How Investment Growth Is Calculated

Yearly Growth = Starting Balance × (1 + Return Rate) + Annual Contributions

Investment Growth Example

Example: £10,000 initial, £200/month, 5% annual return, 10 years

Year 1: ~£12,946
Year 5: ~£26,966
Year 10: ~£46,126
Total invested: £34,000
Total earnings: £12,126

The Power of Compound Interest

Year 1-5: Growth is steady but slower
Year 6-10: Growth accelerates as interest compounds
Year 10+: Exponential growth becomes visible
