📂 Depreciation Files

Each depreciation file is a separate Google Sheet. Tap ⋮ → New depreciation file to create one, or Add shared file to link a file someone shared with you.

➕ Adding a Depreciation Item

Tap + Add item. Fill in:

• Name — description of the asset being depreciated
• Start date — when depreciation begins
• Start value — the depreciable value (purchase cost)
• Type — e.g. Plant & Equipment, Capital Works
• Method — Diminishing Value or Prime Cost
• Initial rate — annual depreciation rate (e.g. 0.20 = 20%)
• Linked expense — optional link to the purchase expense
• Category / Tags — optional classification and labels

📐 Calculation Methods

Diminishing Value (DV) — applies the rate to the current book value each year. The depreciation amount decreases over time as the book value falls.

Prime Cost (PC) — applies the rate to the original cost each year. The depreciation amount stays constant, reaching zero at end of useful life.

📈 Changing the Rate

Open an item and tap Add rate change in the Rates section. Enter the date the new rate takes effect. The schedule will recalculate from that point using the new rate.

✂️ Write-offs

Record a write-off by opening the item and tapping Add write-off. Enter the date and the amount written off. Write-offs reduce the book value immediately and are reflected in the schedule from that date.

📅 Depreciation Schedule

The detail screen shows a year-by-year schedule with:

• Opening value — book value at start of year
• Rate — rate applied that year
• Depreciation — amount deducted that year
• Write-offs — any write-offs in that year
• Closing value — book value at end of year

🗑️ Disposal

Set a disposal date on an item to mark it as disposed. Disposed items appear separately in the list with their final book value at the time of disposal.

🤝 Shared Files

Tap ⋮ → Add shared file and paste a Google Sheets URL to link a depreciation file someone else shared with you. Read-only files are labelled.
