Start with a few details about your home, then get a planning briefing with ranges, confidence, next actions, and what would improve the estimate.

Whole home

Home Maintenance Budget Calculator

Use this calculator to estimate a practical annual and monthly maintenance budget from home value, age, size, condition, and climate wear. It is a planning range, not a guarantee.

Lifespan
Not system-specific; the estimate combines home age, condition, recurring maintenance, and major-system planning context.
Replacement range
Connects larger replacement ranges from roof, HVAC, water heater, electrical, and window planning.

Home Reserve Fund Calculator

Use this calculator to connect home reserve savings to likely repair pressure, known upcoming costs, and a practical monthly savings target.

Lifespan
Reserve planning follows each major system, not a single lifespan.
Replacement range
Estimates long-term reserve targets for roof, HVAC, water heater, windows, electrical, and other major systems.

Water heater

Water Heater Replacement Calculator

Use this calculator to estimate whether a water heater is in a monitor, plan, or quote-now window based on age, type, symptoms, and urgency.

$9,000-$35,000+ for many full replacements.

HVAC

HVAC Replacement Calculator

Use this calculator to organize HVAC replacement planning around age, home size, comfort symptoms, climate demand, and monthly reserve needs.
