The annual rate is treated as a nominal rate divided by the selected compounding frequency, then converted to an equivalent monthly factor. Contributions occur at the selected beginning or end of each month. Returns can change and are not guaranteed; taxes, fees and inflation are not deducted.
Estimate only. Actual lender or investment results may differ; this is not financial advice.

How this tool works
The projection compounds the opening balance and adds recurring contributions over the selected term, separating contributions from estimated growth.
Limits to know
The projection assumes the entered return and contribution timing remain constant. Market returns, account fees, taxes, inflation, and changing deposits are not predicted.
