The savings calculator projects a starting balance with regular deposits and interest compounded at the deposit frequency. It is designed for simple savings goals such as building an emergency fund or planning a future purchase.
How to use this calculator
Enter your current balance, recurring deposit, deposit frequency, expected annual rate, and time horizon. Deposits are assumed to occur at the end of each period and earn interest in subsequent periods.
Formula & calculation method
Future value = starting balance growth + accumulated future value of depositsThe periodic rate is the annual nominal rate divided by deposits per year. Both the starting balance and each deposit grow at that periodic rate. Total deposits include the starting balance plus all recurring deposits; interest is the final balance minus total deposits.
Worked example
Starting with 1,000 and adding 200 monthly for five years gives a clear view of how much came from your deposits and how much came from the assumed 4% return. Changing the horizon often has a noticeable compounding effect.
Why this is useful
The calculator turns a savings goal into concrete deposit and growth figures. It also helps test whether a higher deposit, a longer period, or a different assumed rate has the greatest effect on your plan.
Limitations to keep in mind
Actual account rates may change and may compound on a different schedule. The projection excludes taxes, fees, inflation, and irregular deposits. It is a planning estimate rather than a promise of account performance.
Frequently asked questions
Is the starting balance included in total deposits?
Yes. Total deposits combine the initial balance and every recurring deposit, allowing interest to be calculated separately.
What if I do not plan to add money?
Set the regular deposit to zero. The calculator will project only the starting balance and its assumed interest.
Does it account for inflation?
No. The result is in nominal future currency units, not inflation-adjusted purchasing power.
