Mortgage Rate Explorer

Shape a mortgage in real time.

Start with the home price, let the calculator assume a 20% down payment, then tune the cash down, term, points, and lender credits. The page estimates a current market rate and surfaces both monthly and upfront ownership costs.

Adjust the Loan

Rate Strategy Comparison

Keep the same home price, down payment, and term. Compare how buying points or taking lender credits shifts both monthly cost and long-run total paid.

Each row compares against a neutral loan with 0 points and 0 credits. Bars left of center reduce cost, bars right of center increase cost.

Mortgage Terms

The calculator surfaces the same concepts lenders use when quoting a rate.

Points

A one-time fee paid at closing to get a lower interest rate.

Credits

Money from the lender to offset closing costs in exchange for a higher interest rate.

Rate

The percentage of interest charged on the amount you borrow.

APR

The overall cost of the loan, including interest and estimated fees, shown as a single percentage.

Principal

The amount of money borrowed to buy the home before interest is added.

Rate data is pulled from public Freddie Mac mortgage series hosted by FRED when available. Estimates for points, credits, and APR are illustrative and meant for quick comparison, not a lender quote. Local cost assumptions use Cook County property tax averages, Arlington Heights home insurance averages, and a mid-range closing cost estimate.
