How to use Use the APY published for the account and a monthly deposit you realistically expect to maintain.
Enter current savingsAdd the amount already available in the savings account. Enter zero when starting without an opening balance.
Add monthly depositsEnter the amount you expect to add at the end of each month throughout the projection.
Enter the APYUse the annual percentage yield published for the account. Enter 4 for an APY of 4.00%.
Choose the periodSelect the number of months or years you plan to keep saving under the entered assumptions.
Use the resultReview the future balance, deposits, interest, growth graph, and specialist savings report.
What your result means The result separates what you put into the account from what the assumed yield adds over time.
Future balanceProjected account valueThe opening balance, monthly deposits, and estimated compound interest combined.
DepositedYour own moneyThe opening savings plus every scheduled monthly deposit included in the period.
InterestEstimated account growthThe difference between the projected future balance and the total amount deposited.
Interest shareCompounding contributionThe percentage of the projected final balance created by interest rather than deposits.
Current situationStart with actual valuesUse the balance shown on the most recent account statement.
Future situationTreat the result as a projectionThe estimate assumes the entered yield and deposit remain unchanged.
Useful reviewRecalculate after changesUpdate the plan when the APY, income, or regular deposit changes.
practical useSave the dated reportUse the report to document assumptions, milestones, yearly values, and limitations.
Formula APY is converted to an effective monthly rate so a separate compounding-frequency input is unnecessary.
Monthly rate
r = (1 + APY)1/12 − 1
Future savings
FV = P(1 + r)n + C × ((1 + r)n − 1) ÷ r
Total deposited
D = P + (C × n)
Interest earned
I = FV − D
Symbols and assumptions:
P is current savings, C is the end-of-month deposit, APY is entered as an annual percentage, r is the effective monthly rate, and n is the number of months. When APY is zero, future savings equal current savings plus all deposits. Taxes, fees, withdrawals, changing rates, account tiers, and minimum-balance rules are excluded.
Tips and common mistakes Keep the projection realistic and update it when the real account or saving habit changes.

Practical savings tips

  • Automate the monthly transfer shortly after payday.
  • Use a sustainable deposit that can be maintained consistently.
  • Review the account yield whenever the bank changes its rate.
  • Check fees, balance requirements, and promotional-rate conditions.
  • Recalculate after material income or expense changes.
  • Compare the projection with actual statements periodically.
  • Avoid assuming an unusually high APY will remain available for many years.

Common mistakes

  • Entering 0.04 instead of 4 for a 4% APY.
  • Confusing APY with a monthly interest rate.
  • Counting the opening balance twice.
  • Ignoring fees or minimum-balance conditions.
  • Assuming the rate will never change.
  • Including planned withdrawals in a deposit-only calculation.
  • Treating a projection as a guaranteed account balance.
Frequently asked questions Answers about compound interest, deposit timing, APY, currencies, inflation, and result limitations.
It estimates the future value of current savings and regular monthly deposits using a constant annual percentage yield.
Yes. Interest is calculated on the deposited principal and previously accumulated interest.
The selected timing is end of each month. Switch the deposit-timing control to compare beginning-of-month deposits.
Actual results can differ because of changing rates, deposit dates, skipped deposits, withdrawals, fees, taxes, account tiers, and the bank’s interest-crediting method.
No. It reports the projected account balance in nominal currency. Inflation-adjusted purchasing power belongs in a separate inflation calculation.
Yes. The currency selector changes symbols and number formatting only. It does not change the mathematics or convert exchange rates.
Yes. With a zero APY, the result is the opening balance plus all scheduled monthly deposits.
No. It is an educational planning estimate based on the values and assumptions entered.

How deposits and compound interest build the projected account balance across the selected period.

End of year 1—Projected balance after 12 months

Final year growth—Balance added during the final 12 months
Interest contribution—Share of final balance from interest
MilestoneThe first meaningful savings milestone will appear here.
Final-year movementThe amount added during the final year will appear here.
Main growth driverThe report will identify whether deposits or interest remain the main driver.
Reading the chart: Teal represents money deposited. Coral represents interest earned above deposited money. The dark line shows the projected total balance.
Higher depositRaises the path directlyEvery additional deposit increases principal available to earn interest.
Higher APYWidens the interest layerA higher yield increases growth but may not remain available.
More timeExtends compoundingLonger periods allow accumulated interest to earn interest.

Method and guidance

Calculation Guide

Formula, assumptions, practical tips, common mistakes, FAQs, references, and important limitations.

Formula

r = (1 + APY)1/12 − 1
FV = P(1 + r)n + C × ((1 + r)n − 1) ÷ r
Deposited = P + Cn · Interest = FV − Deposited

The worked example will appear after calculation.

Assumptions

  • APY remains constant.
  • Deposits occur at month end.
  • Monthly deposit remains unchanged.
  • Interest remains in the account.
  • No withdrawals are made.
  • Taxes, fees, tiers, and minimum-balance rules are excluded.
  • Displayed values are rounded.

Practical tips

  • Automate deposits after payday.
  • Use a sustainable monthly amount.
  • Recalculate when APY changes.
  • Check account fees and conditions.
  • Compare projections with actual statements.
  • Avoid assuming promotional yields will continue indefinitely.

Common mistakes

  • Entering 0.04 instead of 4 for 4%.
  • Confusing APY with a monthly rate.
  • Counting the opening balance twice.
  • Ignoring fees and account tiers.
  • Including withdrawals in a deposit-only calculation.
  • Treating the projection as guaranteed.
