How to use the Savings Calculator
Project how an initial balance may grow with monthly contributions and an annual interest rate over a chosen number of years.
Formula / calculation logic
The tool applies monthly compounding to the starting balance and adds the future value of recurring monthly contributions.
Worked example
Starting with 1,000, adding 200 each month and applying a 4% annual rate for 5 years produces a projected balance based on monthly compounding.
Important notes
This is a projection, not a promise of investment returns. Real accounts may compound differently and may include taxes, fees or variable rates.
Frequently asked questions
What if the interest rate is 0%?
The result becomes the starting balance plus all monthly contributions.
Are deposits assumed at the start or end of each month?
Recurring contributions are treated as end-of-period contributions in this implementation.
