Savings Calculator
Project savings growth with monthly deposits and interest.
A savings calculator, or monthly savings growth estimator, projects how a starting balance plus regular monthly deposits will grow over time at a given interest rate - the same math behind a bank savings account, a fixed monthly deposit plan, or a Recurring Deposit (RD) in countries where that product is common. This savings goal calculator can also work backward - showing how much you'd need to deposit each month to reach a specific target amount by a certain date, or what your total yearly savings will add up to along the way.
Enter your starting balance, planned monthly deposit, interest rate, and time horizon to see your projected savings balance, or solve for the monthly deposit needed to hit a specific goal.
Worked Calculation Examples
| Scenario | Result | Calculation Step |
|---|---|---|
| $2,000 starting balance, $300/month, 4% APY, 3 years | ≈$13,710 | Monthly rate = 0.04/12 ≈ 0.003333 over 36 months. Growth of starting balance ≈ $2,000 × 1.12727 ≈ $2,254.54. Growth of deposits ≈ $300 × [(1.12727 − 1) ÷ 0.003333] ≈ $11,455.20. Total ≈ $13,709.74. |
| Reverse goal: $10,000 in 2 years at 3% APY, starting from $0 | ≈$404.86/month needed | Solving the annuity formula for the monthly deposit at a monthly rate of 0.0025 over 24 months gives PMT = $10,000 × 0.0025 ÷ (1.0025^24 − 1) ≈ $404.86/month. |
How Bank Savings Interest Compares to Investing
Traditional savings accounts and high-yield savings accounts pay interest that compounds, usually daily or monthly, but at rates that are typically much lower than long-term stock market averages - savings account rates have historically ranged from under 1% to several percent depending on the interest rate environment, versus a historical stock market average closer to 10% before inflation. The trade-off is safety and liquidity: savings account balances aren't subject to market swings and are typically FDIC-insured up to $250,000 per depositor, per bank, which makes them appropriate for money you can't afford to risk losing, like an emergency fund or a near-term goal.
Reverse-Engineering a Savings Goal
Instead of starting with a monthly deposit and seeing what it grows to, this calculator can also solve the reverse problem: given a target amount and a deadline, how much do you need to save each month? This is useful for concrete goals with a fixed date - a wedding, a down payment, a vacation - where the total contribution needed depends on how much time you have and what interest rate you are earning along the way.
Why Consistency Beats Timing for Savings Goals
Because savings goals are typically short-to-medium term (months to a few years) rather than decades-long investment horizons, the exact interest rate earned usually matters less than simply depositing consistently. An automatic monthly transfer set up the day you get paid removes the temptation to skip a month, and even a modest, unglamorous savings account rate compounds steadily toward a fixed-date goal without the volatility risk that a market-based investment would introduce for money you need on a specific date.

Frequently Asked Questions
How much do I need to save per month to reach $10,000?
It depends on your timeline and interest rate - for example, saving toward $10,000 in 2 years with a modest interest rate typically requires depositing somewhere in the $390-$410 range per month; enter your own numbers into the calculator for an exact figure.
What interest rate should I use for a savings account?
Use your actual bank's current advertised rate for a savings or high-yield savings account, since these can vary significantly - checking your bank's current rate will give a far more accurate projection than a generic assumption.
Is a savings account better than investing for short-term goals?
Generally yes, for goals under 3-5 years. Savings accounts don't carry market risk, so your balance won't drop right before you need the money, which matters more for near-term goals than the lower return rate.
How often does savings account interest compound?
Most banks compound savings account interest daily and credit it to your account monthly, which produces a slightly higher effective return than annual compounding at the same stated rate.
Is my savings account insured?
In the U.S., savings accounts at FDIC-member banks are insured up to $250,000 per depositor, per bank, per ownership category - a strong safety net for money not exposed to market risk.
Should I automate my monthly savings deposits?
Many people find automatic transfers set up right after payday more reliable than manually saving what is left over, since it removes the temptation to spend the money before it is set aside.
