Rust Upgrader Quote Audit
Check what one displayed upgrader quote implies—using your values, transparent formulas and no operator recommendation.
Audit one displayed quote
Use the same balance unit and timestamp. Optional cash values unlock the cross-market comparison.
- Cash-equivalent RTP and valuation spread need both external cash values; no missing value was estimated.
The browser performs the arithmetic and creates exports locally. Analytics records only that the tool or export was used—never the values entered above.
What the calculator measures
The fair value-ratio chance is source site value ÷ target settlement value, capped at 100%. Implied site-credit RTP multiplies the displayed probability by target settlement value and divides by source value. Expected loss per 100 is 100 minus that implied RTP.
When both external cash values are supplied, the tool repeats the expected-return calculation in those cash units. The valuation spread compares site credits per external-cash unit for the target with the same ratio for the source.
Worked example
A 50-unit source, 100-unit target, 47.5% displayed chance and 1.00 settlement multiplier produce a 50% value-ratio chance and 95% implied site-credit RTP. The expected loss is 5 units per 100 under those exact inputs. This example illustrates arithmetic; it is not a live quote or expected session result.
Assumptions and limitations
- Source and target site values must use the same balance unit and observation time.
- External cash values must refer to comparable realizable values, not a mix of Steam Wallet asking price and cash-market proceeds.
- A settlement multiplier changes the target liability; use 1.00 unless the applicable official rule documents another value.
- The tool does not inspect server code, randomness, custody, account restrictions, inventory or settlement performance.

Responsible-play context
Expected value describes a long-run average under fixed assumptions. A single result can be a complete loss, and repeating a negative-expectation quote increases expected total loss. Set limits before play and do not treat a calculated chance as a recovery strategy.
One quote, two value bases
Hypothetical example, not an operator quote.
A 10-credit source, 20-credit target and 45% chance imply 90% return in site credits. If the source is worth 8 in cash and the target 14, cash-equivalent return is 78.75%. Fees and stock constraints are excluded.
