Higher rate (40%)	£7,500*	£12,500

What About Lump Sum vs Monthly?

Lump Sum

Pros	Cons
Time in market (statistically better)	All at once (psychologically harder)
Immediate growth	May invest at peak

Monthly Investing

Pros	Cons
Pound cost averaging	Some money not invested
Easier psychologically	May miss early growth
Reduces timing risk	Takes longer to fully deploy

The Answer

Both work. Statistically, lump sum wins more often. Emotionally, monthly might feel safer. Choose what you’ll actually do.

Investment Examples

£10,000 Growth Scenarios

Annual Return	After 5 Years	After 10 Years	After 20 Years
3% (cash-like)	£11,593	£13,439	£18,061
5% (balanced)	£12,763	£16,289	£26,533
7% (stocks avg)	£14,026	£19,672	£38,697
10% (growth)	£16,105	£25,937	£67,275
