unsecured route in this example carries a 5% fee, deducted from the proceeds rather than paid separately. That single detail changes the principal, because the balance has to be grossed up before the deduction:
$30,000 ÷ (1 − 5%) = $31,578.95 borrowed, to receive $30,000
The extra $1,578.95 is real borrowing. It attracts interest, it is repaid over the 60 months, and it is the reason the unsecured column below is measured against a larger principal than the secured one. The home equity route has no equivalent gross-up — instead it carries a one-off $1,200 in closing costs, which enters the total without inflating the balance.
Four routes, priced end to end
Both products on the same $30,000, with the secured route shown at three terms. Total cost is everything paid over and above the $30,000 received — interest plus fees plus closing costs, with nothing netted off:
| Route | Rate | Term | Borrowed | Monthly | Total paid | Total cost | Of income |
|---|---|---|---|---|---|---|---|
| Unsecured personal loan | 11.50% | 60 mo | $31,578.95 | $694.50 | $41,670.20 | $11,670 | 9.26% |
| Home equity loan | 8.00% | 60 mo | $30,000.00 | $608.29 | $36,497.51 | $7,698 | 8.11% |
| Home equity loan | 8.00% | 120 mo | $30,000.00 | $363.98 | $43,677.93 | $14,878 | 4.85% |
| Home equity loan | 8.00% | 180 mo | $30,000.00 | $286.70 | $51,605.21 | $22,805 | 3.82% |
Monthly income of $7,500, which is what the final column is measured against. Total cost includes the 5% fee in the first row and the $1,200 closing cost in the other three. Aggregates are rounded to the nearest dollar; monthly payments are to the cent. Produced by our calculator and independently recomputed.
Read down the total cost column and the shape of the decision appears. The shortest secured term costs $7,698 — comfortably the cheapest of the four, and $3,972 less than the unsecured loan. The longest costs $22,805, nearly three times as much, while cutting the monthly payment to $286.70, the lowest in the table.
The term is the variable that decides it
Holding the secured rate at 8.00% and varying only the term isolates what the length of the loan is doing:
| Secured term | Monthly | Cut vs unsecured | Total cost | Change in total cost |
|---|---|---|---|---|
| 60 months | $608.29 | $86.21 | $7,698 | −$3,972 |
| 120 months | $363.98 | $330.52 | $14,878 | +$3,208 |
| 180 months | $286.70 | $407.80 | $22,805 | +$11,135 |
Monthly cut is measured against the $694.50 unsecured payment; the change in total cost is measured against the $11,670 unsecured figure. Every figure in this table also appears in the one above. Produced by our calculator and independently recomputed.
Doubling the term from 60 months to 120 cuts the payment by $244.31 and adds $7,180 to the total cost. Tripling it to 180 months cuts the payment a further $77.28 — a much smaller gain — while adding another $7,927 of cost. The first extension is a real improvement in monthly breathing room; the second is a marginal one that carries the largest price tag in the table.
The crossover sits at 120 months. Below that, the secured route is cheaper overall than the unsecured one; at 120 months and beyond, it is not. That is one specific pair of rates and one specific balance, and a different spread would move the crossover — but the fact that a crossover exists at all is the part worth keeping.
What this arithmetic leaves out, on purpose
- That the house is the collateral. This is the difference between the two products and it appears nowhere in the totals, because it is not a quantity. A secured loan converts unsecured debt into debt with a claim on your home attached. The lower rate is the compensation for that, not a gift, and the comparison above should be read knowing what has been traded away.
- Whether the rate you are quoted matches this one. 8.00% and 11.50% are illustrative figures for one borrower and one moment, and both products price on credit history, income and the lender. Your own quotes will differ, and the crossover point moves with them — which is why the useful exercise is re-running the comparison with your real numbers rather than adopting this result.
- Whether you can borrow against the house at all.A home equity loan needs sufficient equity and remaining room beneath the lender’s combined loan-to-value ceiling. That constraint is independent of everything on this page and can rule the secured column out before the arithmetic starts. How much home equity you have works through how much room a house supports.
- Where the closing cost actually lands. The $1,200 used here is a single illustrative figure for appraisal, recording and related charges, and it varies by lender and by market. It is the only entry in the secured column that is a cost rather than interest, so it is the one to verify against a real quote.
- What happens if circumstances change. A 60-month unsecured loan and a 180-month secured loan are not the same commitment in anything but balance. One is finished in five years; the other runs for fifteen with the house behind it. Neither the payment column nor the total column expresses that difference.
How to use this
- Price both routes over the same short term first. Most of the secured route’s advantage comes from the rate rather than the term, and it survives easily at 60 months. If a five-year secured loan is affordable, the decision is straightforward — the personal loan calculator prices the unsecured side of that comparison.
- Treat any term beyond about five years as a separate decision. Extending a loan to reduce the payment is a legitimate choice, but it is a choice to pay more in exchange for monthly room, and it should be made deliberately. An amortization schedule shows how little of each early payment touches the balance on a long term.
- Check the borrowing room before you shortlist the secured route. A home equity loan or line needs equity above the lender’s ceiling. HELOC versus home equity loan compares the two product shapes, and cash-out refinance versus a HELOC covers the third route to the same money.
- Establish what the payment does to your budget before choosing on total cost. The mortgage calculator prices a fixed payment over any term, which is the same arithmetic the secured column is built from.
The short version
On a $30,000 balance, an 8.00% secured loan repaid over 60 months costs $7,698 all in — $3,972 less than the 11.50% unsecured route, whose 5% fee forces it to borrow $31,578.95 to deliver $30,000. The same secured loan over 180 months cuts the payment to $286.70 but costs $22,805. The rate never changes; only the term does. The crossover is at 120 months, beyond which the cheaper rate stops producing the cheaper loan — and the house is collateral in every secured row.
Frequently asked questions
Why is the secured loan more expensive at ten years if the rate is lower?
Because the rate is applied over twice as many months. An 8.00% loan repaid over 120 months charges interest on a balance that stays outstanding far longer than an 11.50% loan repaid over 60. The lower rate reduces the cost per month of borrowing; the longer term increases the number of months you are borrowing. Past a certain point the second effect is larger, and on these figures that point sits at ten years — beyond it, the secured route costs more in total than the unsecured one.
Does the fee really mean I have to borrow more than I need?
Where a fee is deducted from the proceeds rather than paid separately, yes. To walk away with $30,000 when 5% is withheld, the loan has to be $31,578.95, because 95% of that figure is $30,000. The extra $1,578.95 is not a down payment — it is borrowing you did not want, on which you pay interest. Whether a particular loan works this way is stated in the disclosure, and some lenders charge the same cost as a separately paid fee instead, which produces a different total.
Is the 60-month secured loan the best answer then?
It is the cheapest of the four routes priced here, and that is a narrower statement than it sounds. It carries the highest secured monthly payment, $608.29, and it still uses the house as collateral. A household that cannot comfortably meet $608.29 a month has not been handed a solution by the total-cost column — it has been handed a cheaper loan with an unaffordable payment. Cheapest and most suitable are different tests, and only one of them is arithmetic.
What does a secured loan actually put at risk?
The home. An unsecured personal loan leaves a lender with no claim on the property if payments stop; a home equity loan is secured on it, which is what the lower rate is compensation for. That difference does not appear in any of the totals on this page, because it is not a number. It is the reason the lower rate exists, and it is worth pricing honestly rather than treating the saving as free money.
Should the comparison use the payment or the total?
Both, and in that order of priority. The payment decides whether the arrangement survives a bad month; the total decides whether it was a good idea. These four routes are a good illustration of why one alone is not enough: the 180-month option has the smallest payment of all, $286.70, and the largest total cost, $22,805 — more than twice what the 60-month secured loan costs. Whichever you start with, check the other before committing.
