Editable example values

Deleted files may remain in trash or version history and may not free space immediately. Use the provider's observed trend.

How far baseline usage may move up or down. It provides the basis for the result range.

Check the inputs and calculate

Changing an input immediately clears the previous result so conditions cannot be mixed up.

Formula and assumptions

Days and date are an upgrade-review point if recent net growth continues. At zero or negative growth, the result says storage is not decreasing under current inputs.

Convert daily, weekly, or monthly growth to a common daily net rate and divide remaining capacity by that rate. Recalculate with growth 20% higher or lower for scenarios.

Why the result can vary

Large uploads, backup policy, retention, deduplication, compression, deletion, and trash retention can abruptly change net growth.

Example

Plan an upgrade for photo backups

Inputs: 300GB remaining, 30GB net growth per month

Outcome: The baseline is about 10 months; 20% faster growth shortens it to roughly 8.3 months.

Cautions

  • Check how your service counts file versions, history, and trash.
  • Leave operational headroom and enough time for any data migration before the projected date.

How many years of rated SSD TBW remain?

Subtract recorded writes from manufacturer-rated TBW and use average daily writes to estimate when that rating is reached.

How many hours can I stream with my mobile data?

Use remaining data and an observed hourly rate to estimate continuous streaming and days at several daily viewing patterns.

How many times can a power bank charge my phone?

Estimate how many times a 10,000mAh or 20,000mAh power bank can charge an iPhone or Galaxy after voltage conversion, cable, wireless, and battery-condition losses.

Frequently asked questions

Should I enter total uploads or net growth?

Net growth after deletions and cleanup better describes how quickly available capacity is disappearing.

Is every month treated as exactly 30 days?

Periods are converted to a common time basis. Treat the calendar date as an estimate because month lengths vary with the start date.

What happens if growth is zero or negative?

The result says storage is not shrinking under current inputs instead of producing infinity. Enter future upload plans as a separate scenario.
