£200 per month is a sweet spot for many UK savers — enough to build real wealth without putting too much strain on your budget. At 7% annual returns, £200/month grows to roughly £162,000 over 25 years, with £60,000 contributed and £102,000 earned through compound interest. That means more than 60% of your final balance comes from growth, not your contributions. If you're already saving £100/month and considering doubling it, the difference is dramatic — an extra £81,000 over the same period.
