Loan details and the amortization schedule

Open a loan's editor to see its full amortization schedule: monthly principal and interest, total interest, payments made, and an extra-payment slider that shows how much sooner you could pay it off. The slider is a what-if; it doesn't change your loan.

Enter a loan and drag the extra-payment slider. Same formula as the app.

How the payment is calculated

Monthly P&I = P × r × (1 + r)ⁿ ÷ ((1 + r)ⁿ − 1)

  • P is Purchase Value, the original loan amount.
  • r is the monthly rate: Interest Rate ÷ 100 ÷ 12.
  • n is Loan Term (months).

Each month, interest is the remaining balance × r, the rest of the payment goes to principal, and the balance drops by that principal. The last payment absorbs any rounding. Example: $320,000 at 6.25% for 360 months gives a monthly P&I of $1,970.30. In month 1, $1,666.67 is interest and $303.63 is principal.

This is principal and interest only. Taxes and insurance (escrow) are not part of it. The same number shows as Calculated P&I in the editor.

The summary cards

Monthly P&I
The payment from the formula above.
Total Interest
Interest added up over every scheduled payment.
Total Cost
The original amount plus total interest.
Payments Made
Whole months from Loan Start Date to today, out of the term. Shows once at least one month has passed.
Behind Schedule / Ahead of Schedule
Your latest recorded balance compared with the balance the schedule expects for that month. Ahead means you owe less than scheduled.

Chart and table

Switch between Chart and Table at the top. The chart shows the scheduled balance with a dot for today, cumulative principal and cumulative interest, your actual balance from the loan's history when it differs from the schedule, and the extra-payment line when you use the slider.

The table lists every payment: #, Date, Payment, Principal, Interest, Balance, and Actual (your recorded balance for that month, green when below schedule and red when above). The current month is highlighted.

Extra payment what-if

Under the chart, Extra payment what-if shows what paying more would do. Choose a mode and drag the slider:

  • $ / month: an extra amount every month, up to about one extra payment.
  • payments / year: 0 to 12 extra full payments a year, spread evenly across the months (one a year adds P&I ÷ 12 to each month).

The extra starts today, from the balance the schedule says you owe now, and repeats every month. FIYR shows the New payoff month, how much sooner that is, and the Interest saved from today on.

Keep the actual line useful

The Actual column and the ahead/behind card come from the loan's monthly values. Update the balance each month in the monthly value review and they track your real progress.

Common questions

Why don't I see an amortization schedule for my loan?

It needs Interest Rate, Loan Term (months) and Purchase Value (the original loan amount). Open ⋯, Edit details, fill them in and save.

Are extra payments saved?

No. The extra-payment slider is a calculator only. To record a real extra payment, update the loan's balance.

Why is my Monthly P&I lower than my mortgage payment?

Monthly P&I is principal and interest only. Your lender's payment usually also includes property taxes and insurance (escrow).

Why does it say I'm behind schedule?

Your latest recorded balance is higher than the schedule expects. Check that Purchase Value, Loan Start Date and the rate match your loan, and that this month's balance is current.
