The Formula

💡Classic Monopoly typically uses 10% interest to unmortgage.

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.

💡 Use 10 for interest rate in standard rules unless house rules differ.

💡 Prioritize unmortgaging high-rent strategic sets first.

💡 Run a best-case, base-case, and worst-case scenario before deciding.

💡 Use recent real values, not ideal assumptions, for better accuracy.

❓ Can I use this for multiple properties at once?

Yes, set property count to the number you plan to unmortgage now.

❓ Is this deterministic?

Yes, this is exact rule arithmetic, not a projection.
