Time is doing most of the heavy lifting. Compare a five-year longer horizon before increasing the return assumption.
Sensitivity check

Formula
Monthly compounding is applied to the existing balance, followed by the monthly contribution.
The projection treats the entered annual return as an effective annual return and converts it to the mathematically equivalent monthly rate. Contributions are added at the end of each month, with no tax, fee, or inflation adjustment.
Editable rates, growth assumptions, prices, fees, and percentages are planning inputs unless the calculator explicitly identifies a current source.
