Formula and Logic
This calculator uses the future value of an annuity formula for monthly contributions and compound interest for the initial deposit. The monthly rate is annual rate divided by 12, and the future value is summed over all months. Effective annual rate accounts for compounding frequency.
Practical Notes
- Interest rates from banks can vary; compare high-yield savings accounts for better returns.
- Compounding frequency matters: monthly compounding yields more than annual.
- Tax implications: Interest earned may be taxable; consider tax-advantaged accounts like IRAs.
- Budgeting habit: Automate contributions to maintain consistency and reach goals faster.

Frequently Asked Questions
What if my interest rate changes over time?
This calculator assumes a fixed rate. For variable rates, run separate calculations for each period or use an average rate estimate.
Can I include irregular contributions?
Currently, only regular monthly contributions are supported. For irregular amounts, consider using a spreadsheet or adjusting the monthly average.
How does inflation affect my savings?
This tool does not adjust for inflation. For real purchasing power, subtract an estimated inflation rate from the interest rate in your calculations.
