Accelerated Stability Study Calculator | Accelerated Aging Testing & Shelf Life
Run accelerated aging testing using the accelerated aging formula (Q10) or the Arrhenius equation accelerated aging to estimate accelerated shelf life.
Forward: Real-Time → Accelerated
Reverse: Accelerated → Real-Time
How It Works
This accelerated stability study calculator supports two approaches: the Q10 method and the Arrhenius equation accelerated aging. Use Q10 for quick plans, Arrhenius for a physics-based estimate.
Q10 Method: AAF = Q10^((T_AA - T_RT) / 10) → Accelerated Time = Real-Time ÷ AAF
Arrhenius Method: AAF = exp[(Ea/R)·(1/T_RT(K) - 1/T_AA(K))] (temps in Kelvin)
Sample conversions
| Method | T_RT (°C) | T_AA (°C) | Q10 / Ea | Real-Time | AAF | Accelerated Time |

FAQ: Accelerated Aging Testing
What is accelerated aging testing?
It’s a way to speed up stability studies by raising temperature (and sometimes humidity) so you can estimate shelf life faster with an aging test calculator.
When should I use the accelerated aging formula vs. Arrhenius?
Use the accelerated aging formula (Q10) for quick planning. Choose the Arrhenius equation accelerated aging model when you have activation energy data for your material and want a tighter estimate.
What Q10 value should I start with?
Q10 = 2 is a common starting point in packaging and medical device work. Some products justify Q10 = 3. Document your assumption.
What about humidity and other factors?
Temperature is the main driver in these models. If humidity or UV is known to matter for your product, include them in your study design alongside this accelerated shelf life calculator.
Can I switch units?
Yes. The calculator treats time units consistently and returns results in the unit you selected.
