Personal finance

Personal finance is the management of an individual's or household's financial resources, including income, spending, saving, investing, borrowing, insurance, taxation, and retirement planning. It involves making financial decisions over time to meet current obligations, manage risks, accumulate wealth, and achieve longer-term financial objectives.

Personal finance encompasses both day-to-day financial management and long-term financial planning. The appropriate financial strategy depends on an individual's income, expenses, assets, liabilities, financial goals, risk tolerance, and circumstances.

Components

The principal components of personal finance include:

income management;
budgeting;
saving;
investing;
debt management;
insurance;
taxation;
retirement planning;
estate planning;
risk management.

Income

Income represents money or other economic resources received by an individual or household.

Sources of income may include:

employment income;
self-employment income;
business income;
investment income;
rental income;
pension income;
government benefits;
other sources.

Understanding income and its stability is an important part of financial planning.

Budgeting

Budgeting is the process of planning and monitoring income and expenditure over a specified period.

A simplified budget relationship is:

$Net Cash Flow = Income - Expenses$

A positive net cash flow can provide resources for saving, investing, debt repayment, or other financial objectives.

Saving

Saving involves setting aside part of current income for future use.

Savings may be held in:

bank accounts;
cash equivalents;
fixed-income instruments;
other low-risk financial assets.

Savings can provide liquidity for short-term expenses and unexpected financial requirements.

Emergency fund

An emergency fund is a pool of readily accessible financial resources intended to cover unexpected expenses or temporary reductions in income.

Potential uses include:

medical expenses;
urgent repairs;
temporary unemployment;
unexpected household expenses.

The appropriate size of an emergency fund depends on an individual's income stability, expenses, liabilities, and other financial circumstances.

Investing

Investing involves allocating financial resources to assets with the expectation of generating future returns.

Common investment categories include:

equities;
bonds;
mutual funds;
exchange-traded funds;
real estate;
cash and cash equivalents;
other financial assets.

Investment decisions generally involve a trade-off between expected return, risk, liquidity, and investment horizon.

Asset allocation

Asset allocation refers to the distribution of investments among different asset classes.

An individual's asset allocation may consider:

financial objectives;
investment horizon;
risk tolerance;
liquidity requirements;
expected returns.

Diversification across asset classes can reduce concentration in a particular investment or market.

Diversification

Diversification involves spreading investments across different assets, sectors, geographic regions, or other categories to reduce concentration risk.

A diversified portfolio may contain multiple asset classes rather than relying on a single investment.

Diversification does not eliminate investment risk or guarantee a profit.

Portfolio management

Portfolio management involves selecting, monitoring, and adjusting investments to meet specified financial objectives.

Personal portfolio management may include:

asset allocation;
security selection;
diversification;
Portfolio rebalancing;
risk management;
performance evaluation.

Debt management

Debt management involves managing borrowing, repayment schedules, interest costs, and overall levels of indebtedness.

Common forms of household debt include:

mortgages;
personal loans;
student loans;
automobile loans;
credit-card balances.

A borrower may seek to reduce financing costs by prioritizing high-interest debt or refinancing when appropriate.

Debt-to-income ratio

The debt-to-income ratio compares recurring debt obligations with income.

A simplified representation is:

$Debt-to-Income Ratio = \frac{Monthly Debt Payments}{Gross Monthly Income} \times 100 %$

The ratio is commonly used by lenders when assessing a borrower's ability to service debt.

Credit

Credit refers to the ability to borrow funds or obtain goods and services with payment deferred to a future date.

An individual's access to credit and borrowing costs may be affected by factors such as:

credit history;
income;
existing debt;
repayment behavior;
credit utilization;
applicable lending criteria.

Insurance

Insurance is a risk-transfer mechanism through which an individual pays a premium in exchange for specified financial protection against covered risks.

Personal insurance may include:

health insurance;
life insurance;
disability insurance;
property insurance;
automobile insurance;
liability insurance.

Insurance can protect accumulated wealth and income against events that could otherwise cause significant financial losses.

Tax planning

Tax planning involves organizing financial affairs within applicable legal and regulatory requirements to understand and manage tax obligations.

Personal tax planning may consider:

income;
deductions;
investment income;
capital gains;
retirement contributions;
applicable tax incentives.

Tax rules vary among jurisdictions and can change over time.

Retirement planning

Retirement planning involves estimating future financial requirements and accumulating resources to support life after employment.

Potential retirement-income sources include:

pensions;
pension plans;
social-security benefits;
personal savings;
investment portfolios;
annuities;
rental or business income.

Retirement planning may consider inflation, investment returns, longevity, taxation, and expected expenditure.

Net worth

Net worth represents the difference between an individual's assets and liabilities.

It can be expressed as:

$Net Worth = Total Assets - Total Liabilities$

Assets may include financial investments, property, cash, and other valuable resources, while liabilities include outstanding debts and other financial obligations.

Net worth provides a measure of financial position at a particular point in time.

Cash flow

Personal financial management involves monitoring both income and expenditure over time.

A household may have substantial assets but experience financial difficulty if available cash is insufficient to meet immediate obligations.

Cash-flow management therefore considers:

income timing;
recurring expenses;
debt payments;
savings;
investment contributions;
unexpected expenses.

Financial goals

Personal financial goals may include:

building emergency savings;
purchasing a home;
financing education;
reducing debt;
accumulating investment assets;
funding retirement;
transferring wealth.

Financial goals can be categorized according to their expected time horizon.

Short-term and long-term planning

Short-term financial planning generally addresses needs occurring over a relatively short period, such as budgeting, emergency savings, and upcoming expenses.

Long-term planning may address:

retirement;
education funding;
wealth accumulation;
major asset purchases;
estate planning.

Different financial goals may require different levels of liquidity and investment risk.

Financial risk management

Personal financial risk management involves identifying and reducing risks that could materially affect an individual's financial position.

Potential risks include:

loss of employment income;
illness or disability;
unexpected expenses;
investment losses;
excessive debt;
inflation;
longevity.

Savings, insurance, diversification, and appropriate debt management can be used as components of a broader risk-management strategy.

Estate planning

Estate planning involves arranging the management and transfer of assets during and after an individual's lifetime.

It may include:

wills;
trusts;
beneficiary designations;
powers of attorney;
other legally recognized arrangements.

The applicable legal and tax consequences vary by jurisdiction.

Financial literacy

Financial literacy refers to the knowledge and skills required to understand and make informed financial decisions.

Important areas include:

budgeting;
interest rates;
inflation;
debt;
investing;
insurance;
taxation;
retirement planning.

Financial literacy can help individuals evaluate financial products and understand the consequences of financial decisions.
