How to use this calculator
Open the short walkthrough for choosing and checking inputs.
The calculator converts combined megabits per second into decimal gigabytes across the daily recording window, multiplies by retention days, adds saved-event reserve, and rounds up to a common card-capacity tier.

Calculation details
Formula and methodology
See the exact math used to produce the result.
The calculator combines the inputs above into a practical planning estimate.
Before acting
Assumptions to check
Review the real-world details that can change the estimate.
The key inputs are Combined video bitrate, Simultaneous camera channels, Recording per day, Loop-recording window, Saved-event reserve. Confirm combined bitrate in the selected recording mode, supported card capacity, speed class, high-endurance use, file-system format, parking-mode behavior, loop overwrite settings, and saved-event reserve before buying media.

When to round up
Choose a high-endurance card at or above the result, then confirm the dash cam's supported capacity, required speed class, file-system format, front-and-rear bitrate, parking mode, overwrite behavior, and manufacturer card guidance.
When to use this calculator
- Planning print dimensions, recording storage, timelapse capture, or upload time
- Comparing media and backup capacity before a shoot or installation
- Estimating delivery windows from measured file sizes and upload speed
Tips for better estimates
- Use original pixel dimensions, the selected camera mode, and the bitrate reported for that mode.
- Compare estimates with formatted card or drive capacity and leave room for variable bitrate, proxies, exports, and duplicate backups.
- Use a recent upload-speed test from the actual network and allow for Wi-Fi variation, retries, and cloud processing.
How this estimate was built
This page converts combined recording bitrate and active hours to decimal gigabytes, multiplies by the requested loop-recording window, adds saved-event reserve, and rounds up through common memory-card capacity tiers.
Worked example
Example inputs: Combined video bitrate: 12 Mbps; Simultaneous camera channels: 1; Recording per day: 8 hours; Loop-recording window: 3 days; Saved-event reserve: 15 %. With those values, the calculator returns 256 GB card recommended dash-cam storage. Use at least 256 GB card, subject to the dash cam's supported card capacity and recording mode.
Example scenarios
- Use 256 GB card recommended dash-cam storage as the first workflow estimate, then compare it with the original file or the exact recording-mode specifications.
- Leave capacity for formatted-media loss, variable bitrate, proxies, exports, setup frames, retries, and a separate backup copy.
- Rerun transfer estimates with measured upload speed from the network and time of day that will actually be used.

FAQs
Dash Cam Storage Calculator questions
Can I use this as an exact photo or video workflow result?
No. Use it as a planning estimate, then confirm original file dimensions, the selected recording mode, formatted media capacity, measured upload speed, and workflow overhead.
Should I add storage or transfer headroom?
Yes. Leave room for variable bitrate, RAW files, proxies, thumbnails, exports, retries, duplicate backups, and cloud-side processing.
What should I check before buying storage media?
Check supported capacity, sustained write speed, endurance rating, file-system format, formatted capacity, and the camera or recorder manufacturer's requirements.
Does upload time use download speed?
No. Use measured upload speed from the actual connection, then allow for shared bandwidth, Wi-Fi variation, protocol overhead, retries, and many-small-file slowdown.
Is the dash cam storage calculator exact?
No. It is a media-planning estimate. Cropping, compression, variable bitrate, storage overhead, editing files, connection speed, and service behavior can change the result.
What inputs matter most?
Combined recording bitrate, camera channels, daily recording hours, retention window, and reserve space determine the card tier.

Common planning mistakes
Using resolution labels instead of actual pixels or bitrate, confusing upload speed with download speed, ignoring formatted media capacity, and leaving no room for variable bitrate, retries, exports, or backup copies.
