Compare accounts →Want to know what your savings will be worth in 5, 10 or 30 years? This savings calculator combines your starting balance, monthly deposits and interest rate to project your future balance and show exactly how much of it comes from your own deposits versus earned interest. It's perfect for planning toward a goal — an emergency fund, a house deposit, a wedding or a holiday. Adjust the monthly contribution and watch how small, consistent deposits compound into a meaningful sum over time.

What is Savings?
Saving is the practice of setting money aside regularly rather than spending it, ideally in an account that pays interest so your balance grows even faster. A savings calculator projects that growth by combining three inputs: how much you start with, how much you add over time, and the rate at which your balance earns interest.
The most powerful habit in saving is consistency. Automatic monthly transfers — sometimes called "paying yourself first" — remove the temptation to spend and turn saving into a background process. Even modest amounts add up: $200 a month is $2,400 a year, and with interest compounding on top, the total after a decade is considerably more than the sum of your deposits.
Where you keep your savings matters. A traditional checking account often pays little or no interest, while a high-yield savings account, money market account or term deposit (CD) can pay meaningfully more. In recent years, high-yield online accounts have offered rates many times higher than the national average, so shopping around can add hundreds of dollars a year at no extra effort. Always check whether an advertised rate is introductory and what the ongoing rate will be.
It helps to separate your savings by purpose. An emergency fund — typically three to six months of essential expenses — should sit in a safe, instantly accessible account. Money for goals more than five years away might be better invested for higher growth, accepting more short-term volatility. Short-term goals belong in safe, liquid savings where the balance won't fluctuate.
Inflation is the quiet enemy of savings: if your account pays less than the inflation rate, your money loses purchasing power over time even as the nominal balance rises. That's why, for long horizons, many people blend savings with investments. Use this calculator to set a realistic monthly target and watch how your future balance responds as you adjust the inputs.
The formula
FV = P(1 + r/n)^(nt) + PMT · [ ((1 + r/n)^(nt) − 1) / (r/n) ] where: FV = future value of savings P = initial deposit PMT = regular contribution per period r = annual interest rate (decimal) n = compounding periods per year t = number of years
Frequently Asked Questions
How much should I save each month?+
A widely used guideline is to save at least 20% of your take-home pay, split between an emergency fund, retirement and other goals. The right number depends on your income and goals — use this calculator to see what a given monthly amount grows into.
What is a high-yield savings account?+
A high-yield savings account pays a much higher interest rate than a standard account, often offered by online banks with lower overhead. The balance is typically liquid and FDIC- or equivalently insured, making it ideal for emergency funds and short-term goals.
Is saving better than investing?+
They serve different roles. Saving is for safety and short-term goals — the balance won't drop. Investing aims for higher long-term growth but carries short-term risk. Most people do both: an emergency fund in savings and longer-term money invested.
How does compound interest help my savings?+
Compound interest means you earn interest on your interest, not just your deposits. The longer your money stays in the account and the more frequently it compounds, the larger the share of your final balance that comes from interest rather than your own contributions.
