Days of Buffering History Lookup (Best Option)

For those that use the Days of Buffering History what setting do you use?

I currently have mine set at 3 Months.

  • One year.

    I feel that one year gives me the best sense of how far my current liquidity will carry me.  One year or 12 months of my annual expenses includes my lumpy expenses in categories like charity, gifting, clothing, entertainment, and annual car insurance. A big one-off expense that doesn't happen every year will skew the numbers, obviously, but in the last six years of YNABing, I have had at least one BIG, humongous, unrelated, one-off expense in each year, so....the skewed buffer number is actually much closer to reality than the non-skewed number would be.

    • HappyDance That makes a lot of sense so you can get an idea of how your money looks over the past year.  Yes, it always seems there is one large expense or one large deposit every year to skew the numbers.

  • One year. Anything else misleadingly inflates the metric by ignoring recurring True Expenses outside the window. I have some recurring obligations less frequent than yearly, but they are relatively negligible.

    • dakinemaui Yeah I have noticed that when I do all or less than a year it doesn't seem as accurate.

  • There are no good options, because large expenses that don't match up with the timescale will over- or under-weigh the average spending.

    • nolesrule Still, the likelihood of a larger recurring expense outside the yearly window is less than the other choices for most people.

      Granted, the chance of a larger one-off being in the yearly window is larger than that of the smaller window, but the probability of larger one-offs is also lower. Conditional probability says yearly unless you actually know there's a one-off already in the window.

      Honestly, I just divide my Income Replacement category by my monthly income. I think that's a better metric anyway.

  • I thought mine was set at 6 months and I just went in to check, and it's a year.  Right now (after big tax bill) it's 236.  6 months makes it 218 and 3 months makes it 180.  Yep, sticking with 1 year for sure!

    • Annieland HAHA sounds like one year makes you look better :)

      I think I will be putting mine at one year for now.  I like how it says average daily outflow. I want to get this number down next year.

      VoltaicShock oh gosh, I almost NEVER look at that number!  Just don’t look! It is what it is.

    • Annieland Yeah wish I had not looked at that number.  Now my goal is to get it as low as possible.

    Why?

    Your income is what it is. Spending less on "living" now allows more to be put toward retirement/investing... which is also seen as spending -- increasing that metric. Minimizing that metric should not be a priority in my view. 

    (I am assuming retirement/investment accounts are not part of the budget, which is recommended practice.)

    • dakinemaui Sorry I meant I want to get the DOB number up and the average daily outflow down (it was one of those years so it's higher than I like right now)

  • I couldn't remember what setting I had mine on. My DOB was 392. I opened up the settings and it was set on "All". Changed it to 1 year and now it's 531.

      Ok my All is 298.  Not crazy higher than my current 236 and usual 260-280.  I still ain't looking at avg daily spend cuz I know it's high and only went higher :(.

  • There's a $146/day difference between the setting that returns my highest and lowest DOBs.

    Keep in mind I keep my taxable investments on budget and use a category for the fluctuations (not TBB).

    My car contributes $10.42/day to my average daily spend under ALL, and $0/day for any other settings. I've had the car for a little over 5 years, but less than the amount of time I've been using YNAB. The actual effect on my spend/day from that single transaction should be $13.16.

  • I'm set at 1 year as well.  I agree that a consideration is whether there have been any changes in your income or spending patterns.  For example, my income at the job that I was forced to leave in 2017 was much higher than any job that I have had since, so the last 12 months is much more reflective of current income and spending.
