What return should I use in the calculator?
Use a conservative assumption and test more than one. The figure is yours to choose, because it is an assumption rather than a rate anyone can guarantee.
Does this account for inflation?
No. This one shows the nominal total. Use the real rate of return calculator to see what that total would actually buy.
Is investing monthly better than investing a lump sum?
They answer different situations. Monthly investing suits a salary and removes the question of timing, while a lump sum invests everything sooner. Module 02 explains the trade-off.
