  "summary": "See how far actuals have drifted from budget, by dollar and percent.",
  "description": "Board finance committees review budget-to-actual reports every meeting, but raw dollar variances without a percentage and a materiality threshold make it hard to tell a $3,000 miss on a small program line from a $3,000 miss on a major revenue category that actually matters. This calculator takes a budgeted amount and actual amount for revenue or expense lines, computes the dollar variance and percentage variance, and flags whether it crosses a materiality threshold you set, typically 10% or a fixed dollar amount, whichever is more meaningful for a given line, since a 10% variance on a $2,000 line item usually isn't worth board discussion time while a 5% variance on a $500,000 revenue line absolutely is.",
  "formula": "Variance $ = actual − budget; variance % = variance $ ÷ budget × 100; flagged if |variance %| > threshold.",

    {
      "q": "What materiality threshold should a board use?",
      "a": "Many finance committees use a dual test: flag anything over 10% variance AND anything over a fixed dollar threshold (often $5,000-25,000 depending on budget size), whichever triggers first, so both small-dollar-but-high-percentage misses and large-dollar-but-low-percentage misses both get surfaced."
    },
    {
      "q": "Is a favorable revenue variance always good news?",
      "a": "Not automatically. Revenue coming in over budget from a one-time bequest is good news but not repeatable, and shouldn't be used to justify ongoing spending increases. Distinguish one-time favorable variances from sustainable, structural ones before changing spending plans."
    },
    {
      "q": "How often should variance reports go to the board?",
      "a": "Quarterly at minimum, monthly for organizations with tight cash positions or heavy reliance on unpredictable revenue like events and major gifts. Waiting until year-end to discover a 20% revenue shortfall eliminates any chance to course-correct mid-year."
    },
    {
      "q": "What's the difference between a variance and a forecast reforecast?",
      "a": "Variance analysis looks backward at what already happened versus what was planned. A reforecast looks forward, using variance trends to update your expectation for the rest of the year, for example if grant revenue is consistently 15% behind budget through Q2, your reforecast should reflect that trend continuing, not assume a sudden catch-up."
