Before you write
Why did my projection change?
Projections depend on the assumptions you enter. Check your starting balance, contribution amount, interest rate, inflation, and time period when comparing results.
Are these results guaranteed?
No. Escape Hatch explores hypothetical scenarios for education. Actual savings and retirement outcomes can differ from a projection.
