# What do volunteer no-shows cost your organization?

The calculator above turns four numbers you already know — how many shifts you run, how many volunteers each needs, how often they no-show, and how long a shift is — into a defensible yearly dollar figure. Here is exactly how it gets there, and where the honesty lines are.

[[TOC]]

## How is the no-show cost calculated?

The math is deliberately simple, so you can check it and cite it:

- **Missed shifts per year** = shifts per week × 52 × volunteers per shift × no-show rate.
- **Volunteer hours lost** = missed shifts × the length of a shift.
- **Dollars lost** = hours lost × the value of a volunteer hour.

With the defaults — 5 shifts a week, 4 volunteers each, a 15% no-show rate, 3-hour shifts — that is 156 missed shifts, 468 volunteer hours, and about **$16,914 a year** at the national rate (about $1,409 a month). Nothing is hidden: the formula is right here, dollars are rounded to the nearest whole dollar, and the result updates live as you change the inputs.

## Where does the $36.14 an hour come from?

The value of a volunteer hour is **$36.14** for 2025, from [Independent Sector's Value of Volunteer Time research](https://independentsector.org/research/value-of-volunteer-time/) — the same figure nonprofits use in annual reports and grant applications. Independent Sector recalculates it every April; when they do, we update this calculator, because the freshness is part of why the number is worth citing. They also publish state-by-state values.

<!-- VERIFY: state-by-state hourly values + Independent Sector's reuse license for a derived tool. Until that is cleared, the state selector falls back to the national $36.14 figure and shows the "national value" note (see spec §6 and STATE_HOURLY in src/domain/noShowCalc.ts). -->

## Do text reminders actually cut no-shows?

Reminders have been studied most rigorously in healthcare, not in volunteering. In one randomized trial at a pediatric clinic, text-message reminders cut appointment no-shows from about **38% to 24%** — roughly a 38% relative drop ([PMC5227159](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5227159/)). That is a medical clinic, not a volunteer program, and it is a single study — so treat it as directional, not a promise. We deliberately do **not** convert it into a dollar "savings" figure on this page, because no volunteer-specific research exists to justify one.

<!-- VERIFY: PMC5227159 is ONE pediatric-clinic RCT (n=170): 38.1% control vs 23.5% intervention (~38% relative / 14.6pp absolute reduction). Do NOT restate as a "26–38%" range or as "trials" (plural), and do NOT dollarize a recoverable band from it (per review). -->

## What does this number really tell you?

**There is no published, sector-wide volunteer no-show rate — anyone who quotes one is guessing.** That is why this calculator asks for your estimate instead of supplying one. The dollar figure is only as good as the no-show rate you enter, so use what you have actually seen over the last few months, and treat the result as a planning estimate for a board deck or a grant narrative — not an audited cost.

The optional coordinator-scramble line values your own phone-around time at the same volunteer-hour rate. That is a rough proxy: a paid coordinator's time may be worth more or less than a volunteer hour. It is there to make the hidden cost visible, not to be precise to the dollar.

## FAQ

### What is a volunteer hour worth?

Independent Sector values a US volunteer hour at $36.14 for 2025, and updates the figure every April. They also publish state-by-state values. This calculator uses the national figure.

### What is a normal volunteer no-show rate?

There is no credible, published sector-wide volunteer no-show rate — anyone who quotes one is guessing. That is why this calculator asks for your own estimate. Use what you have actually seen over the last few months.

### Do text reminders actually reduce no-shows?

In healthcare, where reminders have been studied most, one randomized trial in a pediatric clinic found text reminders cut appointment no-shows from about 38% to 24%. Volunteer programs have not been studied with the same rigor, so treat that as a directional analogy, not a promise.

### Is the calculator free to use?

Yes — it is free, needs no email, and is free to cite or link. Put the number in your board deck or newsletter.
