There has been a lot written lately about how much it would cost if stay at home mums were to charge their time out at an hourly rate. The figure ranged between £45,000 to £65,000 or $79,000 to $100,000. That was for a stay-at-home mum. If you take into account pay inequality, the so called gender-gap, you can add nearly 20% on to that for a stay-at-home dad. Of course there shouldn’t be a gender gap but the statistics don’t lie. You need to also remember that a lot of these statistics are are compiled by men who are naturally inclined to add an extra 20% when measuring things!
