Property ownership
Property repair replacement reserve
Fund a user-entered list of replacement amounts and dates.
Your inputs
Complete the fields for your selected method. Zero means intentionally zero, not unknown. Currency selection labels amounts; it does not convert exchange rates.
How this calculation works
sum(required annual deposits by asset and remaining life).
Enter already-estimated replacement amounts; no construction takeoff. Deposits are earmarked savings, not additional lifecycle expenses.
What information do I need?
Use records for the same job, equipment or accounting period. Only the fields for your selected entry method are required. An unknown amount is not zero.
Input definitions and where to find them
- Replacement reserve items: One row per distinct replacement reserve items, on the stated row and period basis. Do not enter both components and their total.
- Future replacement cash amount (selected currency): Matching invoice, quote, statement, bookkeeping record or explicit budget amount for future replacement cash amount. Use the stated period and exclude amounts already counted in another field. Zero means intentionally excluded/not incurred, not unknown.
- Funds already earmarked (selected currency): Funds earmarked for THIS asset; do not duplicate total reserve funds across rows.
- Years until replacement (years): Remaining years until the planned replacement date, not asset age.
Use the Where to find this value controls beside the inputs for available work-it-out helpers. Estimates remain your assumptions; a helper does not verify the source figures.
Worked example
Example amounts use US dollars (USD).
Example answer: Required annual reserve deposits is $4,000.00 for the illustrative inputs below.
Example inputs
- Replacement reserve items
- Future replacement cash amount: $10,000.00
- Funds already earmarked: $2,000.00
- Years until replacement: 4.00 years
- Future replacement cash amount: $6,000.00
- Funds already earmarked: $0.00
- Years until replacement: 3.00 years
- Required annual reserve deposits
- $4,000.00
- No interest earned; equal annual contributions. Future amounts already include any assumed inflation. Overfunding one asset does not offset another earmarked asset.
These illustrative values are not recommended rates or industry averages. Replace every example input with your own figures.
Use the result well
Fund a user-entered list of replacement amounts and dates.
Keep inputs on the same scope and time basis. Calculations retain precision internally; displayed values generally round to two decimal places, with extra precision for very small values and whole-unit rounding where required. Economic comparisons describe your supplied assumptions and do not guarantee future results.
