Frequently Asked Questions
Why does compounding accelerate later?
As corpus grows, returns are earned on previous returns, creating exponential growth over longer durations.
Is monthly contribution more important than return assumptions?
Both matter. Consistent contribution often has a large impact, especially in early years.
Should I plan with conservative returns?
Yes. Using realistic return assumptions improves planning reliability and reduces future shortfall risk.
