A $65 Electric Shaver Pays for Itself in 4.5 Months
Cartridge razors and shaving cream run about $15/month — more if you're buying the fancy 5-blade refills. An electric shaver drops that to roughly $0.50/month in electricity and replacement parts. That's one of the fastest payoffs we've ever calculated.

The Setup: Death by a Thousand Tiny Cartridges
Nobody wakes up and decides to spend $180 a year on shaving. It just sort of… happens. A 4-pack of cartridge refills here, a can of shaving cream there. Each purchase feels small — maybe $12 to $18 at the drugstore — but they stack up month after month after month. It's the subscription you never signed up for.
An electric shaver flips that equation. You pay once upfront, plug it in (or charge it), and the recurring costs nearly vanish. The only ongoing expense is a replacement foil or blade head roughly once a year — about $30 to $40 — which averages out to around $0.50/month when you spread it across its lifespan. No cream, no cartridges, no standing in the shaving aisle wondering why four tiny blades cost more than lunch.
The Math
We're comparing a mid-range electric shaver at $65 against the typical monthly spend on disposable or cartridge razors plus shaving cream at ~$15/month. The electric shaver's running cost is ~$0.50/month (electricity plus annualized replacement foils). That's a net savings of about $14.50/month, which means the shaver pays for itself in roughly 4.5 months.
After that breakeven point, you're pocketing approximately $174 per year. Keep the shaver for three years — well within a typical lifespan — and that's over $500 back in your pocket from a single $65 purchase.

Cumulative Cost Over Time
The lines cross at the breakeven point — that's when the savings zone begins.
When This Doesn't Pay Off
Let's be honest: electric shavers aren't for everyone. If you need a perfectly smooth, baby-face-close shave for work or personal preference, most electrics still can't match a fresh multi-blade cartridge razor against the skin. You might find yourself keeping a pack of disposables around for special occasions anyway, which chips into the savings. Some people also experience skin irritation when switching to electric — it can take 2–3 weeks for your skin to adjust, and for a small percentage of folks, it never quite works out.
The math also assumes you're currently buying name-brand cartridges at retail prices. If you've already hacked your shaving budget with a safety razor ($0.10/blade), a subscription service, or bulk-buying store-brand cartridges, your baseline spend might be well under $15/month — which stretches the payoff period or shrinks the annual savings. And if you only shave once or twice a week, your cartridges last longer than average, so the disposable cost we modeled may be too high for you.
Finally, not all electric shavers are created equal. A cheap $25 model might frustrate you into abandoning it within weeks, while an expensive $200+ model pushes the breakeven out far enough to make you question the whole exercise. The sweet spot — a solid mid-range shaver in the $40–$80 range — is where the math really sings.

The Philips Norelco 3900 at $80 adds a charging stand to the 3600's feature set, which keeps the shaver upright and always topped off. The breakeven stretches to about 5.5 months — still fast — and you're paying for a small daily-use convenience upgrade. Worth it if you like your countertop tidy and your shaver always ready to go.

What we didn't account for
- → Shave frequency matters Our math assumes daily or near-daily shaving. If you only shave 2–3 times a week, your disposable cartridges last longer, which lowers your baseline cost and extends the payoff window.
- → Replacement heads vary in cost We averaged replacement foil/blade costs at ~$30–40 per year, but prices vary by model. Premium shavers sometimes require pricier replacement heads, which can nudge up the monthly running cost.
- → Electricity cost is estimated We assumed a negligible electricity cost for charging. If you're in a high-rate area, it's still pennies — but we didn't model your exact utility rate.
- → No resale or switching costs We didn't account for the cost of any shaving cream or aftershave you might still buy alongside the electric shaver, nor any residual cartridge packs you've already purchased sitting in your cabinet.
