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, and every one of them is this site's planning assumption, not a measured or manufacturer figure. The calculator doubles planning life for wet cutting against dry, the single biggest lever. It takes about 40% off for heavy rebar and about another 25% for hard aggregate (granite, trap rock), and it 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 work, which VA lists among its uses. The calculator takes about 40% off planning life for heavy rebar, whatever the blade.

Sparkie vs Supreme Pro: VA ranks its Supreme line above its Premium line and sells the Supreme Pro ($104.88) for concrete and asphalt on one blade. VA publishes no life figure for it, so enter your own footage before comparing the two.
