Save yourself some pain: Flush your brain from the "debit" and "credit" terminology.
Your have accounts. Period. All accounts are treated the same from the calculation point of view, that is, amounts get "posted" to them. Think: the number gets added to the balance at that date. The balance is simply the sum of all postings to that account. It doesn't matter which type of account it is. The double-entry idea is that the sum of all postings on a transaction must equal zero. It's a simple constraint. So those equations become much simpler: The sum of postings of each transaction = 0 Therefore, the sum of all postings = 0 And finally, even if you group the postings in arbitrary ways, the sum of all of them still = 0 Now, you can label accounts with one of five categories: Assets, Liabilities, Income, Expenses, Equity. If "Assets" stands for "the sum of all postings labeled with 'Asset'", these are just subgroups of all postings. Therefore, Assets + Liabilities + Equity + Income + Expenses = 0 If you define Equity' = (Equity + Income + Expenses), you obtain Assets + Liabilities + Equity' = 0 If you render a detail of the balances for these accounts, this is called a "balance sheet." If you render the detail of just the (Income + Expenses) accounts, this is called an "income statement." In this worldview, the balance of these accounts has a "usual" or "normal" sign, e.g., an Asset is usually positive, Liabilities will be negative. Income will be normally negative (it counts the dollar equivalent of work you gave away in exchange for an asset), Expenses will be positive (they count the dollar equivalent of goods and services you obtained in exchange for something you gave). The problem - and the genesis for all this credits & debits craziness - is that one doesn't usually talk about their credit card or mortgage balance using a negative number. All accounts are talked about using a positive variant. "I have a $100,000 mortgage" means "I owe $100,000" which really is the same as "I have -$100,000" (the latter view is how Ledger sees it). Accountants and people talk about positive amounts. Log into your bank website and check your balance: it'll be a positive number, yet, that's something you owe. For Ledger, that's a negative number. This is why in regular accounting people talk about "a debit account" or a "credit account". And then you get sentences like "debiting from a credit account"; and while you can train yourself and reason these things out, do this for a few hours while trying to figure out where the 1c off-balance amount comes from in a large book and your mind explodes. Anyhow, if you define the always-positive variants of those accounts as the symbols Assets+, Liabilities+, Equity+, Income+, Expenses+, etc. now you get the equations you're talking about: Assets+ = Liabilities+ + Equity+ We don't need this. Free yourself. Just learn this once and for all to work with Ledger and you're golden: - Assets usually has a positive balance - Liabilities usually has a negative balance - Equity usually has a negative balance - Income usually has a negative balance - Expenses usually has a positive balance That's all you have to know. Now you can just treat all accounts the same. Done! The last thing is: If you read an accounting text, you need to keep this in mind. But once you do understand the above... honestly everything becomes ridiculously simpler. (I hope you had an ah-ah! moment a some point reading the above. I hope this helps.)
