## How long will it take to reach my savings goal?

Reaching a savings goal depends on the amount you start with, how much you add each period and the interest rate you earn.

## Formula

Each period, the current balance earns rate ÷ compounding periods, then the recurring contribution is added at the end of that period.

- Each period, the current balance earns rate ÷ compounding periods, then the recurring contribution is added at the end of that period.
- Inputs used: Starting balance, Recurring deposit, Contribution frequency, Annual interest rate, Duration, Compound frequency.
- Edge handling: Starting balance is required.; Starting balance cannot be negative.; Starting balance must be no more than 1000000000000.; Recurring deposit is required.; Recurring deposit cannot be negative..

## Inputs

- Starting balance
- Recurring deposit
- Contribution frequency
- Annual interest rate
- Duration
- Compound frequency

## Worked example: Ten-year growth estimate

Start with $10,000 and add $200 monthly at an estimated 5% annual rate.
1. Start with Starting balance: 10000, Recurring deposit: 200, Contribution frequency: 12, Annual interest rate: 5, Duration: 10, Compound frequency: 12.
2. Apply the method: Each period, the current balance earns rate ÷ compounding periods, then the recurring contribution is added at the end of that period.
3. Start with $10,000 and add $200 monthly at an estimated 5% annual rate.

## Common questions

### How long will it take to reach my savings goal?

Reaching a savings goal depends on the amount you start with, how much you add each period and the interest rate you earn. Check the formula, example, and limitations on this page before using the result for a real finance decision.

### When are contributions added?

They are modeled at the end of each contribution period. Check the formula, example, and limitations on this page before using the result for a real finance decision.

### Is the rate guaranteed?

No. The entered constant rate is only an estimate.

### How do I use the Savings Calculator?

Enter the required values for Starting balance, Recurring deposit, Contribution frequency, Annual interest rate, Duration, and the other fields shown. The calculator applies the formula on this page and shows the main result with any supporting breakdown so you can check the arithmetic.

### What formula does the Savings Calculator use?

Each period, the current balance earns rate ÷ compounding periods, then the recurring contribution is added at the end of that period. The visible formula section above lists the calculation path and the edge cases the page handles, so the result can be checked without relying on the form alone.

### Can the Savings Calculator be used for exact decisions?

Use it as a calculation aid, not as a substitute for checking the underlying rule, contract, policy, or professional advice that applies to your situation. When a result depends on local rules, personal details, prices, or dates, enter those values yourself and confirm them before acting.

## Limitations and assumptions

- Results are estimates for informational purposes only and are not financial advice.
- Inputs outside the supported range are rejected rather than forced into a result.
- The result depends on the values you enter for this savings calculator; it does not supply missing rates, rules, prices, dates, or assumptions for you.
