Compound interest is often called the "eighth wonder of the world." Unlike simple interest, which is earned only on your original principal, compound interest earns returns on your returns. Our free compound interest calculator lets you model this growth with daily, monthly, quarterly, or annual compounding frequencies and optional recurring contributions.
A saving calculator helps you understand exactly how much to set aside each month to hit a savings target on time. Whether you're saving for a home down payment, emergency fund, or retirement, knowing your required monthly deposit — adjusted for realistic interest earnings — removes the guesswork from your budget spreadsheet.
Your net worth is the single most important number in personal finance. It's the difference between everything you own (assets) and everything you owe (liabilities). Use our free net worth calculator to add your checking accounts, investments, real estate, vehicles, mortgage, car loans, credit cards, and student debt to get a complete picture.
Knowing your nominal return isn't enough. Our investment return calculator computes your CAGR (compound annual growth rate), total return percentage, net profit in dollars, and inflation-adjusted real return. It also applies the Rule of 72 to estimate how long it takes your investment to double at your given rate of return.
A stock profit calculator accounts for the details that raw price appreciation ignores: brokerage commissions, capital gains taxes, and total cost basis. Enter your shares, buy price, sell price, fees, and tax rate to instantly see your gross profit, net profit, ROI, and after-tax return.
The dividend reinvestment calculator (DRIP calculator) demonstrates why long-term dividend investors often significantly outperform those who take dividends as cash. By reinvesting dividends to buy more shares, each subsequent quarter's dividend is larger — creating an exponential compounding effect. Model any dividend yield, dividend growth rate, stock price appreciation, and time horizon to see exactly how much additional wealth DRIP creates versus a simple buy-and-hold strategy.
