Every product category has a payoff angle.
The Math is the Product
Every article follows the same formula: product cost, alternative cost, monthly burn rate, and one clear answer — the payoff date. No opinions. Just arithmetic.
We define the alternative
What does this product replace? Takeout? Store-bought razors? We find the ongoing cost of the status quo.
We run the numbers
Upfront cost ÷ monthly savings = breakeven. Then we stress-test it with different usage scenarios.
You get a single number
X months. That's your answer. Everything after that is pure savings — and we show you the chart to prove it.
