What is a Construction Loan?
A construction loan is a short-term loan that finances the building of a home or major renovation. Unlike a traditional mortgage where you receive the full amount upfront, construction loans release funds in stages called "draws" as construction milestones are completed.
Most construction loans convert to a permanent mortgage once the build is complete — this is called a construction-to-permanent (C2P) loan, and it's the most common structure for owner-occupied new construction.
How Construction Loan Interest Works
During construction, you only pay interest on the amount drawn — not the full loan amount. This is called an interest-only period.
**Example:** - Loan amount: \$400,000 - Month 1 draw: \$50,000 → interest payment on \$50,000 - Month 6 draw: additional \$100,000 → interest payment on \$150,000 - Month 12: fully drawn → interest payment on \$400,000
Monthly payments increase as more funds are drawn. This calculator shows you exactly what to expect each month.
Draw Schedules Explained
**Even (Straight-Line):** Funds are released in equal amounts each month. Predictable and simple. Common for straightforward residential construction.
**Front-Loaded:** More funds released early (foundation, framing, mechanical rough-ins tend to be expensive). You pay more interest earlier but finish with lower balances.
**Back-Loaded:** Larger draws toward the end (finishing work, fixtures, landscaping). Lower early interest payments but higher balances later.
Your lender may have their own draw schedule tied to construction inspections. Use this calculator to model different scenarios.
Construction-to-Permanent (C2P) Loans
C2P loans combine the construction loan and permanent mortgage into a single closing. Benefits:
- **One closing**: Pay closing costs only once instead of twice - **Rate lock options**: Some lenders let you lock your permanent rate at closing - **Smoother transition**: Automatic conversion — no second application needed
Alternative: A standalone construction loan requires a separate mortgage application and closing when construction ends. More flexible but two sets of closing costs.

FAQs
Q: What down payment do I need for a construction loan? A: Most lenders require 20-25% down for construction loans. Some programs (like FHA or VA construction loans) allow less, but they have additional requirements.
Q: Can I use land I already own as equity? A: Yes. If you own land free and clear, its value typically counts as part of your down payment. Enter the land value in the calculator and it will be factored into your loan-to-value ratio.
Q: What happens if construction goes over budget? A: Construction loans have a fixed maximum draw amount. Cost overruns must be paid from your own funds. Build a 10-15% contingency buffer into your budget.
Q: Are construction loan rates higher than mortgage rates? A: Yes, typically 0.5-2% higher than permanent mortgage rates. Lenders take on more risk during construction since the collateral isn't yet complete.
Q: Do I have to make payments during construction? A: Yes — interest-only payments are due monthly on the drawn balance. Some lenders allow interest reserves (rolling interest into the loan balance), but this increases your total loan amount.
Q: What is an inspector draw? A: Many lenders require a third-party inspection before releasing each draw. The inspector confirms the work is complete before funds are disbursed.
