NHG Calculator: What the Dutch Mortgage Guarantee Costs

NHG is cheaper to work out than most people expect: you pay a one-off premium of 0.4%of your mortgage amount, and that premium is tax-deductible. Below you’ll find the cost limit and a few worked examples, so you can see in one glance what NHG means for you.

What is NHG?

NHG stands for Nationale Hypotheek Garantie— the Dutch national mortgage guarantee. It’s a safety net. If you’re forced to sell your home at a loss because of job loss, disability, divorce or the death of a partner, and a residual debt is left over, the guarantee fund can write that debt off. On top of that, NHG almost always earns you a lower mortgage interest rate, because the lender takes on less risk. That discount varies by lender but is typically around 0.3% to 0.6%.

What does NHG cost? The calculation

The maths is simple. The NHG premium is 0.4% of your mortgage amount (0.004), you pay it once when you take out the mortgage, and you can deduct the full amount on your tax return. So:

NHG premium = 0.4% × mortgage amount

Mortgage amountNHG premium (0.4%)
€250,000€1,000
€350,000€1,400
€450,000€1,800

Because the premium is tax-deductible, your net cost is lower still. And once you factor in the interest discount, buyers often recover the one-off premium within two to three years.

The cost limit: up to €470,000

You can only get NHG if the purchase price (and your total mortgage) stays below the cost limit. For 2026 that limit is €470,000. If the property costs more, NHG is off the table — even by a single euro. A higher limit applies if you borrow extra for energy-saving improvements; the exact figures are in our knowledge-base article on NHG.

Pros and cons

  • Lower interest rate. Almost every lender discounts a mortgage with NHG.
  • Residual-debt protection. In a forced sale, your remaining debt can be written off.
  • Deductible premium. The one-off 0.4% is tax-deductible.
  • Downside: the upfront premium. You pay the 0.4% at the start, and above the cost limit NHG isn’t available.
