Note: Additional contributions applied at the end of each period, following interest calculation. This calculator is for illustrative purposes only and does not constitute financial advice.

Estimate how your savings balance could grow with compound interest plus optional deposits and withdrawals. Choose how interest is quoted and compounded, model contribution schedules, and review future value, APY, and time-weighted return.

How to use our savings calculator

  1. Choose a currency and enter your initial savings balance.
  2. Set the interest rate and whether it is quoted daily, weekly, monthly, quarterly, or yearly — then pick how often interest compounds.
  3. Enter the duration in years and months.
  4. Optional: model regular deposits, withdrawals, or both with full frequency options (daily through yearly).
  5. Toggle inflation adjustment if you want contributions to grow each year at your inflation rate.
  6. Click Calculate for future value, interest earned, APY, breakdown table, and chart.

For investment-style modeling with annual rates and advanced withdrawal modes, switch to the Regular Investment Calculator using the tabs above the form.

How savings growth is calculated

This calculator applies compound interest each compounding period on your current balance, then adds deposits or subtracts withdrawals at the end of each period (after interest). That matches common savings-plan conventions and the reference behavior for illustrative projections.

The effective annual rate (APY) in results shows what your quoted period rate becomes when compounding is included. A high monthly nominal rate compounded monthly produces a much higher APY — always compare products using the same quoting convention.

Deposits and withdrawals

Deposits and withdrawals can run on different schedules — for example, $100 deposited monthly with $50 withdrawn quarterly. The breakdown table shows both flows per period and a running total of net contributions plus your opening balance.

Examples and use cases

Worked example

$5,000 opening balance at 4.5% yearly (compounded monthly) for 3 years with $100 deposited at the end of each month:

  • Periodic rate ≈ 0.375% per month
  • Future value ≈ $9,250 (including all deposits)
  • Total interest earned ≈ $3,550 on roughly $8,600 principal invested

Real-world use cases

  • Emergency fund planner: A freelancer models $200 bi-weekly deposits into a 4% APY account to see when they reach a six-month expense cushion.
  • College savings: Parents combine a $2,000 opening gift with $50 monthly contributions to compare monthly vs quarterly compounding on a long-term savings goal.
  • Retirement catch-up: Someone nearing retirement toggles inflation adjustment to see how rising contribution amounts affect nominal balance over 10 years.

Common questions

Quick answers before you start calculating.

The rate period is how your quoted rate is expressed (e.g. 5% per month). Compounding frequency is how often that interest is added to the balance. They can differ — a yearly rate compounded monthly uses a different per-period rate than a monthly rate compounded monthly.
