Buy It For Life, Or Buy It Twice: A TCO Worksheet You Can Actually Use
A blunt TCO (total cost of ownership) worksheet that turns shopping into math so you stop funding marketing and start buying freedom. Don’t chase sales; crush costs. A ruthless way to choose repairable, efficient gear—and dodge the expensive thrill of buying twice.

We don’t just buy objects; we buy futures. Every tool carries an invisible budget of repairs, energy, time, and attention. Markets package that future as “new,” “pro,” or “limited.” Your job is simpler and colder: calculate the total cost of ownership (TCO) and choose the path that compounds freedom. In plain English: if an item can work hard for a decade, buy it once. If not, you’ll rent it from entropy—and pay twice.
TCO is how quiet money shops. It replaces the dopamine loop (“ooh, new!”) with arithmetic (“does it lower lifetime cost and risk?”). The tactic isn’t ascetic; it’s strategic. You’re not collecting objects, you’re engineering optionality—owning fewer, better tools that create time rather than consume it.
The 10-Minute TCO Worksheet (copy this into Notes or a spreadsheet)
Define the job. What must this tool do at a minimum for five to ten years? List non-negotiable specs and the environment (daily use, outdoors, kids, heat, dust).
Set a floor. Anything that can’t meet the job with margin is out—no matter how cheap.
Now fill the inputs:
Purchase Price (P) + required Accessories (A) + Setup/Training (S).
Energy/Consumables per Year (E): power, filters, blades, detergent.
Maintenance per Year (M): service, parts, cleaning.
Expected Repairs (R): probability × cost (e.g., 20% × $150 = $30/year).
Time Cost (T): minutes lost or saved per week × 52 × your value/minute.
Financing Cost (F) if you’re not buying cash.
Resale/Trade-in (V) at end of life (negative cost).
Lifespan (L) in years under your actual use.
TCO/year = [(P + A + S) + L×(E + M) + L×F + L×R − V − L×T] ÷ L
TCO/hour = (TCO/year) ÷ (hours of use per year).
Decision rule: pick the option with the lowest TCO/year or TCO/hour that clears the job floor.
A quick example: the office chair you live in
Cheap chair: P=$200, L=3, E/M/F/R ≈ 0, T= +10 lost minutes/week, value/min=$0.25.
T per year = 10×52×0.25 = $130. TCO/year = (200 ÷ 3) + 130 ≈ $196.BIFL chair: P=$900, L=12, good mechanics, T = −20 minutes/week (time saved).
T per year = −20×52×0.25 = −$260. TCO/year = (900 ÷ 12) − 260 = 75 − 260 = −$185.
Reality check: you’re paying either way—money or minutes. If the “expensive” chair returns focus and removes micro-injury, it’s cheaper per year and priceless per spine.
Five ruthless rules that keep you honest
Buy for lifespan, not launch date. If it won’t reasonably cross five years in your conditions, it’s rental gear.
Prefer repairable designs. Screws beat glue, parts availability beats press releases, warranties that name parts beat vibes.
Value silence and uptime. Noise, wobble, crashes, and recalibrations are hidden taxes. Quiet reliability is a dividend.
Punish energy hogs. A “cheaper” appliance can lose to an efficient one within two winters. Price the watts.
Pay once for ergonomics. Comfort compounds; pain compounds faster. If a tool touches your body for hours, bias toward BIFL.
Spotting fake “buy it for life”
Lifetime warranties that cover zippers but not stitching.
Proprietary parts no one stocks after year three.
Coatings that peel under heat or sun.
Reviews that praise unboxing more than year-two performance.
Brand “heritage” with outsourced quality control.
How to use this in the wild
At the store or product page, run a three-question blitz:
What’s the weakest component, and how is it replaced?
What’s the realistic lifespan in my environment? Show me proof.
If it dies year two, what’s my exit—repair, resale, or manufacturer swap?
Then do the math. If the premium option drops TCO/year and clears the job floor, buy once, cry once. If not, walk. There will always be another sale; there may not be another you.
Bottom line: The world will sell you infinite novelty. Your job is to buy finite tools that make better days. TCO is your filter against regret and landfill. Use it, and your home becomes a lab where time, money, and attention compound in your favor. That’s the quiet luxury: fewer things, longer lives, better hours.
Spreadsheet columns to copy: Item, Job floor notes, P, A, S, E/year, M/year, R/year, F/year, L (years), V, T per year, Hours/year, TCO/year, TCO/hour, Decision, review date. Stick it near your cart and force numbers to talk. Here is a free TCO worksheet to get you started.
