Why compounding rewards starting early
Worked example: contributing £200 a month at an assumed 6% a year for 25 years builds a pot of roughly £139,000, of which around £79,000 is investment growth rather than money paid in — see the exact split for your own numbers above. The earlier contributions start, the longer they have to compound.
