My husband was a teacher (school closed down - he's currently job hunting), and I am a SAHM. He worked for a very small school, so he made less than $24,000 a year. We live in a major city in NC, and were able to live off his one income comfortably by our standards.
What we do to save money:
We have a mortgage on our house, but other than that we have no debt. Our two cars do not have payments on them. It's cheapest to buy them used.
Internet phone for $14 a month
Food budget of $50-70 a week for three (soon to be four)
go out to eat or to the movie theater. Instead, we try to find free activities, and spend a lot of time enjoying home.
If we want to watch a movie, we either rent it for free from the library, or we get them for $1 through Redbox at the local grocery store.
We are very blessed with our car and home insurance - we are able to get it through USAA since my grandfather was formerly in the military. They have incredible rates.
We don't have health insurance.
We make any gifts or cards given to relatives.
We save in advance for Christmas and our dd's birthday, but our celebrations are still very modest.
We don't buy new clothes unless there is a reason to replace an item we already have.
I make all our meals from scratch, and we buy some food items in bulk from a nearby health food store.
For dd, I nursed exclusively until she wanted to try food at 10 months.
We made her baby food instead of buying it at the store.
We used cloth diapers (prefolds and covers) and cloth wipes.
We just live simply. Thankfully as far as furnishing and home items go, we were extremely blessed by the generosity of family and friends when we married three years ago. The only thing we didn't have when we moved into our house was a washer and dryer. We found a very used, old, beat up set for $25. Most people coming into our house have no idea that we are able to live on one small income. It is very doable - it just takes hard work and willingness to find new ways or alternatives to doing things. It can be difficult at times to not always be able to have what we want or do what we want, but we really do love our life and are thankful for it
