A premium blade costs 2-3x more than a budget blade. Is the upgrade worth it on YOUR job? Enter your numbers below — blade price, expected linear feet, slab conditions — and the calculator returns dollars-per-cut, dollars-per-linear-foot, and the ROI of stepping up to the next blade tier.

Your Job Parameters

Job conditions

Life ranges and adjustment factors are our editorial estimates, not manufacturer ratings. Your aggregate, saw, and operator technique move these numbers — treat results as a comparison tool between tiers, not a quote.

How This Calculator Works

Blade life is the variable that dominates per-cut cost. A $70 budget blade that lasts 150 linear feet costs $0.47/foot. A $160 premium blade that lasts 500 linear feet costs $0.32/foot — cheaper per foot AND with fewer disposal swaps.

The adjustments matter. Wet cutting roughly doubles blade life vs dry — that's the single biggest lever. Heavy rebar costs ~40% of blade life. Hard aggregate (granite, trap rock) costs another ~25%. The calculator stacks these adjustments multiplicatively.

The "adjusted blade life" output is your blade-life input modified for job conditions and cut depth. Life ranges are referenced to a 4″ cut depth — deeper cuts consume more diamond per linear foot, so at 6″ the calculator scales life down by a third. One cut = one linear foot at your stated depth, so $/cut and $/linear-foot read identically by design.

Common Buying Decisions

Ultra Value vs Premium Sparkie: on clean cured slab, the Ultra Value ($69.99) usually wins on per-foot cost — run the numbers above. The Sparkie ($174.30) earns its price on rebar-heavy and hard-aggregate work, where its self-dressing bond holds life while the entry blade glazes and loses ~40%.

Sparkie vs Husqvarna Elite-Cut S85: the Elite-Cut is dealer-distributed (typically $200-260, no Amazon listing) and pencils only at sustained daily production. Run both through the calculator with your own footage before paying dealer premium.
