Envelope Budgeting Glossary

Plain-English definitions for the budgeting and personal-finance terms you'll see across this site.

A

Allocation

An automated rule that distributes a single deposit (e.g. a paycheck) across multiple envelopes based on percentages or fixed dollar amounts. Think of it as a pre-arranged delivery system: when income arrives, the allocation routes it where it's already been assigned.

See also: Envelope Method Guide · Monthly Budget below.
Amortization

The process of paying off a loan through regular payments over time. Early payments are mostly interest; later payments are mostly principal. A standard amortization schedule shows exactly how each payment is split for the life of the loan. LazeeFish's Debt Tracker calculates this split automatically from each imported payment.

Auto-Categorization

The process of automatically tagging and posting incoming bank transactions to the correct envelope based on rules you've defined (e.g. "any transaction matching STARBUCKS goes to the Coffee envelope as an Expense"). Eliminates the manual review step for recurring merchants.

See also: Auto-Categorization feature.
Auto-Split (debt)

A feature that automatically splits a loan payment into its principal and interest components based on the current outstanding balance and APR, without requiring manual calculation. When a mortgage, auto loan, or credit card payment arrives via bank sync, LazeeFish applies the amortization formula and posts the correct amounts to each portion of the debt envelope.

See also: Amortization above · Debt Tracker.
Avalanche Method (debt)

A debt payoff strategy where extra payments go toward the highest-APR debt first, while paying minimums on all others. Mathematically minimizes total interest paid over the life of your debts. Compare with the Snowball Method, which prioritizes smallest balance instead.

B

Bank Connection

The link between your bank account and LazeeFish, established through Plaid. A connection holds a read-only access token that lets us pull your transactions; it does not store your bank login credentials. Each connection displays its last sync date, transaction count, and any error message — visible in Settings → Bank Connections.

See also: Bank Sync feature.
Bill Reminder

A template in LazeeFish that tracks a recurring payment — its name, expected amount, cadence, and due date. Each scheduled occurrence appears as Expected until Plaid imports a matching transaction (at which point it becomes Fulfilled) or the user marks it Skipped. See also: Recurring Bills feature.

Budget

A plan for what to do with your money before you spend it. The envelope method treats the budget as the source of truth — it tells your money where to go rather than recording where it went.

C

Cash Stuffing

The TikTok-era nickname for the envelope method — physically dividing cash into labeled envelopes for each spending category. Mechanically identical to the original system, just more visual.

See also: The Brain Science Behind Cash Stuffing.
Clearing Account

The temporary holding envelope a deposit lands in before being divided across other envelopes by an allocation. For most people this is the "Income" envelope: paychecks land there, then get split into Rent, Groceries, Savings, and so on.

D

Debt Envelope

In envelope budgeting, a debt envelope holds a negative balance equal to the current outstanding principal. As payments are applied (split into principal and interest via Auto-Split), the principal portion reduces the negative balance, moving it toward zero. When the balance reaches zero, the debt is paid off and the envelope can be closed or repurposed.

E

Entity

The other party in a transaction — the merchant (Whole Foods), employer (Acme Corp), or person (Mom). LazeeFish keeps your entity list under your control so you can group, rename, or merge them as needed.

Envelope

A category of spending or saving with a running balance. The core unit of the envelope method. Examples: Groceries, Rent, Vacation Fund, Emergency Fund. When the balance hits zero, you stop spending in that category until next month.

See also: Envelope Method Guide.
Envelope Method

A budgeting system that assigns every dollar of income to a specific category before the month begins, and only allows spending from a category if it still has a balance. The system makes constraints concrete instead of abstract — you can't accidentally overspend if there's nothing left to spend.

F

Fixed Expense

A recurring expense whose amount doesn't change month to month — rent, mortgage, subscription bills. These get their own envelopes and are funded first; what's left covers variable categories.

M

Mapping Rule

The configuration that tells the auto-categorization engine how to route a transaction. A rule looks like "if the merchant name contains NETFLIX, post it to the Streaming envelope as Subscriptions, with the tag recurring."

See also: Auto-Categorization above.
Monthly Budget

A specific allocation in LazeeFish that runs once at the start of every month, distributing income from the clearing account into your envelopes according to amounts you've set. It only fires once per month — running it again on the same month is a no-op.

P

Pain of Paying

A behavioral-economics concept describing the psychological friction of spending money. Paying in cash produces high pain (you literally watch the bills leave); paying with a credit card produces low pain (it feels free until the statement). Higher pain = lower spending. The envelope method increases pain on purpose.

See also: The science article.
Pending Transaction

A transaction LazeeFish has imported from your bank but hasn't yet posted to a specific envelope. Pending transactions wait in the Pending Transactions list for you to assign them — or, if a mapping rule matches, they're auto-posted instead.

Plaid

The third-party service that connects financial apps to banks. Used by Venmo, Robinhood, Chime, and thousands of others. LazeeFish uses Plaid for read-only bank sync so your bank credentials never reach our servers.

See also: Bank Sync feature.
Posted Transaction

A transaction that's been assigned to an envelope and committed to the ledger. Posted transactions affect your balances; pending ones don't.

R

Reconciliation

The act of comparing your envelope balances to the actual balances in your bank accounts to verify they match. With automatic bank sync, this is mostly handled for you — just a periodic check.

Recurring Transaction

A transaction that happens on a predictable schedule — rent, subscriptions, utility bills, loan payments. LazeeFish can scan 8 months of Plaid history to detect recurring patterns and suggest bill templates from them. Once a template exists, each occurrence is tracked and auto-fulfilled when the matching import arrives.

S

Savings Goal

An envelope with a target amount, an optional deadline, and a reset cadence (one-time, monthly, quarterly, or annually). The dashboard shows progress toward the target and flags goals as Met or Overdue. The consumer-friendly term for a sinking fund.

See also: Savings Goals App, Sinking Funds: How to Stop Being Surprised.
Sinking Fund

An envelope you add money to over time for a known future expense — annual insurance premiums, a vacation, holiday gifts, a new laptop in three years. Distinct from an emergency fund, which is for unknown expenses. In LazeeFish, sinking funds are implemented as savings goals: an envelope plus a target and (optionally) a deadline.

See also: Sinking Funds: How to Stop Being Surprised.
Skip if Goal Met

A monthly-budget option that, once a savings goal hits its target, redirects that envelope's allocation back to the clearing envelope instead of overflowing the goal. Useful for one-time goals where you don't want to keep funding past 100%.

Snowball Method (debt)

A debt payoff strategy where you pay minimums on all debts and put any extra money toward the smallest balance first. Once that debt is eliminated, you roll its payment into the next-smallest, creating accelerating momentum. Creates psychological wins as debts are eliminated one by one. Compare with the Avalanche Method, which targets the highest APR first to minimize total interest.

Subscription Tracker

A LazeeFish feature that automatically detects recurring subscription charges from your connected bank history — Netflix, Spotify, gym memberships, and anything that repeats on a regular schedule. Detected patterns appear as suggestions; you can accept them as recurring bill templates (with expected dates and amounts) or dismiss them. Unlike standalone subscription trackers such as Rocket Money, the LazeeFish subscription tracker is free and integrated with the rest of your envelope budget.

See also: Subscription Tracker feature, Recurring Bills.

T

Tag

A free-form label you can attach to a transaction in addition to its envelope. Useful for cross-cutting analysis: tag a Whole Foods purchase with both groceries and tax-deductible, then filter by either.

See also: Tags & Categories feature.
Transaction Type

The classification of a transaction's kind: Income, Expense, Transfer, Refund, etc. Distinct from the envelope (the where) and the entity (the who).

Transfer

Moving money from one envelope to another. Recorded as a paired transaction (negative on the source, positive on the destination) so the total ledger always nets to zero.

Z

Zero-Based Budget

A budgeting approach where every dollar of income is assigned to a category until the un-allocated balance reaches zero. The envelope method is one form of zero-based budgeting — every dollar lands in some envelope, leaving none floating around unaccounted for.
