10% of every checking deposit goes to savings. 1% of all expenses is added to savings, not including mortgage, taxes and insurance. Any money removed from savings is paid back with 5% interest.
I like to keep the checking account above $5000 because that gives me an easy three month cushion. My savings account is a bit higher than the checking and I don't have a mortgage or car tabs.
I have $0.00 credit card debt or a positive balance and just the normal gas, electric, water and phone/internet bills. Just finished paying off the doctor and hospital bills for the wife's cancer surgery.
It has been a couple of "tight" months for me but I am still on track financially.
The only thing hard about having a cushion is getting into the habit of saying no to yourself when it comes to buying anything that is not a necessity. When a deposit is made into the checking account you the decimal one place to the left and make out a transfer from checking to savings. You pay yourself just like you pay any other bill. It adds up fast and you start to like it after a year or so.
