How the builders loan calculator works
Interest during construction = loan × average drawn % × rate ÷ 12 × months. After the build, the permanent payment uses the standard loan formula.
Frequently asked questions
Why average drawn %?
Money is drawn in stages, so you pay interest only on the amount used so far.
