Monthly budget comparison calculator
Compare two monthly budgets you have assembled from actual quotes or your own spending records. The calculator shows their baht difference and percentage difference relative to budget A. It does not maintain city price tables or rank Thai cities. Use matching household size, housing type and cost categories for a useful comparison.

Difference = B − A. Relative difference = (B − A) ÷ A × 100%.

What the result leaves out
The labels A and B can represent homes, cities or scenarios. Equal scope matters more than a city label. Example totals are fictional.
