Estimate principal and interest and know what this calculator does not include

Illustrative payments exclude taxes, insurance, HOA, and investor overlays. Sky keeps assumptions visible so you can export worksheets for your advisor before you lock or apply.

Professional calculator hygiene

Three labels Sky applies so numbers do not mislead offers

National sites bury PI vs. PITI in footnotes. Sky separates payment scope, lock timing, and documentation truth—the same triage wealth clients expect before signing.

Scope of payment

Principal and interest here; escrow and MI are modeled separately so cash to close is not understated.

Rate is illustrative

Market grids move daily; your lock confirmation and LE control actual pricing, points, and credits.

ARM honesty

Teaser inputs are not worst case caps—model fixed years, index, margin, and ceiling with your banker.

Payment calculator

Enter loan amount, APR, and term in years. Results update as you type.

Estimated principal & interest: / month

Illustrative only. Not a commitment to lend. APR and payment depend on credit approval, points, and program.

Adjustable-rate versus fixed-rate mortgage comparison
ARM payments can change after the fixed introductory period—model worst case caps with your banker.

How to use the result

Compare the payment to gross monthly income only as a rough guardrail, then refine with actual taxes, insurance quotes, and HOA for your property.

If you plan to itemize deductions, consult a tax advisor on how mortgage interest treatment may affect your net housing cost.

  1. PI vs. PITI Confirm which inputs your scenario includes before comparing to a Loan Estimate.
  2. ARM phases Model fixed years, index and margin assumptions, and worst case caps separately from the teaser rate.
  3. Extra payments Note whether your goal is shorter term or lower total interest; some investors recast instead of re-amortizing.
