FHA Loan Calculator

There is a cliff in the FHA rules at exactly ten percent down, and it is worth more than almost any other decision in the transaction. Mortgage insurance on an FHA loan runs for the life of the loan where the loan-to-value is above ninety percent, and stops after eleven years where it is ninety or ...

$6,755 upfront, financed into the loan, plus 0.55% a year running for the entire 30 years, because the loan-to-value of 96.5% is above ninety percent.

$26,000 more deposit would save $24,138 of insurance. Ten percent down puts the loan-to-value at exactly ninety, which is the line where the premium stops after eleven years instead of running the full term. It is a step, not a slope — a deposit of 9.9% is on the wrong side of it, and the difference between the two is a few hundred dollars of cash and roughly nineteen years of premiums.

You borrow more than the house costs. The upfront premium of $6,755 is added to the loan rather than paid at closing, so a $400,000 purchase with $14,000 down produces a $392,755 mortgage — 98.2% of the price. That financed premium then accrues interest for the whole term, which is a cost the headline rate does not show.

A note on how this is calculated. The annual premium is charged on the average balance for each year and recalculated annually, so it falls as the loan amortises. Many calculators apply the rate to the original loan for the whole term, which overstates a thirty-year premium substantially. The figures here use the declining basis, which is why they may look lower than elsewhere. This is still an estimate rather than a quote.

That vertical drop is the whole decision. Everywhere else on the curve, more deposit reduces the insurance gently, because the premium is a percentage of a smaller loan. At exactly ten percent the duration rule flips and the cost falls off a cliff. It is the only place in this category where a few hundred dollars of deposit is worth tens of thousands.

HOW TO USE

  1. 1

    Enter the price and the deposit you have in mind. If it lands anywhere between five and ten percent, move it to exactly ten and watch the total insurance figure — that step is the most valuable thing on the page.

  2. 2

    Set your credit score honestly. Below 580 the minimum deposit is ten percent rather than 3.5%, which rules out the low-deposit route but does put you on the better side of the duration rule.

  3. 3

    Note that the total borrowed is more than the price less your deposit. The upfront premium is added to the loan, and it accrues interest like everything else.

  4. 4

    Open the conventional comparison if your deposit is under twenty percent. FHA insurance is usually dearer over time but the interest rate is often lower, so the two partly offset.
