# Personal Finance

I manage my money using plain-text accounting (specifically, hledger; though the choice of tool is unimportant), following a YNABish approach. The four YNAB rules are:

1. Give every dollar a job: my money is split into named categories, I have no “general savings”.
2. Embrace your true expenses: large expenses (like a rental deposit) are planned and allocated for in advance, as a regular monthly contribution.
3. Roll with the punches: if things aren’t working out, I adjust the plan rather than lie to myself.
4. Age your money: I save more of each regular expense (rent, travel, etc) than I spend in a given period, so I gradually build up a buffer.

Rather than importing transactions from my bank or something, I enter all data manually. This may sound tedious, but I feel that the awareness I get from doing so is worth it.

Why track my finances at all?

• Makes me more conscious of my spending.
• Lets me see how my spending has changed over time.
• Lets me plan for the future with some degree of confidence.

This memo is concerned with my mechanism for implementing this approach. It could serve as a starting point for your financial planning; but working out what your savings categories are and how to allocate your income to them requires introspection.

## Data Files

My hledger data files (the “journal files”) are shared with syncthing, so I can add transactions from any machine.

I have one journal for each calendar year:

• current.journal, the journal for the current year.
• $YEAR.journal, is the journal for a previous year. I also have two files which all my journals include: • commodities, a list of all commodities (currencies, cryptocurrencies, funds) I deal with. • prices, end-of-day exchange rates for all of my commodities. ## Chart of Accounts Accounts are broken up into five broad categories: • assets: money I have or am owed. • equity: used to start off the ledger for the year. • expenses: money I have spent. • income: money I have received. • liabilities: money I owe. Then assets is further subdivided into: • cash: easily liquidated assets. • investments: brokerage accounts. • pension: employer-managed pension funds. • receivable: money I am owed. The set of accounts I use is fairly stable: sometimes I’ll add one, or one will cease to be useful, but that’s a rare event. Here are all the regular accounts, which are mostly self-explanatory: • assets • cash • paypal • petty • hand Physical cash, in my wallet • budgeted … which was withdrawn from my bank account • unbudgeted … which was a gift • home Physical cash, not in my wallet • nationwide • flexdirect • goal Subaccounts for specific future expenses, like renewing my passport; money added when I am paid • pending Subaccounts for money put aside for transactions which have not cleared yet • saved Savings; money added when I am paid • discretionary • food • gift • graze Subscription to Graze • health • household • insurance • invest • food • phone • rent • tea • travel • utilities • starling • float Cash which can be withdrawn • patreon Savings for Patreon subscriptions (charged in USD) • web Savings for AWS, domain names, and web hosting (all charged in foreign currencies) • investments • cavendish • coinbase • fundingcircle • pension • civilservice • receivable • deposit The deposit on my flat • equity • expenses • adjustment See Balance Correction • beeminder I use Beeminder to enforce some habits • books • clothing • fees Subaccounts for various things • food • fun • gift • health • household • insurance • music • other • phone • rent • tax • council • income • ni National Insurance • tech • travel • utilities • electricity • internet • water • web • income • adjustment See Balance Correction • amex To track cashback offers and similar • donation • gift • interest • job • liabilities • creditcard • amex My American Express credit card • loan • slc My student loan • payable Subaccounts for people I owe money to An account name is the path to it through the tree, separated by colons. For example, assets:cash, or expenses:utilities:electricity. Many of these accounts do not correspond to any real-world bank or brokerage account, they are used to track the flow of money in more detail than if I just recorded which bank accounts things came from or went to. Money (and other commodities) is only stored in leaf accounts. ## Financial Institutions I have two bank accounts, three investment accounts, and a credit card. For bank accounts I use: • Nationwide, my main bank account. My pay goes here, almost all of my expenses come out of here. • Starling, my backup account. I keep a small amount of money in here to withdraw for if my Santander debit card is not working (Santander is Visa, Starling is Mastercard). I also use it for all my foreign currency transactions, as Starling doesn’t charge currency conversion fees. For investment accounts I use: • Cavendish Online, who are as far as I can tell just a front-end to services provided by Fidelity (who do not themselves offer accounts directly), and who provide a reasonable selection of funds for my stocks & shares ISA. • Coinbase, who offer a few different cryptocurrencies. I have very little in crypto, because it’s so volatile. • Funding Circle, who provide my innovative finance ISA. For a credit card I use an American Express cashback card. There is a small annual fee (£25), but by using it for all the transactions I can, the cashback more than covers that. Most of the time I am dealing with American Express and Santander, only rarely do I need to touch the others. ## Transactions A transaction has a date, a payee, and a list of postings: 2018-01-01 Payee account1 £amount1 account2 £amount2 ... The amounts must sum to zero, which means that the transaction is balanced. hledger allows transactions to be marked with a ! or a *. The traditional meaning of these is “pending” and “cleared”. I use ! slightly differently. I use it for transactions which are just an artefact of the way I track my finances, which don’t involve any balance changes to a real-world account. For example, moving money between different types of savings: 2019-01-23 ! Allocation assets:cash:santander:current:saved:food £25.00 assets:cash:santander:current:saved:discretionary I use * as normal, although I usually only consider cash transactions “cleared” after I check that the cash in my wallet matches what hledger thinks it should be. ### Income Income is recorded as the pre-tax amount coming from income:$source, and is split across saved:*, expenses:tax:*, and liabilities:*. All amounts are included.

This is because it’s useful to have cash on hand without necessarily having decided up front what it’s for, but it’s also good to bound the amount of unallocated money I have. 2019-01-25 * Withdraw assets:cash:petty:hand:budgeted £10.00 assets:cash:starling:float Cash can also be withdrawn in a foreign currency, which will have an exchange rate and may impose an additional fee: 2018-05-11 Withdraw assets:cash:petty:hand:budgeted 10000 JPY @@ £70.41 expenses:fees:currency £1.99 assets:cash:starling:float “£” is the only commodity I give a symbolic name. ### Expenses (bank account) There are three types of expenses: expenses from my bank account, expenses on my credit card, and cash expenses. The former are straightforward: 2019-01-06 * Graze expenses:food £3.79 assets:cash:santander:current:saved:graze Foreign currency expenses are recorded like so: 2019-01-01 * Linode expenses:web 20.00 USD @@ £15.77 assets:cash:starling:web Sometimes I’ll add a transaction note, which comes after a vertical bar: 2019-01-06 * Steam | 1644277325735538856 expenses:fun £9.29 liabilities:creditcard:amex ### Expenses (cash) Cash expenses require an adjustment to the appropriate budget category, transferring money back to the float to represent that that money has been allocated and spent: 2019-01-25 * Post Office expenses:other £1.01 assets:cash:petty:hand:budgeted 2019-01-25 !

The exchange rate is kind of arbitrary, but something reasonably close to the then-current exchange rate should be used. ### Expenses (credit card) I model expenses on my credit card much like cash expenses. When I pay for something on my credit card I add a transaction from liabilities to track the debt and remove the money from the budget category: 2019-01-01 * Morrisons expenses:household £3.00 expenses:food £15.21 liabilities:creditcard:amex -£18.21 2019-01-01 !

After the direct debit comes out there should be no balance remaining on the card. ### Reimbursements Reimbursements are much like income, but are generally untaxed. Income comes from some reimbursement account and is put in some savings account: 2018-01-04 * Pusher assets:cash:santander:current:goal:deposit £186.00 assets:receivable:pusher As with income, the reimbursement could be split over multiple savings accounts. ## Predicting the Future Predicting the future can be the downfall of an otherwise-sound financial plan. Always be pessimistic! Only include income which you are certain you will get (barring some extreme change in your life circumstances); but include any expenses you can think of, even if they are unlikely. If you can be pessimistic and still have some wiggle room in your plan, then you are probably in a good place. ### Budgeting By a “budget” I mean an allocation of current money to expense categories and new money to savings categories. I budget on a monthly basis. Firstly, my monthly expenses: ~ every 1st day of month (assets:cash:starling:patreon) -£3.00 ; HPPodcraft (assets:cash:starling:web) -£45.00 ; Linode / OVH / Moniker (estimate) (assets:cash:nationwide:flexdirect:saved:food) -£185.00 ; Monthly food (assets:cash:nationwide:flexdirect:saved:invest) -£100.00 ; Cavendish direct debit (assets:cash:nationwide:flexdirect:saved:rent) -£82.00 ; Council tax ~ every 15th day of month (assets:cash:nationwide:flexdirect:saved:rent) -£1300.00 ; Haart ~ every 16th day of month (assets:cash:nationwide:flexdirect:saved:insurance) -£11.49 ; Homelet ~ every 28th day of month (assets:cash:nationwide:flexdirect:saved:graze) -£15.16 ; Graze (assets:cash:nationwide:flexdirect:saved:phone) -£13.00 ; EE (assets:cash:nationwide:flexdirect:saved:utilities) -£25.00 ; TalkTalk (assets:cash:nationwide:flexdirect:saved:utilities) -£50.00 ; EDF Energy Now, my monthly income: ~ every 30th day of month from 2019-03-30 assets:cash:nationwide:flexdirect:goal:oculus_rift £75.00 assets:cash:nationwide:flexdirect:pending:starling:web £45.00 assets:cash:nationwide:flexdirect:pending:starling:patreon £3.00 assets:cash:nationwide:flexdirect:saved:discretionary £79.34 ;= £500.00 assets:cash:nationwide:flexdirect:saved:food £225.00 ;= £1000.00 assets:cash:nationwide:flexdirect:saved:gift £0.00 ;= £150.00 assets:cash:nationwide:flexdirect:saved:graze £15.16 ;= £50.00 assets:cash:nationwide:flexdirect:saved:health £0.00 ;= £50.00 assets:cash:nationwide:flexdirect:saved:household £75.00 ;= £300.00 assets:cash:nationwide:flexdirect:saved:insurance £11.49 ;= £50.00 assets:cash:nationwide:flexdirect:saved:invest £100.00 assets:cash:nationwide:flexdirect:saved:phone £13.00 ;= £50.00 assets:cash:nationwide:flexdirect:saved:rent £1800.00 ;= £4200.00 assets:cash:nationwide:flexdirect:saved:tea £15.00 ;= £30.00 assets:cash:nationwide:flexdirect:saved:travel £15.00 ;= £50.00 assets:cash:nationwide:flexdirect:saved:utilities £125.00 ;= £250.00 expenses:tax:income £807.60 expenses:tax:ni £387.48 liabilities:loan:slc £246.00 assets:pension:civilservice £232.76 income:job -£4270.83 assets:pension:civilservice £943.85 income:job -£943.85 The month-to-month allocation of money will vary a little. ### Forecasting In its simplest form, forecasting is just applying your budget into the future. I plan for each calendar year, so I look ahead to the end of December to see that everything is working out. However, expected future events can be added to the forecast too: ; Dentist ~ 2018-03-20 expenses:health £20.60 assets:cash:santander:current:saved:health It is essential that none of my savings accounts dip below zero, and ideally their balance should be increasing every month, due to saving extra. When I have enough of a buffer, I will remove this extra allocation (just maintaining the current balance) and put the extra money to some other use. In my mind, it doesn’t really make sense to talk about budgeting and forecasting as separate entities. A budget only makes sense if it serves your future purposes, so it’s not as simple as looking at what you have vs. looking into the future. I try to think of it like this instead: budgeting is the allocation (which may involve planning ahead) whereas forecasting is looking at how your allocation (plus any other expected transactions) changes your financial situation over time. ## Maintenance In addition to simply recording transactions, there is some bookkeeping I do occasionally, to keep my records easy to process. ### Once every so often Every so often (every week or two) I check my various financial statements and reconcile transactions in the journal: 1. For every transaction in the statement, find the corresponding journal transaction and mark it. • If there are transactions missing from the journal, add and mark them. • If there are transactions missing from the statement, the institution is being slow; reconcile as they come in over the next few days. • If all transactions have cleared but the balance is not what is expected, either figure out what happened or add transactions to adjust (see Balance Correction). 2. Check the balance in my wallet and mark all hand transactions. • If the wallet balance is below the hand balance, add a transaction to adjust (see Balance Correction). ### End of Year 1. Reconcile transactions. 2. Rename the current journal file from “current.journal” to “$YEAR.journal”.
3. Identify financial goals for the upcoming year.
4. Create a new “current.journal” for the upcoming year with budget and forecast transactions.
5. Initialise all accounts on the first of January by transferring from equity.

The budget created in (4) will depend on the goals identified in (3). Here’s an example of a (5) transaction setting up the starting balances:

### Balance Correction

Sometimes I get things wrong. I will make a mistake recording a transaction, and a mistake reading that same transaction from my bank statement at the end of the month. Because it takes time for transactions to appear in my online banking, and even then they often appear out-of-order, just comparing my hledger end-of-month balances with what my bank thinks they are is not easy.

Tracking down the original error is usually far more trouble than it’s worth.

If I suspect I have made a mistake (or just want to verify that I haven’t), I avoid spending money from my bank account for at least one working week. A simple way to achieve this is to withdraw a bunch of money and just use cash for that week.

After a week, every uncleared transaction should really be in my online banking, so I can reconcile, and insert a balance adjustment transaction if I need to:
