About this calculator

Volunteer time is a real contribution and belongs in your impact reporting — but managing volunteers costs money too. This values the hours at the rate you choose and nets out coordination, training, and screening costs.

FormulaValue = hours × hourly value; net = value − (coordinator time + training + screening).

FAQ

Can we record volunteer time as revenue?

Only in narrow cases. GAAP recognizes contributed services when they create or enhance a non-financial asset, or require specialized skills the organization would otherwise purchase. General volunteer help stays out of the financial statements — but still belongs in your annual report.

Which hourly rate should I use?

The Independent Sector national estimate for general service, or a market rate for skilled work like pro bono legal or accounting hours, which are worth several times the general figure.

Accuracy and limitations

Results are estimates before tax, fees, and inflation unless an input explicitly covers them.
Rates are treated as fixed for the whole period — variable-rate products will drift from this projection.
This is educational maths, not financial advice. Check anything contractual with the lender or your accountant.
