200 purifier over 5 years = 40 amortised. Add 60 annual filter replacements and 30 electricity = 130 annual operating cost. Compare against allergy relief, asthma reduction, or general air quality value. Cost is clear; benefit varies person to person.
Run it with sensible defaults
Using purchase price of 200, expected years of 5, annual filter cost of 60, annual electricity of 30, the calculation works out to 130.00. Nudge the inputs toward your own situation and the output recalculates instantly. The defaults are meant as a starting point, not a recommendation.
The levers in this calculation
The inputs — Purchase Price, Expected Years, Annual Filter Cost, and Annual Electricity — do not pull with equal force. Not every input has equal weight. Flip one at a time toward extreme values to feel which ones move the needle most for your situation.
How the math works
Purchase amortised plus annual consumables and electricity. The working is transparent — you can verify every step yourself in the formula section below. No black box, no opaque "proprietary model".
When the result says "wait"
If the payback is longer than you expect to keep the item, the math says no. That's useful information — not everything has to earn its keep financially, but knowing when something doesn't means the decision to buy it anyway is deliberate.
What this doesn't capture
Purchase decisions rarely come down to payback alone. Reliability, time saved, enjoyment, and alternatives outside the calculation all matter. The figure gives you the money side cleanly so you can weigh it against everything else honestly.

Running two or three together exposes inconsistencies in any single assumption — which is usually where the useful insight lives.
