Compare a trade
Enter the values you trust for both sides, choose your own tolerance, then review the signed, absolute, and percentage differences.
Trade Weapons Calculator
Compare a trade, project income, or test box chance. Enter your own values, income rates, and probabilities—nothing is prefilled from an unverified database.
Quick start
Choose a calculator
Start with the task you need. Each result is pure math based on your inputs.
Three working client-side modules calculate trade difference, income projection, and repeated-chance scenarios from player-entered numbers while exposing all formulas and assumptions. Interactive two-sided offer input with totals, difference, percentage, and user-threshold scenario label.
The income module converts a user-entered per-second rate across a chosen time and compares it with an optional target. The income module converts a player-entered per-second rate across time and optional targets. The income section helps compare a current and target per-second rate without inventing upgrade costs.
The trade calculator totals each side and labels the result without claiming official item values. Box chance simulator requires a user-supplied probability and attempt count, shows at-least-one or none outcomes, and keeps the independence assumption visible.
Tool A
Trade Difference
Compare totals, signed and absolute gaps, and a percentage against your-side total.
Tool BIncome
Project earnings over time or estimate how long your rate takes to reach a target.
Tool CBox Chance
Calculate at-least-one probability or reverse-calculate boxes for a target chance.
This calculator does not provide an official Trade Weapons value list.

Trade, income, or box probability
Enter your own values, income rates, or box odds. No weapon names, prices, rates, or probabilities are preloaded.
Tool A
Trade Difference Calculator
Add the values you trust for each side. The tool compares totals; it does not supply a value list or a trade verdict.
Based on your inputs
Your total

Their total

Signed difference
+0
Positive means their entered total is higher.
Absolute difference

Calculated from your chosen percentage.
Enter valid values on both sides
This is arithmetic using your threshold, not an official value, fair-trade standard, or W/F/L verdict.
How to use
How to Use the Trade Weapons Calculator
Use the calculator for arithmetic; use the trading guide for the wider decision workflow.
Plan income
Enter an observed income-per-second rate. Use a duration for projected earnings, or current and target balances for time-to-target.
Test box probability
Enter a single-box probability and whole-number attempt count. Add a target percentage when you need the reverse calculation.
Evidence boundary
Your inputs are not an official value database
Use values, rates, and probabilities you have observed or trust. This page does not preload weapon names, market prices, rarity, income rates, demand, box odds, or an official W/F/L threshold.
Page boundary
Math here; trade workflow in the guide
This page owns calculations. The trade guide covers how to organize an offer and keep uncertainty visible; the tier-list page remains evidence constrained.
FAQ
Trade Weapons calculator questions
What is the Trade Weapons calculator?
It is a fan-made set of three user-input math tools for comparing trade totals, projecting income, and testing box probability scenarios.
Does this calculator provide official weapon values?
No. It has no verified official weapon value database and performs calculations only with values you enter.
How do I compare two Trade Weapons trades?
Enter one or more values for each side. The tool totals both sides and shows signed, absolute, and percentage differences using your-side total as the percentage baseline.
How do I calculate income in Trade Weapons?
Enter an income-per-second rate you trust. Add a duration for projected income, or add current and target balances to estimate time to the target.
How does the box chance calculator work?
It calculates one minus the probability of failing every attempt: 1 − (1 − p)^n. The model assumes the chance stays the same and attempts are independent.
How many boxes do I need for a target chance?
Enter a per-box probability and target percentage. The reverse calculation returns the minimum whole number of boxes when a finite result exists.
Are the box odds built into the calculator?
No. Trade Weapons odds, pity, replacement, and independence rules are not verified here, so you must supply the probability.
Can I use my own weapon values?
Yes. Use one consistent, dated value basis for both sides and remember that the arithmetic does not measure demand, authenticity, or every trade factor.
