<prompt> Human: My wife and I get paid biweekly as opposed to monthly. For the last few years, we have done a monthly budget based on the number of checks we would receive in that given month. Because of this, the amount of money would spike every third month when one of us got an extra check. Over time, I felt like we were being more wasteful in the months with the extra check since it felt like we were that much richer. This month, I started a new system where income is determined by calculating I365D, where I is combined annual take-home and D is the number of days in the month. This way, the extra checks are dispersed more uniformly and the months that should require extra expenses get them. I was wondering if anybody else used this approach or had a better way with dealing with biweekly income.  <response>: No need to get that complicated. Pay yourself first. Then ideally use whats left of your first check towards rentmortgage and your second towards other expenses. If you have leftover money at the end if the month, move it to savings.
