Formula Used in Certificate Rate Calculator
This calculator uses the Simple Interest Formula to estimate returns.
Simple Interest Formula
I=100P×R×T
Where:
- P = Principal (Initial Amount)
- R = Interest Rate (%)
- T = Time (Years)
- I = Interest earned
Final Value Formula
A=P+I
Where:
- A = Final Amount
- P = Principal
- I = Interest
Combined Formula
A=P+100P×R×T
This formula helps calculate the total value of investment after interest is added.
Example Calculation
Let’s understand with a real example:
- Principal (P) = $2000
- Rate (R) = 6%
- Time (T) = 4 years
Step 1: Calculate Interest
I=1002000×6×4
Step 2: Final Value
A=2000+480
Result:
- Interest = $480
- Final Amount = $2480
