Does Refinancing Pay Off in Illinois Right Now?

Typical Illinois refinance: $211,000, 27 years left at 7.891%, new 30 year loan at the MonitorBankRates Illinois average of 7.141%Amount
Current monthly principal and interest$1,576
New monthly principal and interest$1,424
Monthly savings$152
Break even on $5,300 closing costs35 months
Interest left on the current loan$299,621
Interest on the new 30 year loan$301,577
New payment on a 15 year loan at 6.639%$1,854

Refinancing into a fresh 30 year term lowers the payment by $152 a month but adds three years of payments, so the interest comparison is $299,621 left on the current loan against $301,577 on the new one, which means the new loan costs more over its life despite the lower payment. Refinancing the same balance into a 15 year loan at the Illinois average of 6.639% raises the payment to $1,854 but cuts lifetime interest to about $122,756. The usual rule of thumb is that a refinance is worth pricing when today's rate is at least half a point to three quarters of a point below your current rate and you plan to stay past the break even point.

The Illinois Refinance Market

Refinance pricing versus purchase pricing. Across 11 lenders that publish separate purchase and refinance rates nationally, the refinance rate runs about 0.057 points above the same lender's purchase rate. The rates in the tables above are as published; this premium is context, not an adjustment.

Closing costs in Illinois. Refinance closing costs typically run 2% to 5% of the loan, which on the typical Illinois refinance of $211,000 is $4,200 to $10,600. The largest items are the lender's origination fee, the appraisal, title insurance and recording charges, plus prepaid interest and escrow deposits. A no closing cost refinance shifts those charges into a higher rate, so run both versions through the calculator before choosing.

Home values and equity. The median Illinois home is worth about $263,300, and the state scores 102.8 on the MBR Housing Affordability Index (rank 26 of 51, 100 is the national average). Most conventional refinances need at least 20% equity to avoid private mortgage insurance; if your balance is under 80% of your home's current value, a rate and term refinance at today's Illinois average usually qualifies without PMI. See the Illinois housing affordability page for the full picture.

How to Use the Illinois Refinance Calculator

  • Enter your current loan

    Type in your balance, your rate and the years you have left, from your most recent statement. If the statement shows the principal and interest payment, enter it and the calculator uses it instead of recomputing.

  • Pick the new Illinois rate

    The new rate starts at today's MonitorBankRates Illinois average. Click a verified lender offer in the rate panel to test that rate and term, or type the rate you were quoted. Choose 15, 20 or 30 years.

  • Set the closing costs

    The default is 2.5% of your balance. Replace it with the figure on your Loan Estimate. Check the box to roll the costs into the loan if you would rather not pay them at closing; the calculator then charges interest on them like the rest of the balance.

  • Read the verdict

    The calculator shows monthly savings, the break even point, lifetime interest saved and what happens if you keep paying your current amount on the new loan, which is how most people capture a lower rate without restarting the clock.

Frequently Asked Questions About Refinancing in Illinois

What is the average refinance rate in Illinois today?

The MonitorBankRates Illinois average for a 30 year fixed mortgage is 7.141% as of September 24, 2026, and the 15 year average is 6.639%. Most lenders price refinances from the same rate sheet as purchase loans, though among lenders that publish separate refinance pricing nationally the refinance rate averages 0.057 points higher. Individual lenders currently advertise 30 year rates from 5.49% to 6.75%, so compare offers on the Illinois refinance rates page.

How much can I save by refinancing in Illinois?

On the typical Illinois refinance of $211,000 with 27 years left at 7.891%, a new 30 year loan at today's MonitorBankRates Illinois average of 7.141% cuts the payment from about $1,576 to $1,424, a saving of $152 a month. With $5,300 in closing costs the break even point is about 35 months. Savings scale with the balance and the size of the rate drop; the tables above show both.

How much does it cost to refinance a mortgage in Illinois?

Refinance closing costs typically run 2% to 5% of the loan amount. On the typical Illinois refinance of $211,000 that is roughly $4,200 to $10,600, covering the origination fee, appraisal, title insurance, recording charges and prepaid escrow items. Lenders that advertise no closing cost refinances recover those costs through a higher rate.

When does refinancing make sense in Illinois?

Refinancing usually makes sense when today's rate is at least 0.5 to 0.75 points below your current rate, you plan to stay in the home past the break even point, and you are not stretching a nearly paid off loan back to 30 years. At today's MonitorBankRates Illinois average of 7.141%, that means current rates of about 7.641% and above are worth pricing. Switching from an adjustable rate to a fixed rate, or dropping PMI after building 20% equity, can justify a refinance even with a smaller rate drop.

What is a break even point and how do I read it?

The break even point is the number of months you must keep the new loan before your monthly savings cover the closing costs. If closing costs are $5,300 and you save $152 a month, the break even is 35 months. After that point every additional month is savings; sell or refinance again before it and the refinance cost you money.

Should I refinance to a 15 year or a 30 year loan?

A 15 year loan carries a lower rate (6.639% in Illinois today versus 7.141% for 30 years) and far less lifetime interest, but the payment is much higher: about $1,854 versus $1,424 on the typical Illinois refinance. Choose the 15 year if that payment fits comfortably. Otherwise take the 30 year and keep paying your current amount; the calculator shows how many years that shaves off.

How much equity do I need to refinance in Illinois?

Most conventional lenders want at least 20% equity to refinance without private mortgage insurance, meaning a balance under 80% of the home's appraised value. With the median Illinois home worth about $263,300, that is a balance under roughly $210,640 on a median priced home. You can often refinance with less equity, but PMI is added to the payment. FHA streamline and VA IRRRL programs have more lenient requirements for qualifying borrowers.

Does refinancing reset my loan?

Yes. A refinance pays off the old loan and starts a new amortization schedule. Refinancing 27 remaining years into a new 30 year loan adds three years of payments, which is why the calculator compares lifetime interest, not just the monthly payment, and shows the keep your current payment scenario that avoids extending the payoff date.
