State pension calculator works out how much you are due in retirement

While it will cost people to make voluntary contributions now, it could add up to thousands of pounds when someone retires.

It’s also important to make sure a common Child Benefit mistake doesn’t affect your state pension entitlement.

Britons are being warned to take out extra care when it comes to filling out Child Benefit forms as it could destroy their entitlement to the state pension.

Some 200,000 parents apply for Child Benefit in the wrong parent’s name every year which could cost them their full state pension when they retire as they won’t have enough NI contributions.
