Free amortisation calculator balance software for windows

Auto Loan Calculator 1 is designed for Excel which will support you to plan your next car purchase. Calculate the amount you will need to finance, based on sales price, destination charge, fees, sales tax, down payment, cash rebate, and trade-in value of an older auto. Use the Payment Calculator worksheet to create an amortization table based on the amount you've financed. Analyze different loans to choose a suitable monthly payment and minimize the total interest.

Amortization Schedule for Excel 1.5.5 is designed with an aim to create an amortization schedule or payment schedule for a fixed-rate loan, with optional extra payments. The payment frequency can be annual, semi-annual, quarterly, bi-monthly, monthly, semi-monthly, bi-weekly, or weekly. Values are rounded to the nearest cent, or the rounding can be turned off. The last payment is adjusted to bring the balance to zero. The compound period can be set based on US or Canadian mortgages. You can select whether payments are due at the end or beginning of the payment period.

Major Features:

1. Interest Rate, Compound Period, and Payment Period
   • Usually, the interest rate that you enter into an amortization calculator is the nominal annual rate. However, when creating an amortization schedule, it is the interest rate per period that you use in the calculations, labeled rate per period in the above spreadsheet.
   • Basic amortization calculators usually assume that the payment frequency matches the compounding period. In that case, the rate per period is simply the nominal annual interest rate divided by the number of periods per year. When the compound period and payment period are different (as in Canadian mortgages), a more general formula is needed (see my amortization calculation article).
2. Negative Amortization
   • There are two scenarios in which you could end up with negative amortization in this spreadsheet (interest being added to the balance). The first is if your payment isn't enough to cover the interest. The second is if you choose a compound period that is shorter than the payment period (for example, choosing a weekly compound period but making payments monthly).
3. Rounding
   • A loan payment schedule usually shows all payments and interest rounded to the nearest cent. That is because the schedule is meant to show you the actual payments. Amortization calculations are much easier if you don't round. Many loan and amortization calculators, especially those used for academic or illustrative purposes, do not do any rounding. This spreadsheet rounds the monthly payment and the interest payment to the nearest cent, but it also includes an option to turn off the rounding (so that you can quickly compare the calculations to other calculators).
   • When an amortization schedule includes rounding, the last payment usually has to be changed to make up the difference and bring the balance to zero. This might be done by changing the Payment Amount or by changing the Interest Amount. Changing the Payment Amount makes more sense to me, and is the approach I use in my spreadsheets. So, depending on how your lender decides to handle the rounding, you may see slight differences between this spreadsheet, your specific payment schedule, or an online loan amortization calculator.
4. Extra Payments
   • With a loan amortization schedule set up in Excel, it is really quite simple to handle arbitrary extra payments (prepayments or additional payments on the principal). You simply add the extra payment to the amount of principal that is paid that period. For fixed-rate loans, this reduces the balance and the overall interest, and can help you pay off your loan early. But, the normal payment remains the same (except for the last payment required to bring the balance to zero - see below).
   • This spreadsheet assumes that the extra payment goes into effect on the payment due date. There is no guarantee that this is how your lender handles the extra payment! However, this approach makes the calculations simpler than prorating the interest.
5. Zero Balance
   • One of the challenges of creating a schedule that accounts for rounding and extra payments is adjusting the final payment to bring the balance to zero. In this spreadsheet, the formula in the Payment Due column checks the last balance to see if a payment adjustment is needed. In words, this is how the payment is calculated:
   • If you are on your last payment or the normal payment is greater than (1+rate)*balance, then pay (1+rate)*balance, otherwise make the normal payment.
6. Payment Type
   • The "payment type" option lets you choose whether payments are made at the beginning of the period or end of the period. Normally, payments are made at the end of the period. If you choose the "beginning of period" option, no interest is paid in the first payment, and the Payment amount will be slightly different. You may need to change this option if you are trying to match the spreadsheet up with a schedule that you received from your lender. This spreadsheet doesn't handle prorated or "per diem" periods that are sometimes used in the first and last payments.
7. Loan Payment Schedule
   • One way to account for extra payments is to record the additional payment. This spreadsheet includes a second worksheet (the Loan Payment Schedule) that allows you to record the actual payment instead. (Just in case you find that more convenient.) For example, if the monthly payment is $300, but you pay $425, you can either record this as an additional $125, or use the Loan Payment Schedule worksheet to record the actual payment of $425.
