Around the house
Before you sign with a contractor, or pay for a service call.
- Most-used tool Is my HVAC quote fair? A line-by-line read of your quote against real 2026 price bands, with a verdict gauge showing exactly where your number sits: fair, high, or way off.
- Should I repair it or replace it? Walk the actual decision: when one more repair is throwing good money after bad, and when replacing is the contractor's idea, not yours.
- Why does one room never get comfortable? The handful of real causes behind the room that's always too hot or too cold, and which fixes are cheap versus which a pro should touch.
Does this actually pay off?
Six break-even tools on the same honest math. They'll tell you when not to buy.
- Would a home coffee setup pay for itself? Your real annual café spend versus brewing at home, plus the month the machine breaks even, or whether, at your volume, it never does.
- Does charging an EV at home beat gas? What a full charge actually costs on your electricity rate, side by side with what those miles would cost in gas, and what a home charger adds.
- What is a water filter really costing me? The upfront price is the small part. Count the replacement cartridges over a few years, then weigh it against bottled. The gap is the decision.
- What does that mattress cost me per night? A $1,400 bed you sleep on for eight years is cheaper per night than a $500 one you replace in three. See the number that actually matters.
- What will my desk setup cost, all-in? Desk, chair, monitor, arm, the bits that sneak up. Add them up honestly before you start buying, so the total isn't a surprise.
- Is my dog's supplement worth the money? What you're really paying per day per dose, and whether the label backs it up, so you keep the ones that earn it and drop the ones that don't.
How this works
There's no email wall and nothing to buy to get the answer. Each tool shows its math and its assumptions right next to the result, so you can check the logic instead of trusting a claim.
And the answer is allowed to be "don't." When the numbers say a purchase isn't worth it, the tool says so. If the math says don't, we say don't. Browse everything on The Boring Thing →
