The calculator will display the amount of extra money you can apply towards your principal each month, the total interest saved, and the new loan balance after the specified period.

Formula Explained

The formula used in this calculator is based on the amortization of a loan. The amount of extra money you can apply towards your principal each month is calculated using the following steps:

Step 1: Calculate Monthly Interest

First, calculate the monthly interest on your loan balance:

Monthly Interest = Loan Balance × (Interest Rate / 12)

Step 2: Determine Principal Portion

Next, determine the portion of your monthly payment that goes towards the principal:

Principal Portion = Monthly Payment - Monthly Interest

Step 3: Calculate Extra Principal

Finally, calculate the extra money you can apply towards your principal each month:

Extra Principal = Total Extra Payment - (Monthly Payment - Principal Portion)

This formula helps you understand how much of your extra payments will go towards reducing your loan balance and how much will go towards interest.

Worked Example

Let's look at an example to see how this calculator works. Suppose you have a loan with the following details:

Current Loan Balance: $20,000
Monthly Payment: $300
Interest Rate: 5% (0.05)
Number of Months: 12

Using the calculator, you can determine how much extra money you can apply towards your principal each month.

Example Calculation

For the first month:

Monthly Interest = $20,000 × (0.05 / 12) = $83.33
Principal Portion = $300 - $83.33 = $216.67
Extra Principal = $0 (since no extra payment is applied yet)

After 12 months, with no extra payments, your loan balance would be approximately $19,500.

If you apply an extra $100 each month, the calculator will show you how much of that extra payment goes towards your principal and how much reduces your loan balance.

Strategies for Applying Extra Money

Applying extra money towards your loan principal can help you pay off your debt faster and save on interest charges. Here are some strategies to consider:

Snowball Method: Apply extra payments to the smallest loan balances first to build momentum and stay motivated.
Debt Avalanche Method: Apply extra payments to the loan with the highest interest rate first to minimize overall interest paid.
Biweekly Payments: Make payments every two weeks instead of monthly to reduce the principal balance faster.
Refinance or Consolidate: Consider refinancing or consolidating your loans to get a lower interest rate and save on interest charges.

By using these strategies, you can maximize the impact of your extra payments and pay off your loans faster.
