40-Year Timeline
Project every replacement event over 40 years with compounding inflation and per-year cost overrides.
How the 40-Year Timeline Works
The engine projects every component replacement across a 40-year horizon. Costs grow with your chosen inflation rate, and you can override any year with a known expense.
- 40-year projection with compounding inflation (1–40 years, customizable)
- Per-year cost overrides for planned renovations
- Replacement events stacked by year for easy scanning
- Stacked area chart shows which components drive cost spikes
Cumulative Cost Chart and Most-Expensive-Year Detection
Beyond the year-by-year breakdown, a cumulative cost chart shows your running 40-year total, and the engine automatically flags the single most expensive year and the components driving it.
- Cumulative line chart: total CapEx burden across the projection horizon
- Most-expensive-year banner: the year, the dollar amount, and the components
- Cash-flow crunch year identification — know when multiple replacements collide
- Per-year breakdown table paginated by 10-year periods
Why This Matters
A roof replacement in year 8 costs very differently than in year 28 once inflation compounds. The timeline shows you the real future cost of every event, not just today's estimate — and warns you when expenses overlap.
- See the true inflation-adjusted cost of future replacements
- Identify years with multiple overlapping expenses
- Plan major renovations around high-expense years
