The loan calculator is one of our most popular financial calculators. It can solve for one of four unknown values, or you can enter values for loan amount, term, interest rate and payment and it will create a schedule using your values. More below...»
About dates - if you want to create a schedule that accurately reflects a loan's origination date (the day the money is borrowed) and the first payment date followed by regularly scheduled payments, then use our amortization schedule.
Don't over pay, don't under collect. If you need to track payments on the exact date they are paid (or missed) for whatever amount, then use our Ultimate Financial Calculator.
Since the calculator will solve for multiple unknowns, it can easily be used to answer the following questions:
This calculator will solve for any one of four possible unknowns: "Amount of Loan", "Total Scheduled Periods" (term), "Annual Interest Rate" or the "Periodic Payment".
Enter a '0' (zero) for one unknown value.
The term (duration) of the loan is a function of the "Total Scheduled Periods" and the "Payment Frequency". If the loan is calling for monthly payments and the term is four years, then enter 48 for the "Total Scheduled Periods". If the payments are made quarterly and the term is ten years, then enter 40 for the "Total Scheduled Periods".
Normally you would set the "Payment Method" to "Arrears" for a loan. This means that the monies are lent on one day and the first payment isn't due until one period after the funds are received.
If the first payment is due on the day the funds are available, then set "Payment Method" to "Advance". This is typical for leases.
The "Amortization Method" should be set to "Normal" (level payments) unless you have a specific reason to set it to another method. &Fixed Principal" causes the amount allocated to principal to be the same each period which result in decreasing payments.
The Total Interest and Total Principal & Interest at the bottom of the calculator itself are approximations. The numbers do not include final payment rounding. Please see the schedule for the exact principal and interest amounts as well as any rounding amount required. The difference is greatest when solving for term, otherwise, the difference is usually pennies and not more than a dollar or two.
On a more general note, we have been discussing details about loans, some structured with unusual details, over several decades. At this point, we believe our software calculators can create a schedule for any custom loan that exists. If you have a loan with unusual terms, please ask.
