Maintenance Budget Forecast & Variance Calculator

Maintenance Budget Forecast & Variance Calculator takes prior-year actuals by cost line, your own escalation %, planned changes, the month-by-month shape of your year, and actuals as they land and returns a month-by-month maintenance budget, the variance against it to date, and a re-forecast for the rest of the year. Budget = prior-year actual × (1 + your escalation %) + your planned change. The annual budget is phased across twelve months by shares you set, which must total 100%. Variance = actual − budget, per month and cumulative. The re-forecast is actual-to-date plus the remaining budget × a run-rate factor you set — 1.0 means the rest of the year runs to plan, and the workbook shows your actual run rate beside it. Nothing is pre-filled with an outside figure — no inflation assumption, no escalation default, no seasonal profile, no spend benchmark. Every value on every sheet is one you entered or one computed from what you entered, against the As-of date you set on 1. Setup, never today's date.
