Accounts vs. Envelopes
Understanding the difference between accounts and envelopes.
Overview
Accounts and envelopes are the two fundamental organizing structures in Principal Plan. They track different aspects of the same money. Understanding the difference makes the rest of the application easier to use.
Accounts represent where your money physically lives -- a checking account, a credit card, or cash in your wallet.
Envelopes represent what your money is for -- rent, groceries, savings, or entertainment.
Most day-to-day transactions appear in both views. Transfers can appear only in the account view or only in the envelope view, depending on whether you are moving money between real financial accounts or reallocating money between budget categories.
Key Differences
| Accounts | Envelopes | |
|---|---|---|
| Represents | A real-world financial container (bank, wallet, card) | A virtual budget category (purpose, goal) |
| Types | 20 types: Checking, Savings, Credit Card, Cash, E-Cash, Investment, Group, Loan, Mortgage, Retirement, Brokerage, HSA, Crypto, Prepaid, Money Market, CD, Business, Property, Insurance, Gift Card | No types -- envelopes are generic categories shaped by name and purpose |
| Watchdog | No | Yes -- alerts when the balance drops below a limit |
| Allocation Plan | No | Yes -- envelopes can be flagged for inclusion |
| Web Address | Yes -- links to the institution's website | No |
| Opening Balance | Entered as an account transaction after creating the account | No |
| Balance Display | Always shown | Configurable per envelope |
| Grouping | Account groups (a special type) | Nested parent/child envelopes |
When to Use Each
Create an account for each place where you hold money:
- Your checking account
- Your savings account
- Each credit card
- Cash on hand
- Investment or retirement accounts
Create an envelope for each purpose you budget for:
- Fixed expenses: rent, utilities, insurance
- Variable expenses: groceries, dining, transportation
- Savings goals: emergency fund, vacation, new car
- Debt payments: credit card payoff, loan payments
How They Work Together
When income arrives as a deposit into your checking account, the account balance goes up. You then allocate that income across your envelopes using the Allocation Plan, which raises the envelope balances.
When you spend, the transaction reduces both the account balance (money left the bank) and the envelope balance (budget for that category was used). The money is gone from both views at the same time.
When you transfer between accounts (checking to savings), no envelope is affected -- the money still has the same purpose. When you transfer between envelopes (moving budget from dining to groceries), no account is affected -- the money still lives in the same bank.
Balance Equality
Principal Plan keeps the account view and envelope view in balance. Day-to-day deposits and spending usually change both views, while account transfers and envelope transfers move money within one view without changing the total. The balance of each view is always the same.
