Frequently asked questions
What if I miss my target?
Either save more, accept lower target, or extend the timeline. Don't increase risk just to chase the rate.
Is the 50/30/20 rule UK-applicable?
It's a US guideline (50% needs / 30% wants / 20% savings). Useful as a starting point but UK housing costs often eat more than 50% of income.
