Cost of Waiting to Invest
Compare investing regularly starting today versus delaying your monthly contributions. See how many future dollars you give up by waiting and how much extra you would have to save later to catch up.
Assumptions
You're still investing your existing starting balance the whole time. Only new monthly dollars are delayed.

Bars show how much of your future balance comes from dollars you put in versus market growth. Waiting reduces both contributions made and years of compounding.

By waiting 5.0 years to start monthly investing, you give up roughly $539,333 (36.2% of what you could have had) at the end of the 30.0-year horizon.
What it takes to catch up
If you wait 5.0 years but still want to end up with the same future value as “Invest now,” you'd need to increase your monthly contribution after you finally start.
- Current planned monthly (when you do start): $1,000
- Required monthly after waiting to fully catch up: $1,567
- Extra per month you'd need to find: $567
The longer you delay, the harder it becomes to close the gap later without significantly higher savings.
Plain-language Summary
- • You're planning to invest for 30.0 years at about 8.0% annual return.

- • That delay costs you around $539,333 in future wealth, most of which is lost compounding on contributions you never made.
