Habit Cost Calculator
Any small, regular spend, a bought lunch, a taxi, a round of drinks, a subscription you barely use, costs far more than it feels like in the moment. Enter the habit to see its true weekly, annual and 10-year cost, and what redirecting it into savings could be worth.
Estimate only. This calculator gives estimates for information only, not financial advice. The invested-instead projection is illustrative, investment growth isn't guaranteed and actual returns will vary.

Why small habits cost more than they feel like
A single occurrence of a habit rarely feels significant, but multiplied across weeks, months and years the total can be startling, this is the classic MoneySavingExpert-style "Demotivator" effect. A habit costing just £5 a day comes to roughly £1,820 a year, and £9,100 over five years. Comparing it to a cheaper alternative, or investing the saving instead of spending it, turns everyday spending into a real, visible choice.
