This is kinda shocking when I do the math, as I have never done the math before..

4 horses & 1 mini

I feed bale & 1/4th a day and paying $7 a bale for alfa/grass mix in Los Lunas, NM ( It would be 6.50 but I pay my neighbor 50cents to deliver and stack) = $3500 a year approx
Trims every 6-8 weeks - $1050 a year
De-Wormers ( Buy Standard 1 year pack through horse.com ) $115 a year
Senior Feed in the winter and when horses are being used heavily ( About $600 a year )
Supplements - Scaled down, about $300 a year
Vet ( twice a year shots and check ups & floating ) $1000 a year ( haven't had any major medical issues )
And not including any tack or other supplies as I am done shopping for a year until I get my credit cards paid down..

Not including mortgage for my mini-ranch and electricity for well pump, lights , I pay about $6565 a year.. I don't have any children so I justify this in my budget as what I would pay for daycare if I had a child )
