Calculateur de Token Expiry Buffer
Calculate refresh timing from token lifetime and safety buffer.
Formula and method
This calculator computes Refresh after, Refresh after directly in your browser without sending data to an external server.
Mathematical formula
- Refresh after:
Math.max(lifetime-buffer,0) - Refresh after:
Math.max(lifetime-buffer,0) × 60
Variables and parameters
- Token lifetime (lifetime): default value 60 minutes.
- Safety buffer (buffer): default value 5 minutes.
Some formulas are undefined for certain input combinations (such as division by zero or logarithms of non-positive numbers). In those cases the live tool displays an alert instead of NaN.
