I used a childminder about 10 years ago for ds. I paid £99 each week, which didn't leave much to take home after tax, ni, bus fares, "business clothes", lunches etc. At that time I thought childcare fees were extremely excessive.
Now I am a cm myself however, I find myself frequently unable to pay my bills on time. I charge between £3.25 and £4.00 per hour (cheaper rate for fulltimers because with parttime contracts you can never fill the unused hours).
I'm told as self-employment goes, childminding is one of those with the highest expenses. From our income Childminders have to pay:
Tax
Ofsted Annual Fee
National Insurance
Public Liability Insurance
House Insurance (need extra cover for equipment etc & limited choice of companies that offer insurance to Childminders)
Petrol, Business Car Insurance, maintenance/mot etc
Car seats appropriate to child's size/age & appropriate for cm's car (new law in May)
Extra toilet paper, tissues, wipes, washing powder
Exta cleaning products (had a poo covered carpet & wc yesterday to clean!)
Gloves, first aid materials (these now have dates on & have to be replaced regularly if not used)
Safety products, eg stair gate, cupboard locks
Fruit/nutritional snacks to cater for all diets
replacing damaged & lost toys/games/books/equipment
stationery (receipt books, files etc)
Arts & craft materials
Admission fees (eg toddler group)
Membership fees (NCMA, toy libraries etc)
Training courses/workshops
To name a few!
On top of this we can be given notice at any time when parent has lost job/changed job/moving house/child changing schools etc and our income is about to be reduced through no fault of our own.
While I'm being pessimistic about childminding when you look at how much a cm takes home and compare it with the hours worked:
actual childminding hours - mine currently 7:15 am - 6 pm
bookkeeping & tax returns
administration (correspondence, contracts, forms)
emails & website
preparation at start of day/cleaning up at end
cleaning toys & equipment
preparing meals & extra shopping
training/coursework (home assignments & at college)
interviews with prospective parents
You just have to love your job to work so long for so little!
