Simple Interest Calculator (Notebook Template)
Compute simple interest (I = P·r·t) and total amount. Good for quick estimates and verification baselines.
What this template does
This is a ready-to-run GetCalcMaster Notebook starter. Open it into Notebook, run once with defaults, then tweak inputs and keep your assumptions next to the math.
How to use it (recommended)
- Open in Notebook.
- Set P (principal), r (annual rate), and t (years).
- Compute interest I and total A.
- Use this as a baseline to compare against compound interest products.
- Save a snapshot with assumptions (rate, time basis, fees).
Tip: When a result matters, verify it twice: a unit check + a second method (graph/estimate).

TEXT
# Simple Interest Calculator (Notebook) Formula: - **I = P × r × t** - **A = P + I** Where **r** is a decimal annual rate and **t** is time in years.
MATH
P = 2500
MATH
r = 0.08 # annual rate
MATH
t = 1.5 # years
MATH
I = P * r * t
MATH
A = P + I
