50/30/20 rule
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 50/30/20 rule turns a budget into three broad buckets. Needs include housing, utilities, groceries, minimum debt payments, insurance, and other expenses that are difficult to pause. Wants include discretionary categories such as dining out, entertainment, travel, and nonessential shopping. The final bucket covers savings, investing, extra debt payoff, and other moves that improve future flexibility.
The framework is popular because it is easy to explain, not because it fits every household. High-rent cities, variable income, medical costs, or aggressive debt payoff can make the default split unrealistic. In those cases, the rule is still useful as a diagnostic: it shows which bucket is crowding out the rest of the plan.
Nethaven supports category budgets and transaction review so the ratio can be compared against actual spending instead of a one-time estimate.

Cash flow
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.
Sinking fund
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.
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.
