Maintenance Reserve Calculator (Pro)

Plan realistic maintenance and capital reserves based on property-specific components and timelines.

Tool Overview

The Maintenance Reserve Calculator helps you estimate how much capital should be set aside to maintain a property over time, accounting for both routine repairs and major capital expenditures.

Unlike simplified “rule of thumb” approaches, this tool is designed to reflect the actual components of a property, their expected lifespans, and the timing of future replacements. It provides a structured way to plan for inevitable maintenance costs rather than reacting to them as surprises.

This tool supports disciplined capital planning and helps investors understand the true cost of ownership beyond operating expenses.

Analysis Depth

This tool provides forward-looking maintenance and capital planning, not cash flow or return forecasting.

It separates maintenance reserves from operating expenses and focuses on the timing and scale of future repair and replacement needs. The Maintenance Reserve Calculator does not estimate appreciation, resale value, or investment returns.

Its purpose is to help investors evaluate whether projected cash flow is sustainable after accounting for realistic maintenance reserves.

Calculated Results & Performance Breakdown

After calculation, the tool provides a structured reserve summary, including:

  • Annual Capital Reserve Requirement
    The annual amount required to fund long-term component replacements.

  • Monthly Capital Reserve Requirement
    Capital reserves expressed on a monthly basis for budgeting purposes.

  • Routine Maintenance Reserve
    Allowance for ongoing minor repairs and maintenance.

  • Total Monthly Maintenance Reserve
    The combined monthly amount recommended to be set aside for property upkeep.

Results are presented to highlight both near-term maintenance risk and long-term capital planning requirements.
