Calculators for everyday money
Project a balance, the portfolio that covers your spending, the return already earned, and the monthly amount that reaches a goal. Each page shows the formula beside the result.
Compound interestEnter a starting amount, a rate and what you add each month. The result separates deposits from interest.Financial independenceThe target is annual spending divided by the withdrawal rate. The time uses the same compound-interest calculation as the other page.Investment returnEnter the starting balance, the ending balance and the number of months. The annual rate is the effective rate that compounds to the same result.Monthly contribution to a goalEnter the goal, what you already have, the rate and the term. Each contribution lands at the end of the month.Loan payment calculatorThe fixed payment is the standard installment loan. Declining payments keep principal repayment constant, so the installment falls as the balance falls.Percentage calculatorPick the kind of calculation. Fifteen percent of 200 is 30. From 80 to 100 is a 25% increase.
