Pick your home systems. The planner adds only the rows we can defend: national permit-cost median divided by a cited InterNACHI planning lifespan. Water heaters, panels, and sewer lines stay quote-only because their trade buckets are too broad.
Your selections stay on this device. The total sums only rows with a permit cost and cited lifespan.

InterNACHI Standard Estimated Life Expectancy Chart for HomesThe permit index has a plumber median, but it pools water heaters, drains, repipes, sewer work, and other jobs. We do not publish that pooled number as this specific replacement cost.
Get a quoteAppliances are intentionally excluded from this planner because ordinary appliance replacements do not have a permit-cost source.
The numerator is the Real Cost Index permit median. The denominator is the cited InterNACHI lifespan shown on the row. If either half is missing, the row cannot contribute dollars to the total. Permit declared values can run below a final invoice, so compare the IQR and get quotes before committing cash.
No. Every row is labeled estimate, not a quote. Dollar rows use national Real Cost Index permit medians and InterNACHI lifespans; final contractor invoices can differ from declared permit values.
Their lifespans are cited, but the permit index buckets for plumbers and electricians pool many unrelated jobs. We do not publish a pooled trade median as if it were a job-specific replacement price.
No. The 1%-4% home-value rule is shown only as a separately sourced sidebar. The reserve total sums only selected systems with both a real permit-cost benchmark and a cited lifespan.
This planner is scoped to national benchmarks from the Real Cost Index. Each dollar row displays the median, interquartile range, sample size, and national scope with a link to the cost index.
