📊 Real-world Examples of Decrease Over Time
Depreciation
Assets like vehicles and equipment lose value over time, often following predictable patterns.
Radioactive Decay
Substances decay exponentially based on their half-life, used in carbon dating and medicine.
Inventory Depletion
Products in inventory decrease as they're sold, which can be modeled with different patterns.
Drug Metabolism
Medications in the body decrease over time as they're metabolized and eliminated.
🧮 Decrease Formulas Explained
Formula: Vt = V0 × (1 - r)t
Where:
- Vt = Value at time t
- V0 = Initial value
- r = Percentage decrease per period (as decimal)
- t = Number of periods
This creates a curve where the absolute decrease gets smaller each period as the base value decreases.
Formula: Vt = V0 - (d × t)
Where:
- Vt = Value at time t
- V0 = Initial value
- d = Fixed decrease amount per period
- t = Number of periods
This creates a straight line decrease where the same amount is subtracted each period.
Formula: Vt = V0 × e-λt
Where:
- Vt = Value at time t
- V0 = Initial value
- λ (lambda) = Decay rate
- t = Number of periods
- e = Euler's number (~2.71828)
This models natural decay processes where the rate of decrease is proportional to the current value.
Note: This calculator provides estimates based on mathematical models. Actual decrease patterns may vary in real-world scenarios due to external factors not accounted for in these calculations.
