# Mortgage points calculator

Compare two actual rate-and-points quotes at the same principal and term. Enter both offered rates; a point does not buy a fixed rate reduction.

Quote A minus Quote B: borrowing cost

+$764.36 through month 60

Positive means the second option costs less; negative means it costs more. Cost includes entered fees and interest, with the remaining balance accounted for.

- **Monthly payment difference**: +$49.05
- **Quote A balance at horizon**: $280,832.93
- **Quote B balance at horizon**: $280,011.72

## Payment, debt and cost together

**Both options start now; horizon is month 60. USD, rounded to cents.**

| Measure | Quote A | Quote B |
| --- | --- | --- |
| Opening debt | $300,000.00 | $300,000.00 |
| Monthly principal and interest | $1,896.20 | $1,847.15 |
| Loan costs paid now | $0.00 | $3,000.00 |
| Loan costs added to debt | $0.00 | $0.00 |
| Months until scheduled payoff | 360 | 360 |
| Cash paid through horizon | $113,772.24 | $113,829.10 |
| Debt remaining at horizon | $280,832.93 | $280,011.72 |
| Borrowing cost through horizon | $94,605.18 | $93,840.82 |
| Lifetime interest plus entered fees | $382,633.47 | $367,974.58 |

At month 60, Quote A minus Quote B is **−$56.85 in cash paid** and **+$764.36 in borrowing cost**. Across both full repayment terms, the borrowing-cost difference is +$14,658.89. A positive difference favors the second option.

### When does the second option first cost less?

- Cumulative cash paid: month 62.
- Borrowing cost including remaining debt: month 48.

These are the first months with a strictly positive difference, evaluated at monthly payment dates. Month 0 means the upfront costs already differ. A first crossing can reverse later, especially after the original loan is paid off. It is not a promise of permanent savings.

## Method and limits

Borrowing cost at a horizon = cumulative loan payments + cash-paid loan costs + remaining debt − starting principal before financed costs. This equals interest accrued through that month plus the entered costs. Financed costs are included once through the larger debt. Repayment of principal is not treated as a borrowing cost.

The model uses fixed rates, monthly interest (annual note rate ÷ 12), and payments at the end of each month. Payments are calculated at full precision; displayed values are rounded. After payoff, that option contributes no more payments. There is no discount rate, investment return, tax deduction or inflation adjustment.

One discount point is 1% of the shared loan principal. Enter the actual note rate offered with each points amount. Other loan costs and lender credits are separate; credits cannot exceed the entered costs. Both quotes have the same principal and term, and all net closing costs are paid in cash.

Property taxes, homeowners or vehicle insurance, mortgage insurance, escrow deposits/refunds and ongoing fees are excluded. Separate unchanged ownership costs from transaction costs. Enter any relevant prepayment or refinancing charge once; check the actual contract before using this estimate.

## Questions

### Are these lender offers?

No. Defaults illustrate the method. Enter your own quote and check its loan disclosures. Eligibility and approval are not modeled.

### Why can a lower payment cost more?

Extending repayment can leave more debt at the comparison horizon and add interest over the full term. Review both balances and total costs.

### What is excluded?

Taxes, insurance, escrow, cash-out proceeds, investment returns, variable rates, daily-interest timing, skipped payments and any fee not entered. This is not a complete ownership budget.

### Are my inputs saved?

The form uses a URL query. Inputs can remain in your browser history and hosting logs. Scenario pages omit analytics and use private, no-store responses; copying a scenario URL shares its inputs.
