🏦 Ultimate Amortization Calculator
Feature-packed schedule builder: payment frequency, interest-only & balloon options, extra payments (monthly/annual/one-time), escrow (taxes/insurance/PMI), fees, start date, and rate changes. Export CSV and print.
You can use either or both; total months is computed.
Per-period extra is applied every payment. Annual extra is added on the chosen month each year (based on start date). One-time extra triggers on the nth payment.
Rate Changes (optional)
When APR changes: if Recast=1, payment is recalculated for remaining term; otherwise payment stays the same and term adjusts.
Tip: Fill only what you need—advanced fields are optional.
