Is This Worth It? The Calculator for Every Purchase You're Second-Guessing

By David Brown · April 2026 · 3 min read

Before every significant purchase, there's a moment of hesitation. Is this worth it?

The question is real but usually stays vague. Our worth-it calculator makes it specific.

Price in Hours of Work

Convert any price to hours of work at your after-tax hourly rate. A $400 purchase on a $50,000 salary ($24/hour after tax) costs 17 hours of your working life.

That framing doesn't make the purchase wrong. But it creates an honest comparison: is this thing worth 17 hours of my time?

The Cost-Per-Use Method

For durable goods — appliances, clothes, tools, electronics — the relevant metric is cost per use, not sticker price.

A $120 jacket you wear 150 times costs $0.80/wear. A $40 jacket you wear 8 times costs $5/wear. The expensive jacket is cheaper in the metric that actually matters.

Before buying anything you'll use repeatedly, estimate your realistic use frequency. Divide price by expected uses. Compare to alternatives.

When "Worth It" Math Fails

Pure cost-per-use reasoning misses the value of experience purchases. A vacation, a concert, a meal at a special restaurant — these have value that doesn't reduce to cost-per-hour or cost-per-use. Joy, memories, relationships aren't well-captured by the calculator.

Use the calculator for purchases where value is primarily functional. For experience purchases, the relevant question is whether you'll regret not doing it — which is a different calculation entirely.

Frequently Asked Questions

How do I calculate my after-tax hourly rate for the calculator?

Take your annual salary, subtract taxes and deductions to get your actual take-home pay, then divide by the number of hours you work per year (typically 2,000 for full-time). For example, a $50,000 salary with taxes leaves roughly $38,000 take-home, which divides to about $19/hour. The calculator uses this real hourly rate, not your gross salary, because it shows what you're actually giving up in working time.

Should I use cost-per-use for every type of purchase?

Cost-per-use works great for functional items like jackets, tools, and appliances where you can realistically estimate how many times you'll use them. Skip this method for experience purchases like concerts, vacations, or meals—these have value in memories and joy that doesn't reduce to a per-use number. The calculator is most useful for durable goods where frequency actually determines whether something is a bargain or waste.

How do I estimate realistic use frequency so my cost-per-use calculation is accurate?

Be honest and conservative—most people overestimate how often they'll use things. Think about the last 6-12 months of similar items you owned: How many times did you actually use them? For a $120 jacket, don't assume you'll wear it 200 times just because it's nice; if you wore previous jackets 150 times, use 150. Underestimating use frequency is better than the reverse, since you're trying to avoid false bargains.

What's the difference between using the hourly-work method and cost-per-use?

The hourly-work method answers "How much of my life does this cost?" and works for any purchase—it's purely price-based. Cost-per-use answers "Is this a better deal than alternatives?" and only works for items you'll use multiple times. A $400 item costs 17 hours of work regardless, but a $400 coat might be cheaper per wear than a $120 coat if you'll wear it enough times. Use hourly-work for gut checks on any price; use cost-per-use when comparing similar durable items.
