Construction to Permanent Loan Calculator

Introduction

A Construction-to-Permanent Loan simplifies financing by combining the building phase and conventional mortgage into one seamless process. During construction, borrowers make interest-only payments; once the home is complete, the loan converts to a traditional amortizing mortgage. This approach saves time, reduces closing costs, and locks in permanent financing terms early. Our Construction to Permanent Loan Calculator provides clear estimates for both phases, empowering homeowners and builders to plan budgets, compare lender offers, and understand cash flow requirements.

Usage Guide

1. Loan Amount ($): Enter the total construction budget plus permanent financing needs.
2. Construction Interest Rate (%): Input the variable rate during building (often index + margin).
3. Construction Period (years): Specify how long you expect construction to last (e.g., 0.5 for six months).
4. Permanent Interest Rate (%): Provide the finalized fixed rate for the mortgage phase.
5. Permanent Term (years): Enter the amortization period (commonly 15–30 years).
6. Calculate: Click “Calculate” to instantly view monthly interest-only and amortized payments.

Tip: Adjust rates by ±0.25% to simulate market fluctuations and understand payment sensitivity during both phases.

Why Construction-to-Permanent Loans Matter

Traditional two-close loans involve separate applications, two sets of closing costs, and rate uncertainty. One-close construction-to-permanent loans lock the permanent rate at the outset, eliminating refinancing risk. Borrowers benefit from streamlined paperwork, reduced fees, and predictable monthly payments after conversion.

For builders, a one-close loan ensures steady interest payments during construction and timely transition to mortgage income. Homeowners enjoy less stress and lower overall costs. According to HUD guidelines, consolidating closings helps maintain financing compliance and saves an average of 1–2% of loan amount in fees.
