Personal finance terms, explained clearly

The 50/30/20 rule is a budgeting framework that splits take-home income into needs, wants, and savings or debt payoff. A common version assigns 50% to needs, 30% to wants, and 20% to savings, but the ratios are best treated as a starting point.

The avalanche method is a debt payoff strategy where you pay extra toward the highest interest rate first while making minimum payments on every other debt. It usually minimizes total interest, but progress can feel slower if the highest-rate balance is large.

Brokerage sync connects an investment account so holdings and balances can update automatically in a finance app. Instead of entering every ETF, stock, or retirement balance by hand, sync brings account values into the portfolio and net worth view.

Cash flow is the movement of money into and out of your accounts over a period of time. Positive cash flow means income exceeded spending; negative cash flow means spending, debt payments, transfers, or investments exceeded incoming money.

An expense ratio is the annual cost of owning a mutual fund or ETF, shown as a percentage of invested assets. A 0.20% expense ratio costs about two dollars per year for every thousand dollars invested, before market gains or losses.

Liquid assets are assets you can turn into usable cash quickly without a major price discount. Checking balances, savings, money market funds, and some brokerage holdings are liquid; homes, vehicles, collectibles, and locked retirement funds are less liquid even if they add to net worth.

Net worth is the value of everything you own minus everything you owe. It combines cash, investments, property, vehicles, and other assets, then subtracts credit cards, loans, mortgages, and other liabilities so you can see the broad direction of your financial position.

A sinking fund is money set aside gradually for a known future expense. Instead of treating car insurance, holiday travel, annual subscriptions, or home repairs as surprises, you save a smaller amount each month before the bill arrives.

The snowball method is a debt payoff strategy where you pay extra toward the smallest balance first while making minimum payments on the rest. When that debt is gone, its payment rolls into the next smallest balance, creating visible wins and momentum.

Transaction categorization assigns each transaction to a spending or income category such as groceries, rent, utilities, dining, subscriptions, or transfers. Accurate categories make budgets useful because they turn raw account activity into patterns you can review and act on.
