Savings Calculators

Saving differs from investing mainly in certainty: savings accounts and deposits pay a stated rate, so the mathematics here produces firmer answers than any market projection. The Savings Calculator models an account balance growing with regular deposits and compound interest, and can tell you when you'll reach a target. The Monthly Investment Calculator inverts the question — enter the goal and the timeframe, and it solves for the monthly amount required. The Simple Interest Calculator covers the cases where interest doesn't compound: some fixed deposits, short-term lending and many bond coupons.

Which one fits your question?

• "I can save X per month. Where will I be in N years?" Start with the Savings Calculator. Enter your balance, deposit and the account's APY; set a goal amount if you have one and it will mark the month you cross it.
• "I need X by a certain date. How much must I put away?" That inverse problem belongs to the Monthly Investment Calculator, which also shows how sharply the required amount falls when you add time.
• "My deposit pays interest that doesn't reinvest." Use the Simple Interest Calculator, which also quantifies what reinvesting the same rate would add.
• "Should this money be saved or invested at all?" For horizons under a few years, or money you cannot afford to see dip, a stated savings rate usually wins the decision; the guide on inflation and savings covers the trade-off, and the investment calculators handle the market side.
