Weekly budgets based on (a variable) monthly budget
"I think the real problem here is dealing with the variable income. The envelope solution suggests the problem is that your brother doesn't have the discipline to avoid spending all his money immediately, but maybe that's not it. Maybe he could regulate his expenses just fine, but with such a variable income, he can't settle into a ""normal"" spending pattern. Without any savings, any budget would have to be based on the worst possible income for a month. This isn't a great: it means a poor quality of life. And what do you do with the extra money in the better-than-worst months? While it's easy to say ""plan for the worst, then when it's better, save that money"", that's just not going to happen. No one will want to live at their worst-case standard of living all the time. Someone would have to be a real miser to have the discipline to not use that extra money for something. You can say to save it for emergencies or unexpected events, but there's always a way to rationalize spending it. ""I'm a musician, so this new guitar is a necessary business expense!"" Or maybe the car is broken. Surely this is a necessary expense! But, do you buy a $1000 car or a $20000 car? There's always a way to rationalize what's necessary, but it doesn't change financial reality. With a highly variable income, he will need some cash saved up to fill in the bad months, which is replenished in the good months. For success, you need a reasonable plan for making that happen: one that includes provisions for spending it other than ""please try not to spend it"". I would suggest tracking income accurately for several months. Then you will have a real number (not a guess) of what an average month is. Then, you can budget on that. You will also have real numbers that allow you to calculate how long the bad stretches are, and thus determine how much cash reserve is necessary to make the odds of going broke in a bad period unlikely. Having that, you can make a budget based on average income, which should have some allowance for enjoying life. Of course initially the cash reserve doesn't exist, but knowing exactly what will happen when it does provides a good motivation for building the reserve rather than spending it today. Knowing that the budget includes rules for spending the reserves reduces the incentive to cheat. Of course, the eventual budget should also include provisions for long term savings for retirement, medical expenses, car maintenance, etc. You can do the envelope thing if that's helpful. The point here is to solve the problem of the variable income, so you can have an average income that doesn't result in a budget that delivers a soul crushing decrease in quality of living." If you know, approximately, the minimum he would get in a month, his budget should be planned based on this amount. In months where he gets more than this, the excess should be put aside. In really bad months where the income drops below the expected minimum, he can use the money put aside. After a year of putting money aside, he can plan to use and budget this for any other expenses. Try reading about budgeting.  Make a list of all income coming in and all expenses going out. Eliminate any unnecessary expenses and try to increase income, which could include a part-time second job.  Try to always put a portion of the income away as savings - try 10%, but if this is too hard to start with try saving at least 5% of the income. Developing self-discipline in his spending habits is a prerequisite for dealing with a (sometimes low) variable income.  While it might feel like a roller coaster ride going from boom to bust, develop steady frugal spending habits will ease a lot of that pressure.
Honestly? Literally anything else. The same way budgets have been done since the dawn of time. If you have a mandatory expense (livable wage because we're prioritizing human life over discretionary spending because ethics) you trim the fat from other areas to make it work. Plan all your needs and put priority based on need & urgency. New Habit: Rethink. Rethink. Rethink. whenever your going to buy something. rethink before going to buy. remember what is your priority one than that and will this affect on your plans. if that affect, than dont buy. Lets leave it to that habit, that will take care of your budget yar............. Do you plan a monthly budget at the beginning of each month?  This might seem counter-intuitive, but hear me out. Doing a budget is, of course, critically important for those who struggle with having enough money to last the month.  Having this written spending plan allows people struggling with finances to control their spending and funnel money into debt reduction or saving goals.  However, budgeting can also help those with the opposite problem. There are some, like you perhaps, that have enough income and live frugally enough that they don't have to budget.  Their money comes in, and they spend so little that the bank account grows automatically.  It sounds like a good problem to have, but your finances are still out of control, just in a different way.  Perhaps you are underspending simply because you don't know if you will have enough money to last or not. By making a spending plan, you set aside money each month for various categories in three broad areas: Since you have plenty of money coming in, generously fund these spending categories.  As long as you have money in the categories when you go to the store, you can feel comfortable splurging a little, because you know that your other categories are funded and the money is there to pay those other bills.  Create other categories, such as technology or home improvement, and when you need an app or have a home improvement project, you can confidently spend this money, as it has already been allocated for those purposes. If you are new to budgeting, software such as YNAB can make it much easier. My wife and I meet in the first few days of each month to create a budget for the coming month. During that meeting we reconcile any spending for the previous month and make sure the amount money in our accounts matches the amount of money in our budget record to the penny. (We use an excel spreadsheet, how you track it matters less than the need to track it and see how much you spent in each category during the previous month.)  After we have have reviewed the previous month's spending, we allocate money we made during that previous month to each of the categories. What categories you track and how granular you are is less important than regularly seeing how much you spend so that you can evaluate whether your spending is really matching your priorities. We keep a running total for each category so if we go over on groceries one month, then the following month we have to add more to bring the category back to black as well as enough for our anticipated needs in the coming month. If there is one category that we are consistently underestimating (or overestimating) we talk about why. If there are large purchases that we are planning in the coming month, or even in a few months, we talk about them, why we want them, and we talk about how much we're planning to spend. If we want a new TV or to go on a trip, we may start adding money to the category with no plans to spend in the coming month. The biggest benefit to this process has been that we don't make a lot of impulse purchases, or if we do, they are for small dollar amounts. The simple need to explain what I want and why means I have to put the thought into it myself, and I talk myself out of a lot of purchases during that train of thought. The time spent regularly evaluating what we get for our money has cut waste that wasn't really bringing much happiness. We still buy what we want, but we agree that we want it first. However, we would also like to include on our budget the actual cost of the furniture when we buy it. That would be double-counting.  When it's time to buy the new kit, just pay for it directly from savings and then deduct that amount from the Furniture Cash asset that you'd been adding to every month. Unless you are getting the loan from a loan shark, it is the most common case that each payment is applied to the interest accrued to date and the rest is applied towards reducing the principal.  So, assuming that fortnightly means 26 equally-spaced payments during the year, the interest accrued at the end of the first fortnight is $660,000 x (0.0575/26) = $1459.62 and so the principal is reduced by $2299.61 - $1459.62 = $839.99 For the next payment, the principal still owing at the beginning of that fortnight will be $660,000-$839.99 = $659,160.01 and the interest accrued will be $659,160.01 x (0.0575/26) = $1457.76 and so slightly more of the principal will be reduced than the $839.99 of the previous payment.  Lather, rinse, repeat until the loan is paid off which should occur at the end of 17.5 years (or after 455 biweekly payments). If the loan rate changes during this time (since you say that this is a variable-rate loan), the numbers quoted above will change too. And no, it is not the case that just %5.75 of the $2300 is interest, and the rest comes off the principle (sic)? Interest is computed on the principal amount still owed ($660,000 for starters and then decreasing fortnightly). not the loan payment amount. Edit  After playing around with a spreadsheet a bit, I found that if  payments are made every two weeks (14 days apart) rather than 26 equally spaced payments in one year as I used above, interest accrues at the rate of 5.75 x (14/365)% for the 14 days rather than at the rate of (5.75/26)% for the time between payments as I used above each 14 days, $2299.56 is paid as the biweekly mortgage payment instead of the $2299.61 stated by the OP, then 455 payments (slightly less than 17.5 calendar years when leap years are taken into account) will pay off the loan.  In fact, that 455-th payment should be reduced by 65 cents.  In view of rounding of fractional cents and the like, I doubt that it would be possible to have the last equal payment reduce the balance to exactly 0. The exact percentages depend on many things, not just location. For example, everyone needs food.  If you have a low income, the percentage of your income spent on food would be much higher than for someone that has a high income. Any budgeting guidelines that you find are just a starting point.  You need to look at your own income and expenses and come up with your own spending plan. Start by listing all of the necessities that you have to spend on.  For example, your basic necessities might be: Fund those categories, and any other fixed expenses that you have.  Whatever you have left is available for other things, such as: and anything else that you can think of to spend money on.  If you can save money on some of the necessities above, it will free up money on the discretionary categories below.   Because your income and priorities are different than everyone else, your budget will be different than everyone else, too.  If you are new to budgeting, you might find that the right budgeting software can make the task much easier.  YNAB, EveryDollar, or Mvelopes are three popular choices. The easiest way to get started on a budget is just to track where you spend your money. If you have set bills each month I would make a category for each of those to make sure you have enough to pay. You can try and split up the remaining income into categories but the easiest way to start is just to track your spending for a month or two. This gives you a birds eye view of what is actually realistic. Start with that total as your preliminary budget and then adjust as you go along to meet other financial goals. We use neobudget.com for tracking our income. Gail Vaz-Oxlade has a budget calculator here that shows how much of your monthly net income should be allocated where. She recommends 35% for housing, 15% for transportation, 25% for life, 15% for debt repayment, and 10% for savings. Some people spend more then they make and her budget sheet helps get things under control for those people. For someone like yourself who seems to have things under control, this budget sheet can be a guideline for you. Play with the percentages if you like, and keep your spending under 100%. I agree with the first poster- the first step is to measure your spending and put it down into raw numbers. Once you have the raw numbers, you will feel a natural inclination to improve on those numbers. Set yourself a daily target for cash / incidental expenses. It doesnt have to be a crazy target - just something you can achieve easily. Mark a 'tick' mark next to every day on the calendar that you meet that target (or spend less than the target). Gradually the momentum from the past few 'ticks' will automatically compel you to want to tick off the next day.  At the end of each week, lower the target a little. You'll find that when you start measuring your expenditure, you become more aware of how you might be wasting money. All too often we just go out and buy stuff we don't need without really thinking about it. Canada does not have a set date on which a (Federal) budget plan is unveiled. In 2011 it was June 6th. In 2012 it was March 29th and in 2013 it was 21st March. Calculate a weekly budget for yourself for all incidentals (i.e. shopping, movies, eating out, etc...) and take that amount out in cash each week. For example, if your budget is $75 then try to spend only that $75 on all the extra stuff you do doing the week. It'll make you hyper-conscious of where your money is going and how fast. You'll be surprised at how quickly little things like grabbing coffee in the morning can chip away at your funds. My guess:  they are giving you a constant number of days between when the bill is sent and when it is due.  Due dates are usually set either: same date each month IE the 3rd of each month. same day IE first thursday of the month. Note: due date might vary based on weekends. Number of days in the month - date on bill should be pretty constant if due date option #1 is being used.  Note how Feb dates were usually earlier, since it is a shorter month. You can take a shortcut and make a few cumulative transactions, maybe just estimate how much of your spending landed in each of your budget categories, but you will lose a lot of the value that you were building for yourself by tracking your spending during the earlier months. I reconcile my budget and categorize my spending on a monthly basis. It's always a chore to pull out the big stack of receipts and plow through them, but I've learned the value of having an accurate picture of where all my money went. There is no clean way to fake it. You can either take the time and reconcile your spending, or you can take a short cut. It probably renders your efforts to track everything from the beginning of the year invalid though. If you want to start over this month (as you did at the beginning of the year) that would probably be a cleaner way to reconcile things. Alternative solution with possibly better results: Use a 3rd party to transfer money between both of you. 2 Services you may want to look at: Rent share might be the best option. We are using it to split payment between 3 people in our unit. The owner is getting a single check that appears to be coming from all of us. The payment is automatic and goes through every month. I'm not sure if you as the owner could collect money electronically as opposed to receiving a check. It sounded like you didn't necessarily care about that though.
