Limited Sniping ROI Calculator

Before you hit buy on that undercut, check if the snipe still prints after Roblox takes its cut. See ROI, profit, break-even, and your max safe buy price.

Use the price you realistically think you can sell for (recent average sale or RAP minus undercut), not the dream highest sale.

ROI here is based on the Robux you are risking on the snipe (buy price). 25% ROI means you want 25% profit on top of what you spent, after tax.

If you pay more than this at the current expected sell price, you're losing Robux after tax.

Max buy for ~25.00% ROI

7,840 R$

To hit your target ROI after tax at this sell price, don't pay more than this for the snipe.

This is profitable but doesn't hit your target ROI. You're clearing 8.89% vs your goal of 25.00%. Either snipe lower or be realistic about your sell price.

Roblox limited snipe check: Snipe at 9,000 R$ → expect to resell for 14,000 R$ with 30.00% marketplace tax. After tax I get 9,800 R$ and make 800 R$ (+8.89% ROI, Solid (reasonable snipe)). To hit ~25.00% ROI, I shouldn’t pay more than 7,840 R$. Checked with ToolBLX Limited Sniping ROI Calculator: https://toolblx.com/tools/limited-sniping-calculator

How this works

The calculator assumes you snipe a limited at buy price, then later sell it for your expected sell price. Roblox takes a cut on the sell:

net_after_tax = expected_sell × (1 − tax%) profit = net_after_tax − buy_price ROI% = profit ÷ buy_price × 100

To find the max buy price for break-even, we set profit = 0:

0 = net_after_tax − max_buy max_buy_break_even = net_after_tax

For a target ROI%, we solve:

ROI_target = (net_after_tax − buy) ÷ buy ⇒ net_after_tax = buy × (1 + ROI_target) ⇒ max_buy_for_target = net_after_tax ÷ (1 + ROI_target)

That's what lets the tool say "don't pay more than X R$ for this snipe if you want Y% ROI". It's all rough and based on your inputs, but it gives traders a fast sanity check before they slam buy on an undercut.
