Borrower insurance comparison 2026: a key factor in buy or rent decisions

Borrower insurance comparison 2026: why it matters for buy or rent decisions

In 2026, borrower insurance has become a major cost item in any mortgage. With loan rates around 3.6% and insurance rates typically between 0.25% and 0.45%, insurance can account for 20–35% of the total financing cost. When you try to decide whether to buy or rent, ignoring the insurance rate completely distorts the result.

In the buy-or-rent.net simulator, the key parameter for this topic is taux_assurance (insurance rate). A change of just 0.10 percentage point on this rate can represent several thousand euros over 20–25 years.

1. What does borrower insurance cover in 2026?

Borrower insurance usually includes:

• Death: remaining capital is repaid to the bank.
• Total and irreversible loss of autonomy.
• Disability / incapacity to work: partial or full coverage of monthly payments.
• Sometimes unemployment cover (optional and often expensive).

For buyers, insurance is almost always required. For tenants who keep renting, this cost simply does not exist: they only pay home insurance, which is much cheaper. That’s one of the biggest structural differences in any serious buy or rent calculation.

2. How the insurance rate (taux_assurance) is calculated

The simulator uses a taux_assurance expressed as a yearly percentage of the loan amount. Typical ranges in 2026:

• Delegated insurance: 0.20%–0.30% for young, healthy borrowers.
• Bank group policy: often 0.30%–0.45%, sometimes more depending on age and risk profile.

A common simplified formula for comparison is:

Yearly insurance cost ≈ Loan amount × taux_assurance

Over the full term, this gives:

Total insurance cost ≈ Loan amount × taux_assurance × term (years)

This is accurate enough for an insurance comparison and to see the impact in a buy or rent simulator.

3. Numerical example: €300,000 over 25 years in 2026

Assumptions:

• Property price: €300,000.
• Loan: €300,000 over 25 years.
• Nominal interest rate: 3.6%.
• Two taux_assurance scenarios: 0.25% vs 0.40%.

3.1. Insurance cost at 0.25%

• Yearly cost ≈ 300,000 × 0.25% = €750.
• Over 25 years ≈ 750 × 25 = €18,750.
• Monthly insurance ≈ 750 / 12 ≈ €62.50.

3.2. Insurance cost at 0.40%

• Yearly cost ≈ 300,000 × 0.40% = €1,200.
• Over 25 years ≈ 1,200 × 25 = €30,000.
• Monthly insurance ≈ 1,200 / 12 = €100.

3.3. Gap between the two offers

• Monthly difference ≈ 100 − 62.50 = €37.50/month.
• Total difference ≈ 30,000 − 18,750 = €11,250.

Just by choosing a better insurance contract, a thorough insurance comparison can save over €11,000. In a buy or rent framework, those €37.50/month could, if you keep renting, be invested in financial assets (ETFs, savings accounts, bonds) at a positive investment rate.

4. Impact of taux_assurance on total monthly payment and cash flow

Let’s keep the same example to illustrate the buy or rent trade-off.

4.1. Monthly mortgage payment excluding insurance

For €300,000 over 25 years at 3.6%:

• Monthly payment (principal + interest, no insurance) ≈ €1,521.

4.2. With insurance at 0.25%

• Total monthly ≈ 1,521 + 62.50 = €1,583.50.

4.3. With insurance at 0.40%

• Total monthly ≈ 1,521 + 100 = €1,621.

The €37.50/month difference looks small, but over 25 years it compounds with other costs: notary fees, agency fees, property tax and renovation costs. In the simulator, those €37.50/month can also be compared to a slightly lower rent, with an investment rate applied to the money you save by not buying.

5. Insurance comparison 2026: bank group vs delegated insurance

5.1. Bank group insurance

• Rates often between 0.30% and 0.45%.
• Less tailored: many borrowers get the same rate.
• Very convenient to set up, rarely the cheapest option.

5.2. Delegated insurance

• Rates can go down to 0.20%–0.30% for solid profiles.
• More personalised: age, health, job, smoker/non-smoker.
• Typical savings of €5,000–€15,000 over the life of the loan.

For a realistic buy or rent calculation, it’s useful to test at least two taux_assurance scenarios in the simulator:

• Scenario A: taux_assurance = 0.40% (bank group policy).
• Scenario B: taux_assurance = 0.25% (delegated insurance).

You will see how the total cost of the “buy” option moves closer to, or further from, the “rent + invest” option.

6. Insurance and other key parameters in a buy or rent model

The taux_assurance does not work in isolation. In a full buy or rent comparison, it interacts with:

• Loan rate (around 3.6%): the higher the loan rate, the higher the relative share of insurance in the total cost.
• Annual inflation: erodes the real value of future payments, including insurance premiums.
• Annual rent increase (linked to rental indexes): if rents rise quickly, buying becomes relatively more attractive, even with slightly higher insurance.
• Investment rate: if you keep renting, the money you don’t spend on notary fees and insurance can be invested.
• Property tax and its yearly revaluation: a cost specific to owners, compared with the much lower tenant home insurance.

The advantage of the buy-or-rent.net simulator is that you can vary taux_assurance while holding other parameters constant, and see the isolated impact of insurance on your decision.

7. Buy or rent example with changing taux_assurance

Simple profile:

• Maximum monthly housing budget: €1,600.
• Current rent: €1,250/month, with 2% yearly increase.
• Purchase project: €300,000 property, 25-year loan at 3.6%.
• Net investment return if renting: 3% per year.

7.1. Tenant scenario (rent + invest)

Difference between budget (€1,600) and rent (€1,250): €350/month available for investment at 3% net. Over 25 years, this regular investing can grow, using compound interest, to roughly €160,000–€180,000 (order of magnitude, ignoring inflation).

7.2. Buyer with insurance at 0.40%

• Total monthly payment ≈ €1,621 (slightly above budget, so tight).
• Total insurance cost ≈ €30,000.

Here, the buyer has no room left to invest on the side. The buy or rent comparison becomes less favourable to buying.

7.3. Buyer with insurance at 0.25%

• Total monthly payment ≈ €1,583.50.
• Total insurance cost ≈ €18,750.
• Monthly margin ≈ €16.50 compared with the €1,600 budget.

The insurance comparison shows that a better taux_assurance:

• Makes the buying project affordable within the same budget.
• Reduces the cost gap compared with the “rent + invest” strategy.

Depending on how long you stay in the property, future resale price, rent inflation and property market trends, the simulator result may tilt towards buying or renting. There is no one-size-fits-all answer.

8. Borrower insurance, refinancing and early repayment

In 2026, regulations in many markets allow you to:

• Switch insurance policies during the loan term (subject to equivalent coverage).
• Refinance to get a better loan rate and/or better insurance rate.

In a buy or rent simulation, you can approximate this by:

• Reducing the loan rate after a few years.
• Lowering taux_assurance for the remaining term.

You must also factor in potential prepayment penalties (up to 3% of remaining principal or six months of interest) and various fees, which all add to the overall cost of the “buy” option.

9. What to watch for in an insurance comparison 2026

• Advertised rate vs real cost: check whether the taux_assurance is applied to the initial principal or the declining balance.
• Exclusions and waiting periods: a cheaper policy may cover fewer risks.
• How premiums evolve: some contracts adjust premiums with age or inflation.
• Coverage split between co-borrowers: with two borrowers, the coverage share (e.g. 50/50 or 100/100) has a large impact on cost.

From a buy or rent perspective, a slightly more expensive but more protective policy can make sense to secure your home equity. That “safety value” is hard to express in a simulator, but it is financially relevant.

10. Conclusion: include insurance comparison in every buy or rent analysis

By 2026, focusing only on the mortgage interest rate and ignoring taux_assurance leads to underestimating the true cost of buying. For the same property, the difference in insurance cost alone can exceed €10,000 over the life of the loan. If you stay a tenant, that money can instead be invested at an attractive investment rate, potentially beating inflation.

The buy or rent decision depends on many factors: holding period, rent growth, inflation, property price trends, taxes, your risk profile and savings capacity. Insurance comparison is just one lever, but it’s a powerful and quantifiable one.
