Salary
Gross Salary
Gross salary is the total amount of money an employee earns before any deductions are taken out, including taxes, Social Security, Medicare, retirement contributions, health insurance premiums, and other withholdings. It is typically expressed as an annual figure in employment contracts and is the starting point for calculating take-home pay.
Example
If your employment contract states an annual salary of $75,000, that is your gross salary. After federal income tax ($9,000), state income tax ($3,000), Social Security ($4,650), Medicare ($1,088), and health insurance ($2,400), your net take-home pay would be approximately $54,862 per year.
Net Salary
Net salary, also known as take-home pay, is the amount of money an employee receives after all deductions have been subtracted from gross salary. These deductions include federal and state income taxes, Social Security contributions, Medicare taxes, retirement plan contributions, health insurance premiums, and other voluntary deductions.
Example
An employee with a gross salary of $75,000 might have a net salary of $54,862 after federal and state taxes ($12,000), Social Security ($4,650), Medicare ($1,088), 401(k) contributions ($3,000), and health insurance ($2,400). Use a salary calculator to estimate your specific net salary.
Tax
Effective Tax Rate
The effective tax rate is the average percentage of total income paid in taxes. Unlike the marginal tax rate, which applies only to the last dollar earned, the effective tax rate provides a comprehensive view of your total tax burden by dividing total tax paid by total income. It is always lower than the marginal tax rate in a progressive tax system.
Example
If you earn $75,000 and pay $12,000 in total income taxes, your effective tax rate is 16% ($12,000 / $75,000). Despite being in the 22% marginal tax bracket, your effective rate is lower because portions of your income are taxed at lower brackets (10% and 12%).
Marginal Tax Rate
The marginal tax rate is the tax rate applied to the last dollar of income earned. In a progressive tax system, income is taxed in brackets at increasing rates. Your marginal tax rate is the rate of the highest bracket your income reaches, and it only applies to the portion of income within that bracket, not your entire income.
Example
For 2025-2026, a single filer earning $75,000 falls into the 22% marginal tax bracket. However, only income above $47,150 is taxed at 22%. The first $11,600 is taxed at 10%, and income from $11,601 to $47,150 is taxed at 12%. The overall effective tax rate is lower than 22%.
Mortgage
APR (Annual Percentage Rate)
APR represents the total annual cost of borrowing money, including the interest rate plus any fees or additional costs associated with the loan. It is expressed as a percentage and provides a more complete picture of loan costs than the nominal interest rate alone. APR is standardized, making it easier to compare loan offers from different lenders.
Example
A mortgage with a 6.0% interest rate and $3,000 in origination fees might have an APR of 6.3%. The APR is higher than the interest rate because it spreads the fees across the loan term. When comparing mortgage offers, the lower APR typically represents the better deal, assuming all other terms are equal.
Debt-to-Income (DTI) Ratio
The debt-to-income (DTI) ratio is the percentage of your gross monthly income that goes toward debt payments, including mortgages, credit cards, student loans, auto loans, and other debts. Lenders use DTI to assess your ability to manage monthly payments and repay borrowed money. A lower DTI indicates better financial health.
Example
If your gross monthly income is $6,000 and your total monthly debt payments are $2,100 (mortgage: $1,500, car loan: $400, credit cards: $200), your DTI ratio is 35%. Most lenders prefer DTI ratios below 43% for mortgage approval, and below 36% for optimal rates.
Mortgage Affordability
Mortgage affordability refers to how much home you can reasonably purchase based on your income, existing debts, down payment, and current interest rates. Lenders use the 28/36 rule: no more than 28% of gross monthly income for housing costs and no more than 36% for total debt payments. Your credit score and employment history also affect affordability.
Example
With a $75,000 annual salary ($6,250/month), no other debts, and a 20% down payment, you can afford approximately $2,500 monthly housing costs. At current interest rates, this translates to a home price of roughly $350,000-$400,000 depending on property taxes and insurance.
Investment
APY (Annual Percentage Yield)
APY measures the total amount of interest earned on a deposit account over one year, taking into account the effect of compound interest. Unlike simple interest rates, APY reflects how often interest compounds (daily, monthly, quarterly), making it the most accurate measure of an account's earning potential. Higher compounding frequency results in higher APY.
Example
A savings account offering 4.50% interest compounded monthly has an APY of 4.59%. This means $10,000 deposited would grow to $10,459 after one year. The same 4.50% rate compounded daily would yield an APY of 4.60%. Always compare APYs rather than interest rates when evaluating savings accounts.
Compound Interest
Compound interest is interest calculated on both the initial principal and the accumulated interest from previous periods. Unlike simple interest, which is calculated only on the principal, compounding allows your money to grow exponentially over time. The frequency of compounding (daily, monthly, annually) affects the total growth.
Example
If you invest $10,000 at 7% annual return compounded yearly, after 30 years you would have approximately $76,123 without adding any additional money. With monthly contributions of $500, the same investment would grow to approximately $611,729. This exponential growth is why starting to invest early is so powerful.
General
Inflation
Inflation is the rate at which the general level of prices for goods and services rises over time, eroding purchasing power. It is typically measured by the Consumer Price Index (CPI), which tracks the cost of a basket of common goods and services. Central banks target moderate inflation (typically 2%) as a sign of a healthy economy.
Example
If the inflation rate is 3% per year, an item that costs $100 today will cost approximately $103 in one year. Over 10 years at 3% inflation, that same item would cost about $134. This means your savings need to grow at least at the inflation rate to maintain purchasing power.
