Chart of Accounts

  A listing of all the accounts available in the data file. The chart of accounts consists of balance sheet accounts (assets, liabilities, stockholders' equity) and income statement accounts (revenues, expenses, gains, losses).

Commission

  The fee paid to a broker to buy or sell securities.

Commodity

  A commodity is something of value that is easily tradeable or sellable; for example, currencies, stocks, bonds, grain, copper, and oil are all commodities.

Common stock
Stock
Compounding

  The concept that the reinvested interest can later earn interest of its own (interest on interest). This is often referred to as compound interest.

Cost Basis

  Cost basis is the original cost of property, adjusted for various factors. Its primary use is for tax purposes. Factors that affect the cost basis include: stock splits, dividends, depreciation and return of capital distributions. Cost basis is used to determine the capital gain.

CSV

  Stands for Comma Separated Values. CSV files are used to store data in plain text. Each line of the file is a record and each record can be comprised of multiple fields separated by commas. CSV is one import format that &app; supports.

Dividends

  Dividends are cash payments a company makes to shareholders. The amount of this payment is usually determined as some amount of the profits of the company. Not all common stocks give dividends.

Equities

  Equities are investments in which the investor becomes part (or whole) owner in something.

Financial Transaction Services (FinTS)

  A banking protocol used by German banks. Developed by the German Central Banking Committee ZKA (Zentraler Kredit-Ausschuss). The standard is used only by German banks. Prior 2002, it was called Home Banking Computer Interface (HBCI). FinTS is one import format that &app; supports.

  Linux

    DConf since Gnome 3.0 dropped GConf

  MacOS

    Defaults. Use the command-line defaults(1) to modify prefs when GnuCash isn't running.

Home Computer Banking Interface (HBCI)

  A bank-independent online banking protocol used by German banks. Home Banking Computer Interface (HBCI) was developed by the German Central Banking Committee ZKA (Zentraler Kredit-Ausschuss). Since 2002, it has been called Financial Transaction Services (FinTS). HBCI is one import format that &app; supports.

  Financial Transaction Services (FinTS)
Interest

  What a borrower pays a lender for the use of their money. Normally, this is expressed in terms of a percentage of the principal per year. For example, a savings account with 1% interest will pay you $1 for every $100 you keep deposited per year.

Liability

  A liability is a debt or obligation that an individual or organization owes.

LibOFX

  An open source library for OFX. It was created by one of the &app; developers, originally to be the OFX interface for &app;.

  OFX
Liquidity

  A measure of how easily convertible an investment is to cash. Money in a savings account is very liquid, while money invested in a house has low liquidity because it takes time to sell a house.

Lot

  A lot is a means of grouping a commodity so that you later identify that the item bought in one transaction is the same as one sold in a different transaction. Lots are often implemented with stocks, where capital gain can depend on which item is being sold at a given time.

MT940

  A financial information standard defined by SWIFT and used by several European banks. It is also used internally in HBCI. Unfortunately, you can't download the MT940 standard, but some banks publish it on their websites. MT940 is one import format that &app; supports.

OFX

  The Open Financial eXchange format. This is a financial information exchange standard used by many institutions. OFX is one import format that &app; supports.

Price Database

  The price database contains a store of price quotes for stocks, mutual funds, and currencies.

Principal

  The original amount of money invested or borrowed.

QFX

  The Quicken Financial eXchange format is a proprietary financial information exchange standard promoted by Quicken and used by many institutions. QFX is one import format that &app; supports.

QIF

  The Quicken Interchange Format (QIF) is an open specification for reading and writing financial data to files. This is an older format that is still used by many institutions. QIF is one import format that &app; supports.

Realized Gain/Loss

  The difference between the purchase and selling prices of an investment at the time the investment is sold. Also known as Capital Gain/Loss. Before an investment is sold, the difference in value is referred to as Unrealized Gain/Loss.

Reconciliation

  Reconciliation is a verification process in which the user compares their records with those of the financial institution to ensure that the records in each system agree at some particular point in time. During reconciliation, the user checks individual transactions in their file against the institution's statement; upon completion, the reported balances of the institution and the reconciled account will match at that point in the register.

Return

  The total income plus capital gains or losses of an investment.

  Yield
Reversing Transaction

  In formal accounting, a transaction is never deleted. Therefore, when a mistake is made, the original transaction remains in the ledger, and a transaction is added to the ledger that reverses the original. This reversing transaction duplicates the original transaction, but with debit and credit amounts reversed. This removes the effect of the erroneous transaction from the books. After entering the reversing transaction, a corrected transaction can then be entered. Reversing transactions are not commonly used in personal accounting.

Risk

  The probability that the return on investment is different from what was expected. Investments are often grouped on a scale from low risk (e.g., savings accounts or government bonds) to high risk (e.g., common stocks or junk bonds). As a general rule of thumb, the higher the risk, the higher the possible return.

Scheduled Transaction

  Scheduled transactions provide a framework for remembering information about transactions that are set to occur in the future, either once or periodically.

  Yield
Scheme

  Scheme is a functional programming language based on a dialect of LISP. Reports in &app; use the Scheme programming language; thus, users wishing to customize reports must write Scheme.

Shareholder

  A shareholder is a person who holds common stock in a company.

Split

  A split, or Ledger Entry, is the fundamental accounting unit. Each split consists of an amount, the value of that amount expressed in a (possibly) different currency, a Memo, a pointer to the parent Transaction, a pointer to the debited Account, a reconciled flag and timestamp, an action field, and a key-value frame which can store arbitrary data.

Stock

  A security that represents a certain fractional ownership of a company. This is what you buy when you buy stock in a company on the open market. This is also sometimes known as capital stock, or common stock.

Stock split

  Occurs when a company offers to issue some additional multiple of shares for each existing stock. For example, a 2 for 1 stock split means that if you own 100 shares of a stock, you will receive an additional 100 shares at no cost to you. The unit price of the shares will usually be adjusted so there is no net change in the value, so in this example the price per share will be halved. Note that such transactions affect the cost basis per share owned.

Transaction

  A transaction consists of a date, a description, an ID number, a list of two or more splits, and a key-value frame. Transactions embody the notion of "double entry" accounting.

Unrealized Gain/Loss

  Unrealized gain or loss is the difference in value between a purchase price and the current value of a given asset. These gains remain unrealized until the asset is sold, at which point they become Realized gains or losses.

  Capital Gain/Loss
  Realized Gain/Loss
Valuation

  The process of determining the market value or the price the investment would sell at in a reasonable time frame.

XML

  The eXtensible Markup Language is an international markup standard. &app; stores its data by default in an XML data structure.

Yield

  A measure of the amount of money you earn from an investment (i.e., how much income you receive from the investment). Typically, this is reported as a percentage of the principal amount. Yield does not include capital gains or losses (see Return). For example, a stock that sells for $100 and gives $2 in dividends per year has a yield of 2%.
