This page is best for a very practical construction-financing question: how much you may need to borrow, how much interest may accumulate during the build, and what the long-term monthly payment may look like once the project is finished. For many borrowers, the hard part is not one rate in isolation. It is understanding how the construction phase and the permanent-loan phase combine.
The current page separates those two phases. It estimates interest generated during construction draws and then estimates the monthly payment and total cost of the permanent loan. That makes it useful for early budgeting, down-payment comparison, and construction-timeline planning.
Project cost is the total budget for the build, while down payment is the portion you fund yourself. The page subtracts down payment from project cost to estimate the financed loan amount, so higher down payment usually reduces both construction-phase cost and long-term payment burden.
Construction period is entered in months and sets the time window over which draws can accumulate interest. Construction rate is used only for the build-stage interest estimate, not for the long-term permanent loan.
It is best for early budgeting and scenario comparison on home-building or construction financing rather than formal underwriting.
The interface includes a loan-type field, but the current calculation does not switch formulas based on it, so both paths still use the same underlying model.
No. The current total-payment figure covers construction-period interest plus long-term loan payments, not the upfront cash you provide as down payment.
No. The page uses a simplified equal-draw and evenly spaced timing model, so it is better for budgeting than for reproducing bank disbursement math.
