I am actually using it for vet bill savings, but it works.
This chart inspired me to calculate what we spend on our pets each year. I was able to create a sinking fund and this chart really helps me confirm we are on track for the year to pay cash and not use a card like we have in the past.
When my indoor cat accidentally got out, he was badly injured (still unknown by what). The vet visits, overnight stays, oxygen, everything!! Added up to nearly $3,000. I did not have that money on me at all and had to ask my friends to donate anything to help me pay it off (I couldn't be accepted for a loan as I did not have any credit). I paid as much as I could, my friends donated, and my mother ended up paying the rest! Although none of them wanted to be paid back, I was so appreciative and wanted to. This chart helped me to pay every single person back (except my mum, hers was the biggest and I am still getting there!). I marked the lines (individual goals) with the persons name so when I reached it, I would pay them back instantly!
