If you're considering a cash-out refinance, the most important question to ask first is whether you actually need to refinance the whole mortgage — or whether a home equity loan would access the same funds at lower total cost.
Both options let you borrow against home equity. But a cash-out refinance replaces your entire mortgage at today's rates, while a home equity loan leaves your existing mortgage untouched. Depending on your current rate, one of these can be significantly more expensive than the other.
Quick Answer: Cash-out refinance or home equity loan? If your current mortgage rate is significantly lower than current market rates, a cash-out refinance is usually the worse choice — you'd be replacing a good rate on a large balance with a higher rate on a larger one. A home equity loan lets you borrow against your equity at a separate rate without touching the existing mortgage. If your current rate is already high (or close to current rates), a cash-out refinance can make more sense by consolidating into a single loan. The right answer depends heavily on what your current mortgage rate is.
How Each Option Works
Cash-out refinance You replace your existing mortgage with a new, larger loan. The difference between the new loan amount and your current balance is paid out to you in cash. The result is one mortgage payment at the new loan's rate and term.
Example: $285,000 remaining on your mortgage, home worth $425,000. Cash-out refinance for $340,000 → you receive $55,000 in cash and now have a $340,000 mortgage at whatever rate you qualify for today.
Home equity loan You keep your existing mortgage intact and take out a second loan against the equity. It's a separate fixed-rate installment loan with its own payment. You now have two monthly payments: your original mortgage and the new equity loan.
Example: Same $285,000 mortgage and $425,000 home. Home equity loan for $55,000 at a separate fixed rate → your original mortgage is untouched, and you add a second payment on the $55,000.
Both options access the same equity. The difference is what happens to the first mortgage and the rate structure of the borrowing.
The Rate Question: Why It Usually Determines the Answer
The central variable in this comparison is your current mortgage rate relative to today's rates.
If your current mortgage rate is low relative to today's rates: A cash-out refinance replaces your entire existing balance at the new (higher) rate. On a $285,000 balance, going from 3.5% to 6.5% is a large cost increase applied to a large balance. A home equity loan isolates the additional borrowing at the higher rate while leaving the existing mortgage alone.
If your current mortgage rate is already high or close to current rates: A cash-out refinance may be neutral or even beneficial — you're not giving up a good rate on the original balance. If the refinance also lowers your rate on the original balance, consolidating into one loan becomes a reasonable choice.
Illustrative comparison:
Scenario: $285,000 existing mortgage, home worth $425,000, need to borrow $55,000.
| Cash-Out Refinance | Home Equity Loan | |
|---|---|---|
| Existing mortgage rate | 3.5% | 3.5% |
| New loan amount | $340,000 | $285,000 (unchanged) |
| Rate on full amount | 6.5% (current market) | 3.5% on existing + 8.5% on $55K |
| Monthly payment (P&I) | ~$2,150 | ~$1,276 existing + ~$570 equity = ~$1,846 |
| Extra monthly cost vs. keeping current mortgage | ~+$874 on entire balance | ~+$570 on equity portion only |
In this scenario, the home equity loan preserves the 3.5% rate on the existing $285,000 and only subjects the new $55,000 to higher current rates. The cash-out refinance subjects the entire $340,000 to today's higher rate — costing significantly more per month.
Now change the assumption: your current mortgage is at 7.25% (close to or above current market):
| Cash-Out Refinance | Home Equity Loan | |
|---|---|---|
| Existing mortgage rate | 7.25% | 7.25% |
| New loan amount | $340,000 at 6.5% | $285,000 at 7.25% + $55K at 8.5% |
| Monthly payment (P&I) | ~$2,150 | ~$2,214 existing + ~$570 equity = ~$2,784 |
Here the cash-out refinance is actually cheaper per month — it lowers the rate on the existing balance and consolidates into one payment.
Beyond the Rate: Other Factors That Matter
Closing costs
A cash-out refinance replaces the entire mortgage — closing costs apply to the full new loan amount, typically 2–5%. On a $340,000 new loan, that's $6,800–$17,000 in closing costs.
A home equity loan typically has lower closing costs because it's a smaller, simpler loan — often $500–$3,000 or sometimes none, depending on the lender.
If you're only accessing $55,000, the closing cost difference between refinancing a $340,000 mortgage and taking a $55,000 equity loan is significant and favors the home equity loan in most cases.
Loan term
A cash-out refinance typically restarts the clock on the mortgage — if you refinance 15 years into a 30-year loan into a new 30-year loan, you've extended your total repayment period. This lowers the monthly payment but increases total interest paid.
A home equity loan has its own fixed term (typically 5–15 years) and doesn't affect the remaining term on the existing mortgage.
Payment structure
One payment vs. two. A cash-out refinance simplifies to a single monthly payment. Some homeowners find managing two separate payments more complex. This is a convenience factor, not a financial one — but it's real.
Prepayment flexibility
Both options typically allow prepayment without penalty, but it's worth confirming with the specific lender.
When Cash-Out Refinance Usually Makes More Sense
- Your current mortgage rate is at or above current market rates — a lower rate on the refinanced balance partially offsets the cost of the larger loan
- You want a single monthly payment and the simplicity of one loan
- You're also refinancing for rate-and-term reasons and the cash-out is an add-on to an already justified refinance
- You're accessing a large amount of equity and the per-dollar closing cost of refinancing the full loan becomes more reasonable relative to the equity accessed
When a Home Equity Loan Usually Makes More Sense
- Your current mortgage rate is meaningfully below current market rates — preserving it is valuable
- You're accessing a relatively small amount of equity where cash-out refinance closing costs would be disproportionate
- You want a fixed-rate, fixed-term second loan with predictable payments
- You don't want to restart the amortization clock on your existing mortgage
What About a HELOC?
A home equity line of credit (HELOC) is a third option worth mentioning. Unlike a home equity loan (which gives you a lump sum at a fixed rate), a HELOC is a revolving credit line with a variable rate. It's more flexible — you can draw funds as needed — but the variable rate introduces uncertainty.
For planned, defined expenses (a renovation with a known cost, debt consolidation), a home equity loan's fixed rate and fixed payment are often preferable. For ongoing or unpredictable funding needs, a HELOC's flexibility can justify the variable rate risk.
Using the Mortgage Refinance Calculator for a Cash-Out Refinance
The Mortgage Refinance Calculator is designed for rate-and-term refinance comparisons, but it can approximate a cash-out refinance scenario: enter the larger loan amount as the refinance balance, the new rate and term, and your current P&I payment. This shows you how the monthly payment and total remaining loan cost change — which is the core of the cash-out refinance comparison.
For the home equity loan side, the Mortgage Calculator can estimate the second payment on the equity amount at its rate and term.
If you want the broader refinance decision framework around break-even, loan resets, and alternative equity-access paths, the Mortgage Refinance topic page ties the main guides together.

Frequently Asked Questions
Can I do a cash-out refinance if I have an existing second mortgage or HELOC?
Generally yes, but it's more complex. The second lien must either be paid off in the refinance or subordinated (the lender agrees to remain in second position). Most lenders require existing second liens to be paid off at or before closing the cash-out refinance, which affects the total amount needed and the cost calculation.
Does a cash-out refinance affect my mortgage interest deduction?
Interest on mortgage debt used to buy, build, or substantially improve the home is generally deductible (subject to limits). Interest on cash-out proceeds used for other purposes — debt consolidation, personal expenses — may not be deductible under current rules. The tax implications depend on how the funds are used. Consult a tax advisor for your specific situation.
How much equity can I typically access?
Most lenders allow cash-out refinances up to 80% loan-to-value (LTV), meaning you can borrow up to 80% of the home's appraised value. On a $425,000 home, that's $340,000 maximum — which is exactly the loan amount in the example above ($285,000 balance + $55,000 cash-out). With less equity or a lower appraised value, the maximum cash-out amount shrinks accordingly. Some loan programs allow higher LTV, but they typically come with higher rates or PMI requirements.
Is a home equity loan a good idea for debt consolidation?
It can be — particularly if the debt carries high rates (credit cards at 20%+) and the equity loan rate is meaningfully lower. The risk is converting unsecured debt to secured debt: if you consolidate credit cards into a home equity loan and then struggle to repay, the home is now at risk in a way it wasn't before. The math can favor consolidation; the risk profile changes materially.
How does a cash-out refinance affect my break-even calculation?
A cash-out refinance typically has higher closing costs than a rate-and-term refinance (more paperwork, larger loan). The break-even concept still applies — closing costs divided by monthly savings — but the monthly payment change may be a payment increase rather than decrease if you're refinancing into a higher rate on a larger balance. In that case, break-even in the traditional sense doesn't apply: you're comparing the total cost of the cash-out refinance against the cost of a home equity loan for the same funds, not against your current mortgage.
Key Takeaways
- Your current mortgage rate is the deciding factor — a rate meaningfully below today's market strongly favors a home equity loan over cash-out refinancing
- Cash-out refinance subjects the entire balance to the new rate; on a large existing mortgage, even a modest rate increase adds substantial monthly and total cost
- Home equity loan isolates the new borrowing at current rates while leaving the original mortgage untouched — particularly valuable when the existing rate is low
- Closing costs on a cash-out refinance apply to the full new loan amount; for smaller equity needs, the cost difference compared to a home equity loan is significant
- Cash-out refinance makes sense when your current rate is at or above market, you're already refinancing for rate-and-term reasons, or simplifying to one payment has real value
