About This Calculator
The Savings Calculator helps you project how much your savings will grow over time with compound interest and regular monthly contributions. Whether you're planning for retirement, a down payment, or a major purchase, this tool shows you the power of consistent saving.
This calculator accounts for your initial deposit, monthly contributions, and compound interest to show your projected savings balance. See how small regular contributions can grow significantly over time with compound interest working for you.
Formula & Calculation Method
Savings with Compound Interest Formula:
Future Value = Initial Deposit × (1 + r)^n + Monthly Deposit × [(1 + r)^n - 1] / r
Where:
r = Monthly interest rate (Annual rate / 12)
n = Number of months (Years × 12)
Interest Earned = Future Value - Total Deposited
The formula compounds interest monthly on both your initial deposit and monthly contributions. This shows the true growth potential of regular savings with compound interest.

Frequently Asked Questions
How often is interest compounded?
This calculator assumes monthly compounding, which is common for savings accounts. The interest is applied monthly to both your initial deposit and accumulated monthly contributions.
Can I change my monthly deposit amount?
The calculator uses a fixed monthly deposit for simplicity. In reality, you can adjust your contributions, but this gives you a baseline projection.
What if I want to save weekly or bi-weekly?
For weekly savings, multiply your weekly amount by 4.33 (average weeks per month). For bi-weekly, multiply by 2.17. Then use that as your monthly deposit.
How accurate are these projections?
Projections assume constant interest rates and regular contributions. Actual results may vary based on market conditions, rate changes, and your ability to maintain consistent deposits.
