Quartz costs $250 more to install ($3,750 vs $3,500) but needs no upkeep. The $25/yr granite resealing erases that install saving by year 10, then quartz edges ahead, a near dead heat decided by maintenance.
Inputs
Result
Over just 5 years granite pays only $125 in resealing (5 x $25), so its lower install keeps it cheaper at $3,625 vs $3,750. Break-even is year 10, so if you will remodel or sell before then, granite is the value pick.

Doubling resealing to $1/sqft/yr ($50/yr) pushes granite to $4,500 over 20 years. The no-maintenance quartz now saves $750 and break-even halves to year 5, the more you reseal, the more quartz wins.
For a typical 50 sqft kitchen in 2026, quartz installs at about $75/sqft ($3,750) and granite at about $70/sqft ($3,500), near-parity up front. Quartz is non-porous and needs zero maintenance, while granite needs periodic resealing of roughly $0.50/sqft a year ($25/yr for 50 sqft). That $250 lower install on granite is erased by resealing around year 10, after which quartz is cheaper: about $3,750 vs $4,000 over 20 years. Granite wins for short holds under ~10 years or if you skip resealing; quartz pulls ahead the longer you keep the counters.
It is close. Quartz and granite cost about the same to install, roughly $70 to $75 per square foot, or $3,500 to $3,750 for a 50 sqft kitchen. The lifetime difference is maintenance: quartz is non-porous and never needs sealing, while granite needs periodic resealing at roughly $0.50/sqft a year ($25/yr here). Over 20 years quartz totals about $3,750 versus $4,000 for granite, so quartz wins by around $250, but only after the break-even at year 10. For shorter holds, the lower granite install keeps it cheaper.
| Material | Installed (50 sqft) | Resealing / yr | 20-Year Total |
|---|---|---|---|
| Quartz | $3,750 | $0 | $3,750 |
| Granite (sealed) | $3,500 | $25 | $4,000 |
| Granite (never sealed) | $3,500 | $0 | $3,500 |
Break-even is when the granite resealing you keep paying catches up to the slightly higher quartz install. Divide the install gap by the yearly resealing: a $250 gap (quartz $3,750 vs granite $3,500) divided by $25/yr of resealing is 10 years. Reseal more often or pay a pro and the gap closes faster, at $1/sqft/yr ($50/yr) break-even drops to year 5. Because countertops easily last 20 to 40 years, a break-even near year 10 means quartz is usually cheaper for anyone staying put, while granite wins for a quick flip.
Quartz never needs sealing, the resin binder makes it non-porous, so its upkeep is always $0. Granite is natural stone and porous, so it is sealed to resist stains. How often depends on the slab: dense, dark granite can hold a sealer for 3 to 5 years or longer, while light, porous granite may want resealing every year. DIY sealer runs about $1 to $2 per sqft; a pro visit is $200 to $400. If your granite is dense and rarely needs sealing, its upkeep approaches $0 and it stays the cheaper choice; if it is porous and you reseal yearly, quartz pulls ahead faster.
On lifetime cost it is nearly a tie, so the choice usually comes down to use and taste, not dollars. Quartz wins on convenience: consistent color, no sealing, and strong stain resistance, though it can scorch under hot pans and may fade in direct sun. Granite wins on heat and UV tolerance, making it the better pick for outdoor kitchens or south-facing windows, and every slab is unique. Both resist scratches and last decades. Pick quartz if you want zero maintenance and a uniform look; pick granite for natural variation, heat resistance, or a short hold where its lower install price wins.
