TL;DR: NHG and energy label details can affect a Dutch mortgage estimate, but they do not turn a calculator result into an approval. Use the calculator for a first number, then request a mortgage/adviser check when the home price, loan amount, energy label or planned energy-saving measures may matter.

Short answer

NHG stands for Nationale Hypotheek Garantie. It is a Dutch mortgage guarantee framework with its own cost limit, conditions and one-time fee. Rijksoverheid says the maximum NHG mortgage guarantee in 2026 is EUR 470,000. If energy-saving measures are financed inside the mortgage, the higher NHG line is EUR 498,200, and the amount above EUR 470,000 must be used for those measures: Rijksoverheid on the 2026 NHG amount.

Energy label is a separate input. It can affect borrowing room for buying a more energy-efficient home and for financing energy-saving measures. Volkshuisvesting Nederland publishes the 2026 extra borrowing amounts by label: Volkshuisvesting Nederland on maximum mortgage by energy label.

The practical point: a calculator can estimate payment and cash gap. NHG and energy label details need a check when they could change the real borrowing context.

What NHG can change in an estimate

Rijksoverheid says NHG can offer a safety net for buyers who later face personal circumstances such as relationship breakdown or disability, and that buyers with an NHG mortgage can often receive a lower mortgage interest rate: Rijksoverheid NHG news release.

Property price Check Is the property price or valuation close to the 2026 NHG limit?
Energy measures Check Are energy-saving measures part of the mortgage plan?
Loan amount Check Does the loan amount fit the relevant NHG line?
One-time fee Check Is the one-time NHG fee included in the cash plan?
Lender review Check Does the lender accept the buyer, property and documents for the intended route?

Rijksoverheid says the one-time NHG fee is 0.4% of the total mortgage amount in 2026. On a EUR 300,000 mortgage, that example fee is EUR 1,200: Rijksoverheid on the 2026 NHG amount.

What the energy label can change

The energy label can matter in two different ways. First, a better label can allow extra borrowing for the purchase compared with a home with label E, F or G. Second, some labels can allow extra borrowing for energy-saving measures.

E, F, G Purchase extra EUR 0 versus E, F or G. Energy-saving measures EUR 20,000.
C, D Purchase extra EUR 5,000 versus E, F or G. Energy-saving measures EUR 15,000.
A, B Purchase extra EUR 10,000 versus E, F or G. Energy-saving measures EUR 10,000.
A+, A++ Purchase extra EUR 20,000 versus E, F or G. Energy-saving measures EUR 10,000.
A+++ Purchase extra EUR 25,000 versus E, F or G. Energy-saving measures EUR 0.
A++++ Purchase extra EUR 30,000 versus E, F or G. Energy-saving measures EUR 0.
A++++ with guarantee Purchase extra EUR 40,000 with a ten-year energy performance guarantee. Energy-saving measures EUR 0.

Rijksoverheid also explains the simpler energy-saving route: buyers and homeowners may be able to get a higher mortgage for energy-saving measures, and the amount depends on the home energy label: Rijksoverheid on energy-saving mortgage room.

Why this calculator keeps it separate

The calculator on this site is built for a first payment estimate, not an NHG eligibility decision. It uses home price, own funds, interest rate, mortgage term and household income to give a simple gross monthly payment and cash-gap signal.

Rijksoverheid explains that the maximum amount someone can borrow depends on income and home value. It also says the mortgage can usually be up to 100% of the home value, the value is set by a taxateur, and income rules also consider interest, fixed-rate period and financial obligations: Rijksoverheid on maximum mortgage basics.

NHG and energy label details sit on top of that context. They may change the route, but they do not remove the need to check income, property value, buyer costs, lender rules and documents.

Simple decision path

Home below EUR 470,000 Why it matters NHG may be worth checking if other conditions can fit. Next step Ask whether NHG is relevant before relying on the estimate.
Close to EUR 470,000 Why it matters A small difference in value, costs or energy measures may change the route. Next step Request a check before bidding or arranging valuation.
Measures planned Why it matters The higher NHG line and extra borrowing room may depend on how measures are financed. Next step Share the planned measures and rough budget in the check.
A or better label Why it matters Purchase-related extra borrowing room may be relevant. Next step Share the definitive energy label if known.
E, F or G label Why it matters Energy-saving measure room may be more relevant than purchase-label room. Next step Ask what measure budget and lender route are realistic.
Buyer costs are tight Why it matters NHG fee, valuation, advice, notary and purchase costs can change the cash gap. Next step Read buyer costs outside a Dutch mortgage.

What to send for a useful check

Start with context rather than sensitive documents. Share:

Target home price or price range.
Whether the property has a known energy label.
Whether energy-saving measures are planned.
Rough own funds after buyer costs.
Gross annual household income range.
Buying alone or with a partner.
Existing student debt, lease obligations or other recurring debts.
Whether the question is before viewing, before bidding or after an accepted offer.

Then use the Dutch mortgage calculator for the first number and request a mortgage/adviser check when NHG or energy label details could change the decision. For broader viewing, offer and purchase-step context, use Buy a house in the Netherlands.

Next step

Use the calculator for orientation. Request a mortgage/adviser check before you rely on an NHG or energy-label assumption for a bid, valuation or buying-cost decision.

FAQ

Is NHG the same as mortgage approval? No. NHG is a guarantee framework with conditions and limits. A lender still needs to review the buyer, property, documents and mortgage application.
What is the NHG limit in 2026? Rijksoverheid says the maximum NHG mortgage guarantee in 2026 is EUR 470,000. The higher line is EUR 498,200 when energy-saving measures are financed and the amount above EUR 470,000 is used for those measures.
Does NHG cost money? Yes. Rijksoverheid says the one-time NHG fee in 2026 is 0.4% of the total mortgage amount.
Does a better energy label always mean I can buy more? No universal answer. The 2026 rules include extra borrowing amounts by label, but the final result still depends on income, property value, interest, obligations, lender policy and documents.
Can a calculator include energy label automatically? Only if it asks for the label and models the current rules. A simple calculator may leave energy label out and show a first payment estimate instead.
When should I request a check? Request a check when the property price is close to an NHG line, energy-saving measures are planned, the energy label may matter, or the calculator number may affect a viewing, bid or paid buying step.
