A lot of extra information can be found Googling for "Cost of living in The Netherlands"
Numbeo gives a detailed list of sample items (note: no research data, just user contributed info). They claim:

Some remarks from ExpatArrivals:
Expats living in the Netherlands must purchase health insurance from a Dutch provider. Costs vary depending on the package chosen but can range from around 100 to 350 EUR and up.
Liability insurance, which is usually included in household insurance, is also a must. If a person, their child or their dog damages anybody else’s property they will be held responsible and will be expected to have this
Tuition at local schools is free, but international schools are expensive, and can easily cost 15,000 EUR per year.
In Eindhoven, there seems to be only one international school. This is what they say about their tuition:
- Primary school fees are only (a minimum of) €450. Formally speaking this is a voluntary contribution, but you can't really not pay this.
- Secondary schools are a different story: That's €6500 and not voluntary.
Expatistan has a 'Cost of living index' which shows you that you are 17% cheaper of in Eindhoven than in Amsterdam ;-)
Since many households live on one salary, and your kids are still in primary school, your number sounds 'doable'. I would hesitate if they were in secondary school.
But it's your decision (also based on non-financial arguments). Make a list of monthly expenses and decide based on that.
