Frequently Asked Questions
How does this differ from a standard compound interest calculator?
Instead of assuming a flat annual contribution, this tool increases your contribution amount each year by a fixed percentage, better reflecting rising income or salary raises over time.
When is interest applied relative to contributions?
In this model, your contribution is added at the start of each year and then interest is calculated on the full balance for that year.
What contribution increase rate should I use?
A common estimate is your expected annual raise percentage, often 3-7%, but you can adjust it to model any savings growth strategy.
