Questions about investment delay calculator
Why does waiting cost so much?
Money invested early has more years to compound, and the early years add the most to the final value.
What is the catch-up amount?
The monthly amount you would need to invest after the delay to end with the same final value as starting now.
Are the returns guaranteed?
No. The tool assumes a steady return that real investments will not follow exactly.
What waiting costs
Investing 500 a month at 7% for 30 years grows to about 609,985. Starting five years later leaves 405,036, and starting ten years later leaves 260,463. The ten-year wait costs about 349,522, even though it removes only 60,000 of deposits. Early money has the longest to compound.
| Wait | Final value | Cost of waiting | Monthly amount to catch up |
|---|---|---|---|
| Start now | 609,985 | 0 | 500.00 |
| 1 year | 563,084 | 46,902 | 541.65 |
| 2 years | 519,344 | 90,641 | 587.27 |
| 5 years | 405,036 | 204,950 | 753.00 |
| 10 years | 260,463 | 349,522 | 1,170.96 |
| 15 years | 158,481 | 451,504 | 1,924.47 |
Why catching up is hard
To end with the same 609,985 after a ten-year wait, you would have to invest 1,170.96 a month, about 2.3 times the original amount. The shorter the time left, the more each monthly deposit has to do on its own.
Deposits are made at the end of each month at a steady return. Real returns vary, and the tool leaves out tax and fees. It compares two plans and is not a forecast of what you will have.
Stopping early is different from starting late
Time at the start is worth more than time at the end. Starting ten years late means 20 years of deposits and leaves 260,463. Depositing for the first 20 years, then stopping and leaving the money invested for the last 10, puts in the same 120,000 and ends with about 523,443.
Starting small also beats starting late. 250 a month from today ends with about 304,993, more than the 260,463 from 500 a month begun ten years later. You can raise the amount as you go.
