A buffer of recorded, unpublished episodes is what keeps a show consistent when a guest cancels, someone gets sick or the host takes a week off. The problem is that most hosts only notice the buffer when it is gone. The math behind it is simple, but it is easy to lose track of when recordings and releases run on different rhythms.

This calculator takes the episodes you already have in the can, your publishing cadence and your recording pace, and turns them into weeks of runway. It also spreads your weeks off across the year to get a realistic weekly recording rate, then tells you whether the buffer is growing toward your target or shrinking toward zero, and roughly how long that will take.

How to use this tool

Count the episodes you have recorded that have not been released yet and enter them along with your weekly publishing cadence.
Enter how many episodes you record in a normal month and how many weeks per year you take off from recording.
Set the buffer you want to hold, then read the runway, the net weekly change and the verdict on whether you are gaining or losing ground.

What the math assumes

Runway is episodes banked divided by episodes published per week; publishing is assumed to continue at the same pace with no breaks.
The weekly recording rate spreads your monthly recordings over the year, minus your weeks off, so it is an average and not a week by week schedule.
Every recording is treated as one publishable episode; recordings that get scrapped or split into several parts are not modeled.
The time to reach target assumes the current net rate holds steady and rounds up to whole weeks.
Time to run dry is measured from now at the current net rate; it does not account for a recording push you might make in the meantime.

Frequently asked questions

What is a reasonable buffer for an interview podcast?

It depends on how often guests cancel on you and how long editing takes. Many hosts aim for at least a few weeks so a single dropout never forces a missed release; set the target to what would let you sleep at night.

Why is my net change negative even though I record four times a month?

Four recordings per month is a little under one per week once you spread it over 52 weeks, and weeks off pull the average down further. If you publish weekly, the buffer slowly drains unless you record more than you release.

Should episodes still in editing count as banked?

Yes, if they have a release slot ahead of them and you are confident they will ship. If your editing backlog is unreliable, count only the episodes that are finished and scheduled.
