The 30-second answer
At today's typical home equity loan rate of 8% APR, a $150,000 home equity loan costs $1,254.66 per month on a 20-year term. Shorter terms mean higher monthly payments but far less interest paid overall: $1,819.91/mo at 10 years, $1,433.48/mo at 15 years, $1,100.65/mo at 30 years. Unlike a HELOC, this rate is fixed for the life of the loan - your payment never changes.
How a home equity loan differs from a HELOC
A home equity loan (sometimes called a "second mortgage") gives you all $150,000 in a single lump sum at closing. You then pay it back on a fixed schedule at a fixed rate, exactly like a first mortgage. No draw period. No variable rate. No payment shock at year 11.
A HELOC, by contrast, is a revolving credit line where the payment starts as interest-only and later switches to full amortization. HELOCs are typically variable rate. Home equity loans are typically fixed rate.
Which is right for you depends on how you plan to use the money. If you need the full $150,000 upfront (buying an investment property, paying off a specific debt, completing a defined renovation), the fixed home equity loan is usually the safer choice. If you want to draw over time (staged renovation, emergency reserve), a HELOC gives you more flexibility.
$150,000 home equity loan monthly payment at common rates and terms
| APR | 10-Year | 15-Year | 20-Year | 30-Year |
|---|---|---|---|---|
| 6.0% | $1,665.31 | $1,265.79 | $1,074.65 | $899.33 |
| 7.0% | $1,741.63 | $1,348.24 | $1,162.95 | $997.95 |
| 8.0% (typical 2026) | $1,819.91 | $1,433.48 | $1,254.66 | $1,100.65 |
| 9.0% | $1,900.14 | $1,521.40 | $1,349.59 | $1,206.93 |
| 10.0% | $1,982.26 | $1,611.91 | $1,447.53 | $1,316.36 |
| 11.0% | $2,066.25 | $1,704.90 | $1,548.28 | $1,428.49 |
Formula: PMT = P × [r(1+r)n] / [(1+r)n - 1], where P is the loan amount ($150,000), r is monthly rate (APR / 12), and n is total months. This is the same amortization math used on a first mortgage.
The trade-off: monthly payment vs. total interest
Longer terms lower your monthly payment - but you pay more interest over the life of the loan. Here is what $150,000 at 8% APR actually costs at each term:
| Term | Monthly Payment | Total Paid | Total Interest |
|---|---|---|---|
| 10 years | $1,819.91 | $218,390 | $68,390 |
| 15 years | $1,433.48 | $258,026 | $108,026 |
| 20 years | $1,254.66 | $301,118 | $151,118 |
| 30 years | $1,100.65 | $396,233 | $246,233 |
Notice the pattern: doubling the term from 15 to 30 years drops the monthly payment substantially, but the total interest paid balloons because you owe interest for twice as long. The 10- or 15-year term is the mathematically cheapest path if you can afford the payment.
Five things that change your actual $150,000 home equity loan payment
1. Your credit score. Home equity loan rates scale with FICO. A borrower at 780+ typically qualifies 1-1.5 points below a 660 borrower. On $150,000 over 20 years, that spread is significant.
2. Your combined loan-to-value (CLTV). Lenders look at your first mortgage balance plus the new home equity loan divided by your appraised value. Most cap CLTV at 80-85%. Lower CLTV means lower rate.
3. The term you choose. Shorter term = lower rate (usually), lower total interest, higher monthly payment. Longer term = higher rate, more total interest, lower monthly payment.
4. The lender. Home equity loan pricing varies significantly. Get at least three quotes. On a $150,000 loan, a 0.5% rate difference is real money over 20 years.
5. Points and closing costs. Some lenders offer a lower rate in exchange for paying discount points at closing. Do the math: divide the closing cost by the monthly payment savings to see how many months it takes to recoup.

Frequently asked questions
What is the monthly payment on a $150,000 home equity loan?
A $150,000 home equity loan at 8% APR costs $1,254.66/month on a 20-year term. On a 15-year term, the same loan runs $1,433.48/month. On a 10-year term, it is $1,819.91/month. Home equity loans are fixed rate, so the payment does not change over the life of the loan.
How is the home equity loan payment calculated?
Home equity loans amortize over a fixed term using the standard installment formula: PMT = P x [r(1+r)^n] / [(1+r)^n - 1], where P is the principal, r is the monthly interest rate (APR / 12), and n is the number of payments. For a $150,000 loan at 8% over 20 years: PMT = $1,254.66/month.
Does a $150,000 home equity loan payment change over time?
No. Home equity loans use a fixed interest rate and a fixed monthly payment for the entire term. Once you close, your payment on the $150,000 loan is locked in. This is the primary difference from a HELOC, whose payment moves with prime rate.
What is the monthly payment on a $150,000 home equity loan at 10% APR?
At 10% APR, a $150,000 home equity loan runs $1,447.53/month on a 20-year term, $1,611.91/month on 15 years, and $1,982.26/month on 10 years.
Home equity loan or HELOC for $150,000?
A home equity loan gives you a fixed rate and predictable payment. A HELOC gives you flexibility (draw only what you need, when you need it) but the rate is variable. For a $150,000 amount, pick the loan if you need all the money now and want payment certainty; pick the HELOC if you want to draw over time.
