Formula
Spendable cash equals the larger of zero or balance minus reserve. Affordable purchases equal whole spendable cash divided by the live cost.

Calculated locally
Factory purchase budget
Enter a non-negative balance and a live cost greater than zero.
The calculation stays in your browser and never asks for a Roblox login or account information.
Why the cost starts blank
Oil Tycoon prices can depend on the purchase and current progression. A blank field is safer than a value copied from another game or version.
What the tool cannot predict
It does not estimate production speed, sale revenue, offline output, worker performance, or the best purchase. Compare those results in the live factory.
Budget planning questions
What does the Oil Tycoon calculator do?
It divides the cash available after your chosen reserve by a live purchase cost and reports only whole affordable purchases.
Does it know every Oil Tycoon price?
No. Enter the cost shown in your current game so the result does not depend on an unverified or outdated value.
Does the result identify the best upgrade?
No. Use the factory guides to identify a bottleneck, then use this tool to check whether the chosen purchase fits your budget.
Does it need my Roblox account?
No. It uses only the numbers you type and runs locally in the browser.
