Benefits calculators?

[BirdBrain85]

Assuming I enter my details correctly, can I expect the gov benefits calculators to be fairly accurate? Any experiences / knowledge greatly received! I'm expecting my first baby and trying to get my head around my entitlements.

I've found it not to be that accurate but entitled to is quite good.

As McDougal says the Entitled to ones are most accurate. I think I read on another forum that people have found the Gov. Uk and HMRC ones the least accurate !
Basically for a new baby you will get child benefit of £20.30 per week unless one of you earns over £50k.
For tax credits entitlement if your joint household income is over around £26k then you won't be entitled to any with one child. However if you will be paying out childcare then the threshold is quite a bit higher.
