Monopoly Trade Cash Gap Calculator

📖 Overview

Use this calculator mid-turn to verify whether a proposed trade keeps you above your survival cash buffer after current obligations.

Use these default and higher-pressure example inputs to explore how sensitive this calculator is before using your real numbers.

Calculates post-trade cash after immediate obligations and checks whether you stay above your target safety buffer.

The Formula

Ending Cash = Current Cash + Trade In − Trade Out − Immediate Payment

Trade In	Cash you receive in the proposed trade
Trade Out	Cash you pay to complete that trade
Immediate Payment	Rent/tax/card payment due right now
Target Buffer	Cash reserve you want after this turn

💡Use this before saying yes to a trade. A good trade can still kill your turn if it drops you under survival buffer.

Use this tool when you need a fast decision during active planning or execution.
Use this before committing money, time, or tradeoffs that are hard to reverse.
Use this to compare options using the same assumptions across scenarios.

Results can be misleading if key inputs are missing, stale, or unrealistic.
Very small or very large values may amplify rounding effects and interpretation risk.
If assumptions change mid-decision, recalculate before acting.

💡 Include all same-turn obligations, not only the trade cash exchange.

💡 Set a realistic buffer for worst-case next roll rent exposure.

💡 Re-check after every major deal because board risk shifts quickly.

❓ Why include target buffer?

Because a trade that leaves you at $0 can be technically legal but strategically fatal.

❓ Should I include incoming GO money?

Only if it is guaranteed before the next dangerous payment.
