Let us know below if you have an idea for an additional financial tutorial.

When you activate a "Normal Series", you can enter the total amount of the payment, deposit, withdrawal or investment.

Normal payments are first applied to outstanding interest, the remainder of the payment is then allocated towards outstanding principal.

When you activate an "Interest Only Series", the calculator will calculate the amount needed to pay the accrued interest for each payment period — depending on your selected compounding frequency. Depending on your selected compounding frequency, your payment amounts may vary for each period.

NOTE: Each payment amount or withdrawal amount will be displayed on the schedule (only).

When you activate a "Fixed Principal + Interest Series", you can specify the principal amount of payment. The calculator will calculate the accrued interest for the period and add it to the principal amount. The total payment (principal + interest) will be displayed on the schedule.

NOTE: The payment amounts will vary over time as the interest amount decreases with each paymment.

When you activate a "Principal First Series", you can enter the total amount of the payment, deposit or withdrawal in this window or on the main screen.

This type of payment will be applied towards reducing the outstanding principal. Payments are applied first to outstanding principal. Interest is paid after all principal is paid.

When you activate an "Amount Step Series", you can generate a series of cash flows that increase or decrease by a given amount after a specified number of payments or withdrawals.

Your amounts may vary over time and will be displayed on the schedule.

When you activate an "Percent Step Series", you can generate a series of cash flows that increase or decrease by a given percentage after a specified number of payments or withdrawals.

Your amounts may vary over time and will be displayed on the schedule.

When you activate a "Skip Series", this calculator will create a series that alternates between a number of "made" amounts and a number of "skipped" amounts.

NOTE: The "Monthly Skip" may be easier to use.
