The direct answer
A short-term-rental replacement reserve is a planning allowance for future furniture, appliance, linen, electronics and other capital replacements that are not captured by ordinary cleaning or minor maintenance. It is not a standardized accounting rule, but including a reserve can make long-run cash-flow scenarios more realistic.
Identify items with replacement cycles
Beds, sofas, televisions, appliances, outdoor furniture, linens and smart-home equipment wear at different rates. A useful reserve schedule lists expected replacement cost and an assumed useful planning period for each category.

Keep reserves separate from routine expenses
Cleaning, small repairs and consumables are operating expenses, while a replacement reserve is a planning mechanism for larger periodic outlays. Avoid counting the same cost in both categories.
Stress high-usage scenarios
Properties with high occupancy, larger groups, pets or harsh climate exposure can experience faster wear. Run a base and downside replacement schedule instead of assuming every asset lasts to an optimistic maximum.
Worked example
If a furnishing package expected to cost $24,000 to replace is modeled over six years, a simple planning reserve is $4,000 per year before inflation and uneven item timing. Actual replacements will occur irregularly rather than evenly.

Common mistakes and limitations
Do not present a reserve percentage as a universal industry standard. Replacement needs depend on the property, furnishing quality and use pattern.
Uses user-entered assumptions and does not access Airbnb/AirDNA or guarantee local STR legality, demand or pricing.
Frequently asked questions
Is a replacement reserve the same as depreciation?
No. A reserve is a cash-planning assumption, while tax depreciation follows separate tax rules.
Should a reserve be deducted from modeled cash flow?
For conservative underwriting, many investors model it as a cash-flow allowance even though the actual spending occurs unevenly.
