Loan Calculator
Calculator Uee
Use this loan calculator to easily figure out your monthly payment, interest rate, number of months, or principal amount for a loan. Discover your optimal payment by adjusting the loan amount, interest rate, and term to see how it impacts the payment amount. This tool empowers you to find the ideal combination that suits your financial preferences. Experiment with different scenarios to understand how changes in loan details influence your monthly commitment, allowing you to make informed decisions about your borrowing needs.
Loan Calculator Variables
Loan Amount: The initial amount borrowed for a new loan or the remaining principal on an existing loan.
Interest Rate: The annual nominal interest rate, also known as the stated rate, applicable to the loan.
Number of Months: The total count of payments needed to fully repay the loan.
Monthly Payment: The specific amount due for the loan at each monthly payment deadline.
Compounding: This calculator operates on the assumption that interest compounds monthly in sync with payments. For more compounding options, explore our Advanced Loan Calculator.
Certainly! Let’s provide an explanation of how each loan calculation is performed using formulas and examples:
1. Find The Monthly Payment:
Formula: M=(1+r)n−1P⋅r⋅(1+r)n
- M: Monthly Payment
- P: Loan Amount
- r: Monthly Interest Rate (Annual Interest Rate / 12 / 100)
- n: Number of Monthly Payments
Example: Suppose you take out a loan of $10,000 with an annual interest rate of 5% for 3 years (36 months). The monthly payment would be calculated as follows:
r=12×1005=0.00417
n=36
M=(1+0.00417)36−110000×0.00417×(1+0.00417)36
2. Find The Loan Amount:
Formula: P=rM⋅(1−(1+r)−n)
- P: Loan Amount
- M: Monthly Payment
- r: Monthly Interest Rate (Annual Interest Rate / 12 / 100)
- n: Number of Monthly Payments
Example: If you want to borrow $200 per month for 5 years (60 months) with an annual interest rate of 6%, the loan amount would be calculated as:
r=12×1006=0.005
n=60
P=0.005200×(1−(1+0.005)−60)
3. Find The Number of Months:
Formula: n=−log(1+r)log(1−MP⋅r)
- n: Number of Monthly Payments
- P: Loan Amount
- r: Monthly Interest Rate (Annual Interest Rate / 12 / 100)
- M: Monthly Payment
Example: If you have a loan amount of $8,000 with a monthly payment of $150 and an annual interest rate of 4%, the number of months would be calculated as:
r=12×1004=0.00333
n=−log(1+0.00333)log(1−1508000×0.00333)
4. Find The Interest Rate:
Formula: r=PM1/n−1
- r: Monthly Interest Rate (Annual Interest Rate / 12 / 100)
- M: Monthly Payment
- P: Loan Amount
- n: Number of Monthly Payments
Example: If you have a loan amount of $12,000, a monthly payment of $250, and the loan term is 4 years (48 months), the annual interest rate would be calculated as:
r=(12000250)1/48−1
These formulas and examples illustrate how each loan calculation is performed. Users can use these formulas to understand the relationship between loan amount, monthly payment, interest rate, and loan term.
