Most people get a raise, upgrade their life, and wonder why they feel no richer. Lifestyle inflation – or "creep" – is a quiet wealth destroyer. Enter your spending then vs. now – category by category – to see the exact cost and what it would be worth in your TFSA.
Lifestyle inflation is what happens when your spending grows as fast as your income, keeping your savings rate flat no matter how much you earn. This calculator breaks it down by category so you can see exactly where the creep happened, how much it's costing you each year, and what that money would be worth if it had gone into your TFSA instead. Takes about 5 minutes to fill in.

A $30K raise in Ontario can net as little as $17–19K after federal and provincial tax, CPP and EI. The gap between your gross offer and your real take-home is always larger than expected.
A nicer apartment. A car payment. DoorDash twice a week instead of once. Premium subscriptions. None of it feels like a decision. It just happens. Together, these absorb most or all of the raise.
$500/month in lifestyle creep, invested at 8% in a TFSA, becomes over $270,000 in 20 years, completely tax-free. That's the true cost of letting spending drift unchecked.
