Frequently asked questions
What counts as non-essential spending?
Things you could pause without affecting necessities: dining out, takeaway coffee, clothes, gadgets, impulse buys and unused subscriptions. Rent, food staples and bills are essentials and stay out of the cut.
Is the 5-year figure a forecast?
No - it's illustrative. It assumes you keep the saving habit and invest it at the return you enter; real returns vary and are not guaranteed.
Should I include money from decluttering?
Yes, if you plan to sell unwanted items. It's a one-off boost added on top of the recurring saving from spending less.
