Pool Financing in Illinois
What it actually costs to borrow for a pool, and which route is cheapest for your situation.
Most Illinois homeowners pay for a pool one of four ways: a home equity loan (averaging about 7.4% in August 2026), a HELOC (about 7.2%, usually variable), an unsecured pool loan (roughly 8% to 20%), or cash. Equity money is the cheapest because your house secures it. On a $100,000 pool with 20% down, the difference between a 7.4% and a 9.99% rate is about $120 a month.
What a Pool Costs Per Month
Assuming 20% down and a 15 year term, which is the common shape for a pool loan. The two rate columns are the practical spread between borrowing against your house and borrowing without collateral.
| Pool price | Financed | At 7.4% | At 9.99% |
|---|---|---|---|
| $50,000 | $40,000 | $370/mo | $430/mo |
| $75,000 | $60,000 | $550/mo | $640/mo |
| $100,000 | $80,000 | $740/mo | $860/mo |
| $150,000 | $120,000 | $1,110/mo | $1,290/mo |

Four Ways People Pay for a Pool
Home equity loan
about 7.4% on average, roughly 6% to 18% depending on lender and credit
A fixed lump sum against the equity in your house, repaid on a set schedule.
The lowest rates of the four, because your house is the collateral. That is also the risk: miss enough payments and the house is what is on the line.
HELOC
about 7.2% on average, and usually variable
A revolving credit line against your equity that you draw from as the build bills come in.
Draw only what the project actually uses, which suits a build that comes in stages. The rate can move against you, so a long payoff is a bet on rates.
Pool or home improvement loan
about 8% to 20%, from roughly 7.8% for strong credit
An unsecured fixed-rate installment loan, often through a lender that specializes in pools. Terms run 10 to 30 years.
No equity required and no lien on the house, and funding is fast. You pay for that with a higher rate than either secured option.
Cash, or building in stages
no interest
Pay outright, or build the pool now and add the patio, heater, or automation in later seasons.
Costs the least over time. Phasing does mean paying mobilization twice on some trades, so it is cheaper than borrowing but not free.
What Moves Your Rate
Credit score does most of the work. Most pool lenders start around 650, and the headline rates near 7.8% generally want scores in the 700s. Equity matters for the secured routes: lenders quote their best pricing under about 70% combined loan-to-value. Term length changes the shape of the deal rather than the rate, and a longer term buys a smaller payment at the cost of far more interest overall.
Rates also vary more between lenders than most people expect, from roughly 6% to 18% for the same borrower profile. Getting two or three quotes is worth more than optimizing anything else on this page.

Pool Financing Questions
For most homeowners with equity, a home equity loan or HELOC is the cheapest money available, averaging around 7.2% to 7.4% in August 2026 versus 8% to 20% for an unsecured pool loan. The trade is that your house is the collateral. If you do not have equity or do not want a lien on the house, an unsecured pool loan costs more but funds quickly.
Most pool lenders look for 650 and up, and the advertised rates near 7.8% generally require scores in the 700s or higher. Below about 650 you will still find offers, but at rates high enough that the interest can rival the cost of the pool over a long term. Check the total repaid, not the monthly payment.
With 20% down, $80,000 financed over 15 years runs roughly $740 per month at 7.4% and about $860 per month at 9.99%. Shortening the term to 10 years raises the payment to roughly $950 and cuts total interest substantially. These are example figures, not offers.
Often yes, if you can wait. Building the pool now and adding the patio, heater, or automation in a later season spreads the cost without interest. The catch is that some trades charge to mobilize twice, so phasing saves less than the sticker difference suggests. It still usually beats borrowing at 10%.
