Key benefits include:

How to Use the 120,000 Mortgage Calculator
Using this tool is simple and takes only a few seconds.
Step 1: Loan Amount (Fixed)
The loan amount is already set to:
$120,000
This represents the standard mortgage principal used in the calculation.
Step 2: Enter Interest Rate
Input your annual interest rate in percentage.
Example:
- 4%
- 5.5%
- 7%
This determines how much extra you pay on top of the borrowed amount.
Step 3: Enter Loan Term
Enter how long you plan to repay the loan in years.
Common options include:
- 10 years
- 15 years
- 20 years
- 30 years
Longer terms reduce monthly payments but increase total interest.
Step 4: Enter Extra Monthly Payment (Optional)
This is an additional amount you can pay every month to reduce your loan faster.
Example:
- $50
- $100
- $300
This field is optional but powerful for saving interest.
Step 5: Click Calculate
The calculator instantly displays:
- Monthly payment
- Total repayment amount
- Total interest cost
- Payoff time in months
- Time saved with extra payments
Mortgage Calculation Formula Explained
The calculator uses a standard financial formula known as the amortization formula.
Monthly Payment Formula
M=1−(1+r)−nP×r
Where:
- M = Monthly mortgage payment
- P = Loan amount ($120,000)
- r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
- n = Total number of months (years × 12)
Total Payment Formula
Total Payment=M×n
Total Interest Formula
Total Interest=Total Payment−P
Early Payoff Simulation
When extra payments are added, the calculator simulates:
- Monthly interest on remaining balance
- Principal reduction
- Faster payoff cycle
- Total months required to clear loan
This allows accurate estimation of time saved and interest saved.
