A lump sum gives the full amount more time to grow. If the return is positive, investing earlier can create a higher future value than waiting.
This is one reason time is so important in compound interest examples.
Monthly investing builds discipline
Many people do not have a large lump sum. Monthly investing can still be powerful because it turns saving into a habit.
Regular contributions also make planning easier because they can align with income and budgeting cycles.
The best approach depends on the situation
A lump sum may be useful when money is already available. Monthly contributions may be more realistic for ongoing savings.
The calculator supports both by allowing an initial deposit and recurring contributions.
