Required payment = principal & interest + that loan's mortgage insurance + property costs (taxes $0.00, insurance $0.00, HOA $0.00, maintenance $0.00). Planned payment adds recurring extra principal. Loan cost = net upfront costs + interest + mortgage insurance; principal repayment builds equity and property costs continue after payoff, so neither is counted. Mortgage insurance by scenario: Scenario A — no extras — No mortgage insurance; Scenario B — $400/mo extra — No mortgage insurance.

Scenario B — $400/mo extra$0+$400−$159,602−$159,6029 yr soonerNot applicable — extra-payment strategy

Break-even is the first month a scenario's economic cost (net upfront costs + interest + mortgage insurance) falls at or below the baseline's. It only applies when both scenarios finance the same principal and one pays more upfront for a lower rate; paying extra principal on identical terms has no closing-cost recoup period.

Extra-payment strategy

Scenario A — no extras
  • No extra principal payments — scheduled payments only.
Total extra principal $0 · payoff on schedule · interest $463,354
Scenario B — $400/mo extra
  • $400 every month from payment 1 until payoff
Total extra principal $100,400 · payoff 9 yr early · interest $303,752 · saves $159,602 vs baseline

What this means for you

Client decision summary
  Estimated cash to close: $0.00
    No unfinanced costs, prepaids or borrower contribution are entered.
  Monthly difference: +$400.00
    Planned monthly outflow $2,398.20 → $2,798.20, including any recurring extra principal.
    Required payment difference $0.00: $2,398.20 → $2,398.20
  Break-even on cash spent: Not applicable — this plan increases planned payment
    No unfinanced transaction costs are entered, so there is nothing to earn back.
  5-year impact: $3,908 lower financing cost
    Financing cost through Aug 2031: $116,110 → $112,202.
    Balance after 5 years $372,218 → $344,310

  Benefits
    Faster payoff (9 yr sooner) — Aug 2056 → Aug 2047.
    Lower financing cost ($3,908) — Less financing cost through 5 years (upfront costs, interest and mortgage insurance).
    More equity built ($27,908) — The balance is lower at the five-year mark, so more equity has been built by then.
  Watch-outs
    Higher monthly commitment (+$400.00) — Planned outflow $2,398.20 → $2,798.20, including extra principal, which is voluntary.
  Estimated — not a Loan Estimate or Closing Disclosure.

Appendix — how these numbers were calculated

HOW THESE NUMBERS WERE CALCULATED

WHAT IS BEING COMPARED
  Reference loan: Scenario A — no extras — every difference below is measured against this loan
  Horizon: 5 years — 60 months — every scenario is counted through one shared calendar cutoff of August 2031, anchored on the earliest first payment (September 2026)
  Like-for-like: yes — Every scenario finances the same starting principal, so interest, financing cost and break-even are directly comparable.
  Largest difference in financed principal: $0

HOW EACH DIFFERENCE IS DEFINED
  Payment difference: this loan's required payment − the reference loan's required payment
  Interest difference: reference interest − this loan's interest, over the same number of months
  Financing cost: net transaction cost + interest + mortgage insurance — principal is excluded because repaying principal is not a cost, and property costs are excluded because they continue either way
  Break-even: the first month this loan's cumulative financing cost falls at or below the reference loan's and stays there — only reported when both loans finance the same principal

POSITION AT 5 YEARS
  Scenario A — no extras: financing cost $116,110 — interest $116,110 · balance $372,218 · cumulative cash paid $143,892
  Scenario B — $400/mo extra: financing cost $112,202 — interest $112,202 · balance $344,310 · cumulative cash paid $167,892

WHETHER A RECOMMENDATION IS SUPPORTED
  Lowest-cost winner shown: yes — the loans finance the same principal and use programs this model handles fully
  Payment winner shown: yes — monthly payment is comparable regardless of the amount financed

SCENARIO A — NO EXTRAS — CALCULATION DETAIL
  Inputs as the engine read them
    Financed loan amount (principal): $400,000
    Annual interest rate: 6.00%
    Monthly interest rate: 0.500000% — annual rate ÷ 12, carried at full precision and never rounded mid-schedule
    Term: 30 years = 360 payments
    First payment date: September 28, 2026
    Loan program: conventional
    Original property value: not entered — only used for the mortgage-insurance cancellation tests
  Scheduled principal & interest
    Formula: P × i ÷ (1 − (1 + i)^−n) — P = principal, i = monthly rate, n = number of payments. At a 0% rate it becomes P ÷ n.
    Unrounded payment: 2398.202101
    Billed payment used in the schedule: $2,398.20 — the unrounded payment rounded to the cent
    Required monthly payment: $2,398.20 — P&I $2,398.20
    Planned monthly payment: $2,398.20 — required payment + $0.00 of recurring extra principal
  Fees, points and credits
    Closing costs entered: $0
    Discount points: 0% of $400,000 = $0
    Lender credits: − $0
    Net transaction (financing) cost: $0 — closing costs + points − lender credits; this is the only cost figure inside financing cost and break-even
    Prepaids and initial escrow funding: $0
    Borrower cash contribution to principal: $0
    Cash due at closing: $0 — net transaction cost + prepaids/escrow + borrower contribution. The recoup ledger is measured against UNFINANCED TRANSACTION COSTS only, not against this cash figure.

    Financing cost = net transaction cost + interest + mortgage insurance: reconciles
