Budgeting and Spending Cash

(Disclosure — this post is about budgeting and mentions my Android app for doing the same, so take that as you will.)

How do you budget your spending?

Apparently my way of doing it is strange –here’s what I do. I know my annual salary, and I know my paycheck amounts (after taxes), and all of the other relevant income numbers. I also know my recurring expenses — the mortgage, food, utilities, day care, and so on. (I break those into needs and wants as well, but it’s not really important for this post.) For the sake of simplicity, you can assume that I include my savings, Roth IRA contributions, etc, in the tally of recurring ‘expenses’.

When I subtract my recurring expenses from my income, I get my discretionary income. I have it in annual, monthly, weekly, and per-paycheck increments.

How do I budget that part out? Apparently the normal way to do that is to plan how much to spend on this and that, and then try to stick with it. Track expenses in each category meticulously, make sure everything adds up. That’s too much overhead, and I’ll never stick to it. Instead, I say to myself, “Self, you’ve got $200 to spend and you’ve got to make it last a week. If you run out before then, you’re out of luck.” The relevant numbers, then, are how much time I have left in my budget period, and how much money I have to cover it. I trust myself to look at my wallet and, based on those numbers, decide whether I can afford to go out to eat tonight, or order that book or electronic gizmo.

That worked when I spent most of my money in person. However, these days I spend most of my discretionary funds online, via a credit card. I’m not keen to use something like Mint.com (imagine if someone hacked Mint.com — they’d have all of your login information for all of your accounts — a single point of failure), and I don’t think it would let me do what I need to do anyway. One option is to have an amount of cash equal to my weekly budget, and set any aside that I’ve spent online. Then I could take it back out and supplement it from my bank account when my budget rolled over. That’s what I did for a while.

A second option is to keep a little notebook and tally expenses. I think that’s actually a great option, but I don’t like carrying a notebook and pen with me. I would prefer not to carry anything extra.

However, I am always carrying my Android phone. As such, I decided to write a little program for it that tracks my monthly and weekly budgets, and allows me to subtract from them by spending an arbitrary amount. On the weekly and monthly budget reset dates it resets and optionally rolls over any remaining amounts or amounts over-budget (as negative amounts).

So far it doesn’t seem to be a very popular app. It was suggested to me that that was because nobody budgets this way. Is it so strange? How do you budget?

SpendingCash Posted to the Android Market

I posted my first for-pay app to the Android Market yesterday. It’s something I wrote because I couldn’t find anything like it. It’s very simple, and the point of it is to simply track one’s spending within weekly and monthly budgets.

I have tracked, using a spreadsheet, my disposable income for at least five years. I used to take out my weekly budget in cash every week, but now I work at home and so most of my spending is online via credit cards. I wanted something that would let me track how much of my budget I had left and tell me how long I had to stretch that money.

My first thought was to produce some sort of thin, credit-card-sized device that would do it, but I realized that would be too time consuming and expensive. Instead, I wrote this simple Android app. After all, I pretty much have my phone with me at all times, so I’d never be far from entering my expenditures.

I hope that there are people out there that have a similar need and are willing to pay $1 to have that need met. The first 24 hours have not been promising, but in the end I have an app that I like, and I guess if people eventually try it and decide they like it as well, it’ll be a little extra spending cash for me.

I made a simple site for the app: SpendingCash

Would this sort of thing interest you? Why or why not? Do you think it’s worth $1?

JustSit 0.2.2 is Out

Just uploaded, you can download the APK here. I think I’m going to release this one on the Android Market as well.

I fixed an outstanding screen rotation bug, made it so that vibrate mode applies to both the bell and the ringtone, and upgraded to the Android 1.5 (Cupcake) API.

Just Sit

As a learning exercise, and because it was something I wanted to have, I created a simple meditation timer application for Android called JustSit.

The name is derived from a quote attributed to Zen Master Unmon:

If you walk, just walk, if you sit, just sit, but whatever you do, don’t wobble.

This quote is a tongue-in-cheek admonition to focus on the task at hand. There are plenty of timers for Android already, but this one does something special — it optionally helps to shut out the outside world by silencing the phone’s ringtone and/or turning off all of the network connections.

There are still a few things I want to add to the application, namely, options for sounds marking the beginning and end of the meditation period (currently mandatory), and options for vibrating notifications or no notifications. I’d also like to allow users to select the sounds to be used — currently they are hard-coded. Finally, it would be nice to allow people to save various profiles and timings. Nonetheless, at this point I find the application perfectly useful for its intended purpose.

For now, I’m not putting it on the Android Market. I don’t feel like it’s been tested enough to withstand the brutal onslaught of the Market users, and I am waiting to charge a small fee in order to recover my developer registration. The application will always remain open source, and will always be available for free on the project website. However, the majority of users will neither know how to nor want to download and install the app from there, so I’ll make it available with the aforementioned ‘convenience fee’ from the Market. The ability to charge for apps is not currently available on the market, and one is not allowed to charge later for an app that is initially given away for free. I may post it to other Android application sites.

Please let me know if you try this and find it useful, and submit any feature requests or bug reports on the project Issues page.
