Frequently Asked Questions
What is compound interest?
Compound interest means you earn returns on your returns as well as your original investment. Over long periods, this creates exponential growth — the longer you invest, the more powerful the effect.
Should I invest a lump sum or drip-feed?
Historically, lump sum investing has outperformed drip-feeding about two-thirds of the time, because markets tend to rise over time. However, drip-feeding (pound-cost averaging) reduces the risk of investing everything at a market peak.
