How the EIDL Loan Calculator Works (Formula Explained)
This calculator uses a standard loan amortization formula, which is widely used in banking and financial institutions.
1. Monthly Interest Rate Conversion
The annual interest rate is converted into monthly form:
Monthly Interest Rate = Annual Rate ÷ 100 ÷ 12
2. Loan Term in Months
Loan duration is converted into months:
Total Months = Years × 12
3. Monthly Payment Formula (Amortization)
If interest rate is greater than zero:
Monthly Payment =
P × r × (1 + r)^n / [(1 + r)^n – 1]
Where:
- P = Loan amount
- r = Monthly interest rate
- n = Total number of months
If interest is 0%:
Monthly Payment = Loan Amount ÷ Number of Months
4. Extra Payment Impact
When you add extra monthly payments:
- More principal is paid each month
- Loan balance reduces faster
- Interest decreases over time
- Loan is paid off earlier
5. Total Interest Calculation
Total Interest = Total Paid – Loan Amount
6. Interest Savings
Interest Saved = Base Interest – New Interest (with extra payments)
This is one of the most important features because it shows how much money you save by paying more each month.
Example Calculation
Let’s understand with a real-world example:
Loan Details:
- Loan Amount: $50,000
- Interest Rate: 3.75%
- Loan Term: 10 years
- Extra Payment: $100 per month
Step-by-Step Outcome:
- Monthly Payment (Base): ≈ $500.96
- New Total Payment (with extra): Lower overall due to early payoff
- Payoff Time: Reduced from 120 months to ~100 months
- Interest Saved: Significant reduction over loan term
What This Means
By adding just $100 extra monthly:
- You shorten loan duration
- You reduce total interest significantly
- You become debt-free earlier
This shows how small financial changes can create long-term savings.
