Calculate how your savings grow over time with regular deposits and interest.
A savings calculator projects how your savings will grow over time with regular contributions and compound interest. Whether you are saving for an emergency fund, a home down payment, a car, or retirement, our compound interest savings calculator shows your exact savings trajectory to help you plan effectively.
Compound interest means you earn interest on both your principal and previously earned interest. A sum saved at 7% annual interest roughly doubles in about 10 years and nearly quadruples in 20 years — without adding any additional money. Adding regular monthly contributions accelerates growth dramatically through the power of compounding.
To calculate how much to save monthly to reach a goal: Monthly Savings = FV × r / ((1+r)^n − 1), where FV is future value goal, r is monthly interest rate, and n is months. For example, to save 500,000 (in your local currency) in 3 years at 6% annual interest, you need to save approximately 12,700 per month in that same currency.
Standard savings accounts at traditional banks typically offer modest interest rates, while high-yield savings accounts from online or smaller banks often offer meaningfully better rates in most countries. Money market funds and similar liquid investment options can offer better returns with easy access to your money. For amounts you won't need for a year or more, fixed deposits and bond funds typically offer better returns than a standard savings account. Always keep 3-6 months of essential expenses in easily accessible savings as an emergency fund, regardless of which country or currency you're saving in.
Set up automatic transfers on your salary credit date so money moves to savings before you can spend it. This "pay yourself first" approach is the most effective savings strategy. Even saving just 10% of your income consistently over 30 years builds substantial wealth through compounding. Start with any amount — consistency matters more than the initial amount saved.
Calculating how long it will take to reach a savings goal, or how much needs to be saved monthly to hit a target date, turns an abstract financial goal into a concrete, actionable number. This concrete framing tends to significantly improve follow-through compared to a vague intention to "save more," since a specific monthly target is easier to build into a budget and track progress against over time.
Interest earned on savings, even at modest rates offered by high-yield savings accounts, meaningfully accelerates progress toward a goal compared to saving the same amount in a zero-interest account, particularly for longer-term goals like a home down payment or emergency fund built up over several years. Choosing a savings vehicle with a competitive interest rate is a low-effort way to reach a savings goal somewhat faster without changing the monthly contribution amount at all.
Most financial advisors recommend building an emergency fund covering 3 to 6 months of essential expenses before aggressively pursuing other savings goals, since an emergency fund prevents unexpected expenses from derailing other financial progress by forcing high-interest debt or the liquidation of longer-term investments. Calculating this specific target amount, based on actual monthly essential expenses, is often the first savings calculation worth doing before setting other financial goals.
Setting up automatic transfers to a savings account on payday, before the money is available to spend elsewhere, tends to produce far more consistent results than manually deciding each month how much to save from whatever is left over. This "pay yourself first" approach removes willpower from the equation entirely, which is why it's one of the most commonly recommended tactics for reliably hitting a savings goal on schedule.
A common guideline is the 50/30/20 rule: save at least 20% of your monthly income. Increase this when possible to build a strong financial cushion.
Compound interest means you earn interest on your principal AND on previously earned interest. Over time, this creates exponential growth in your savings.

An emergency fund is 3-6 months of living expenses kept in an easily accessible account. It protects you from unexpected expenses without going into debt.
