The Formula for Financial Growth
This calculator uses the future value of a series formula, which accounts for both an initial lump sum and regular, periodic contributions. It's the standard for accurately projecting savings growth.
A = P(1 + r/n)nt + PMT * [((1 + r/n)nt - 1) / (r/n)]
A = Future Value
P = Initial Principal
PMT = Periodic Contribution
r = Annual Interest Rate
n = Compounding Periods/Year
t = Number of Years

FAQs
1. What is the difference between simple and compound interest?
Simple interest is calculated only on the original principal amount. Compound interest is calculated on the principal amount as well as on the accumulated interest from previous periods. This "interest on interest" effect is what causes money to grow at an accelerating rate over time and is the key principle behind long-term wealth accumulation.
2. How does the "Savings Growth Schedule" work?
While a traditional amortization schedule tracks loan repayment, we've adapted the concept for savings. This schedule provides a detailed table that breaks down your savings growth month-by-month or year-by-year. It shows your starting balance, new contributions, interest earned for that period, and your new total balance.
3. Why are there so many different charts?
Each chart serves a unique purpose. The Pie Chart shows the composition of your final savings (principal vs. contributions vs. interest). The Line Chart visualizes the growth over time. The Bar Chart compares your annual contributions to the interest earned, highlighting when your money starts working for you. The Comparison Chart shows the dramatic difference regular contributions make.
4. Why is the currency symbol not in the text box?
The currency symbol is selectable from a dropdown for clarity. It is intentionally omitted from the input text box to prevent calculation errors that can occur from non-numerical characters. The correct currency symbol is automatically applied to all your results.
5. How can I maximize my savings with this tool?
This tool is perfect for exploring scenarios. Try increasing your regular contributions, even by a small amount, or extending your investment horizon. You can also see the impact of different interest rates. Visualizing these changes can motivate and inform better saving habits.
