Inputs
Fill the fields, then generate a schedule.
Large: 3 columns • Small: 2 columns • Mobile: 1 column
Starting balance for the schedule.
Nominal annual rate used per period.
How many payment rows to produce.
First payment date before adjustments.
Controls interest per period and dates.
Select how payments are split each period.
Extra amount applied directly to principal.
Added to the first payment row.
Added to every payment row.
Used only for “Balloon at end”.
Adjusts weekend dates.
Pushes the start date by set days.
Rounding for displayed numbers.
Custom Payment (optional)
Override the computed periodic payment with your own amount.
Used when custom payment is enabled.
Tip: If your payment is too low to cover interest, the balance may not reduce. The schedule will flag this and stop to avoid misleading results.

Formula Used
  • Periodic rate: r = (annualRate / 100) ÷ periodsPerYear.
  • Fixed amortized payment: P = r·A ÷ (1 − (1+r)−n) when r > 0.
  • Zero-rate case: P = A ÷ n.
  • Interest each period: I = balance · r.
  • Principal: principal = payment − interest (plus any extra payment).
  • Ending balance: end = begin − principal − extra.
  • Balloon: payment targets the balloon, then the last row clears remaining balance.

Payment schedules improve planning accuracy

A schedule turns a single amount into dated cash flows you can track. Enter the starting balance, annual rate, payment count, and start date to generate each line. Every row shows payment, interest, principal, fees, and the ending balance. This format supports budgeting, forecasting, and documentation for decisions.

Frequency changes both timing and interest

Frequency controls how often interest is applied and when balances fall. The periodic rate is the annual rate divided by periods per year, such as 12 for monthly or 26 for biweekly. A 12% annual rate becomes 1% per month or about 0.4615% per biweekly period. With more frequent payments, principal can decline sooner, reducing cumulative interest.

Fees and extra payments shift totals and payoff

Fees increase cash outflow but do not reduce the balance. A one‑time fee is added to the first payment, while recurring fees appear on every row. Extra payments are applied directly to principal, lowering future interest because interest is computed on the remaining balance. If you add 50 each period on a 25,000 balance, the payoff date may move forward and total interest typically falls.

Schedule types match common lending structures

Fixed amortized schedules keep the base payment steady and gradually increase the principal share. Equal‑principal schedules keep principal constant, so payments start higher and decline. Interest‑only schedules pay interest each period and clear principal in the final row. Balloon schedules target a remaining balance, then pay that balloon at the end. Custom payment mode lets you test real payment offers quickly.

Exports and charts make results easier to share

Use the table to verify row‑by‑row values and spot the point where principal accelerates. The balance chart clearly visualizes the payoff path, while cumulative interest shows the cost of time. CSV export works well for spreadsheet models and scenario comparisons, and the PDF is convenient for proposals or client files. Weekend adjustment can move dates forward or backward, improving calendar realism without changing the interest math.

FAQs

1) What does the periodic payment represent?
It is the base scheduled payment for the selected type and frequency. Fees and extra payments are added on top, so the cash paid per period can be higher than the base amount.

2) Why can the schedule end before the planned number of payments?
If extra payments reduce the balance to zero, the schedule stops early and the payoff date advances. The final row is adjusted so the ending balance reaches exactly zero.

3) What happens if my custom payment is too low?
If the payment cannot cover interest, the balance may not decline. The calculator flags this situation and stops to avoid showing an unrealistic payoff path.

4) How are fees handled in the table?
One‑time fees appear only in the first row. Recurring fees are added to every row’s payment total but do not reduce principal, so they increase total paid without lowering the balance.

5) How are weekends handled for payment dates?
You can keep dates unchanged, move weekend dates to the next business day, or move them to the previous business day. This adjustment changes displayed dates, not the interest formula.

6) Can I use this for invoices, subscriptions, or leases?
Yes. Any repeating payment plan can be modeled by choosing a frequency, adding fees, and using custom payments if needed. Use exports to share the schedule with clients or teammates.
