Our Monthly Budget in Vancouver

We spend more than we make per month at the moment. We will try correct this by the end of the year. Per month the least we make is $4000 after taxes, the most we make is $5300 after taxes. At the beginning of May I will break down what we make each month vs how much we spend each month. In terms of how much we spend? We spend 4400 to 4600 per month. How do we compensate for the difference I will show you when I begin our monthly budget starting in May.
