This is fantastic software, i can't recommend it highly enough.
It's easy to pick up and get started, it's incredibly flexible to adapt to different situations and preferences, and it's also gorgeously designed and graceful in it's execution. There's a free 7-day trial, and a vibrant and helpful online forum of staff team and experienced users to answer any question you can come up with. There's also a fantastic set of introductory information and online video tutorials.
At it's heart, YNAB is a tool which helps you visualise and allocate how you *need* to, and how you *want* to spend your money. This is the budget part. It has some values embedded in it: decide where every penny is going; allocate for large expenses regularly; reduce here if you overspend there; live on last month's income. As part of this process you will be tracking how you actually *do* spend your money: this is the account-tracking part, complete with import from bank accounts, which will likely be familiar to users of other financial software packages. These two elements combined make for a very grounded and responsive personal finance system, which in slow-motion, looks like this: Money comes in. You budget it. You refer to those budget allocations (or not) when making spending decisions ~ but your spending is reflected back in the budget (via account tracking) ~ you review the budget and adjust if necessary. Repeat until it's second nature, any red numbers dimish, and your financial wellbeing flourishes!
These days, if i want to know what i can spend, i don't look in my purse, or check my account balances - i check my YNAB category balances. My current account might be hundreds in credit, but in YNAB I'm reminded of my plans for that money, and thus, whether or not to buy that iPad or this chocolate bar, or actually just pay the rent. This is a shift which happens slowly ~ but gone are the days of 'accidentally' being over-drawn or 'having to' put something on the credit card: now it's all allocated in advance. Additionally, if you're so inclined, YNAB can quietly help align your values with your spending, as it slowly becomes clear if there are gaps between your intentions and dreams, and the actuality of your day to day spending.
If you've got a decent income or even some surplus, you'll likely plug in your financial info and zoom off. But if you're broke, don't have a month's surplus, are behind with things, or in debt ~ well, you might need to bend a few of the YNAB 'rules' in the beginning, but i'd really encourage you to jump right in too! I've found YNAB invaluable at helping me get a grip on my finances, keep afloat, and even reduce debt, all while recession has been knocking the stuffing out of my income. I found YNAB paid for itself within a matter of weeks, and many times over in the past two years, not just in money saved and money spent more wisely, but also in peace of mind and a quietly growing financial confidence.
