Estimate your
construction loan payments.
See interest-only payments stage by stage as your construction loan balance grows with each draw, plus total interest paid before it converts to a permanent mortgage.
Assumes draws land evenly across the build (2.0 months per stage) and interest-only payments on the outstanding balance at each stage.

Payments by draw stage.
Simplified estimate only, not a loan quote. Assumes interest-only payments and evenly spaced draws - actual draw schedules, timing, and rates are set by your lender and vary by project. Interest before the loan converts to a permanent mortgage. Default rate reflects the 2026 weighted-average construction loan rate (~8.4%, roughly SOFR plus a 2.5-4% lender spread); market rates for one-time-close construction loans currently run about 6.5-9.25%.
Most construction loans are interest-only during the build and are paid out in draws as work is completed. Your payment grows at each draw stage because you only pay interest on the portion of the loan that has actually been disbursed, not the full amount up front.
Most construction loans convert to a permanent mortgage once the home is complete, often called a construction-to-permanent loan. At that point payments typically shift from interest-only to standard principal-and-interest.
It varies by lender and project size, but five to six draw stages tied to major milestones (foundation, framing, mechanicals, drywall, finishes, completion) is common for a custom home build.
