What to do next
You need to stay five years for this to pay off.
Benchmark: A refinance or points purchase only pays off if you hold past the break-even month. — CFPB mortgage shopping guidance
What this means
Break-even lands at 59.9 months. Before that point the upfront cost has not been recovered.
Is this good or bad?
It is acceptable, but there is clear room to improve. You need to stay five years for this to pay off.
What's the risk?
Moderate risk. You are inside acceptable limits but without much cushion.

Compare to how long you'll stay
If you may move first, the upfront cost is a loss.

Ask for a no-cost option
A slightly higher rate with no fees can beat paying costs upfront.
- 3
Confirm all fees are included
Title, escrow and origination all belong in the break-even math.
- 4
Re-run if rates move 0.25%
Break-even is very sensitive to the rate spread.

Common U.S. scenarios
Texas family
$95k household income, two auto loans. Refinancing a 22% APR card into a 5-year 11% personal loan saves ~$4,200 in interest.
California renter
Single filer earning $110k in LA — a 45% DTI locks out most conventional mortgages until credit-card debt is paid down.
Florida retiree
Fixed Social Security + pension. Keeping utilization under 10% preserves the 780+ FICO needed for the best HELOC rates.

Mortgage Points Calculator: Your result is an estimate of the payment, interest, or payoff that matches the inputs above. It's a directional number to compare offers — not a lender quote.
What your result means
- A lower monthly payment often means a longer term and more total interest paid over the life of the loan.
- A higher APR compounds faster — even a 0.5% difference can add thousands over 30 years.
- Total interest is a better comparison metric than the monthly payment alone.
How does the formula work?
Cost = points × 1% × loan. Savings = Old P&I − New P&I at (rate − points × reduction). Break-even (months) = Cost / Monthly savings.
How it works
Decide whether buying discount points to lower your mortgage rate is worth it.
Step-by-step guide
- 1Enter the loan or principal amount you're evaluating.
- 2Set the interest rate (APR) and repayment term.
- 3Adjust optional inputs like fees, extra payments, or down payment.
- 4Review the monthly payment, total interest, and full amortization.
- 5Copy, share, or print the results for your records.
Example calculation
Example: 1 point on $300k @ 7% → 6.75%.
Who should use this calculator?
- Home buyers comparing mortgage scenarios
- Borrowers evaluating a personal, auto or student loan
- Anyone paying down credit-card debt
- Financial advisors preparing client scenarios
When should you use it?
- Before signing a loan or mortgage agreement
- When shopping rates across lenders
- When considering extra payments or refinancing
- When budgeting for a large purchase
What affects the result?
- Interest rate (APR) and how it compounds
- Loan term — longer terms lower the payment but raise total interest
- Down payment or upfront amount
- Fees, points and insurance included in the APR
- Extra or bi-weekly payments
Compare three scenarios
| Scenario | Inputs | Outcome |
|---|---|---|
| Conservative | $250k loan, 30yr, 7.5% APR | $1,748/mo · $379k interest over 30yr |
| Balanced | $250k loan, 20yr, 7.0% APR | $1,938/mo · $215k interest — saves ~$164k |
| Aggressive | $250k loan, 15yr, 6.5% APR | $2,178/mo · $142k interest — saves ~$237k |

Comparison tables
Buying vs Renting a Home in the USA
Homeownership builds equity but carries costs renters never see. HUD and the CFPB both recommend comparing the full monthly cost of ownership, not just the mortgage payment.
| Factor | Buying | Renting |
|---|---|---|
| Upfront cash | 3%–20% down plus 2%–5% closing costs | First month plus a security deposit |
| Monthly cost | Principal, interest, property tax, insurance, HOA, PMI (PITI) | Rent plus renters insurance |
| Maintenance | Budget 1%–2% of home value per year | Landlord's responsibility |
| Tax benefit | Mortgage interest and property tax deductible if you itemize (IRS Pub. 936) | No federal deduction |
| Break-even horizon | Typically 4–7 years before ownership wins | Cheaper below the break-even horizon; full mobility |
Bottom line: Ownership usually wins once you pass the break-even horizon and stay put. Below it, renting and investing the difference commonly produces more net worth.
Fixed vs Variable Rate: Which Costs Less?
Fixed rates lock your payment for the life of the loan. Variable (adjustable) rates start lower but move with an index such as SOFR or the Prime Rate published by the Federal Reserve.
| Factor | Fixed rate | Variable / adjustable rate |
|---|---|---|
| Starting rate (2025 typical) | Higher — around 0.25%–0.75% above the intro ARM rate | Lower teaser rate for 3, 5, 7 or 10 years |
| Payment stability | Identical principal & interest every month | Resets at each adjustment period, subject to caps |
| Best when | You keep the loan more than 5–7 years, or rates are falling slowly | You expect to sell, refinance or pay off before the first reset |
| Worst case | You overpay if market rates drop and you never refinance | Payment shock at reset — caps commonly allow +2% per adjustment, +5% lifetime |
| Disclosure rule | APR disclosed under Regulation Z (Truth in Lending) | CFPB requires a Consumer Handbook on Adjustable-Rate Mortgages (CHARM) booklet |
Bottom line: Run both scenarios in the calculator. If the total interest paid over your expected holding period is within about 1% of each other, take the fixed rate — the certainty is worth more than the small savings.
Decision guide
Should I Buy or Keep Renting?
HUD and CFPB guidance points at four gating questions.
1Will you stay in the area at least 5 years?
Yes: Continue.
No: Rent. You likely will not clear transaction costs.
2Do you have the down payment plus 3–6 months of expenses left over?
Yes: Continue.
No: Rent and keep building reserves — closing wipes out thin savings.
3Is total PITI (plus HOA and maintenance) under 28% of gross monthly income?
Yes: Continue.
No: Lower the price target or wait — you would be cost-burdened.
4Is your job and income stable, with a DTI under 43%?
Yes: Buy.
No: Rent until income stabilizes.
Bottom line: Buy when time horizon, reserves, payment ratio and income stability all pass. Any single failure favors renting.
Common mistakes to avoid
- Mixing APR with the nominal rate — the APR includes fees.
- Entering annual rate as a decimal (e.g. 0.07 instead of 7).
- Forgetting taxes, insurance, HOA, or PMI when comparing homes.
- Ignoring extra payments — even $50/month can shave years off a loan.
Pro tips
- Compare APR — not just the nominal rate — across offers.
- Model a scenario with an extra $50–$100/month; the interest savings can be dramatic.
- Check the amortisation schedule to see when you cross the interest-vs-principal midpoint.
Why use this calculator
- Instantly compare loan offers side-by-side without a lender pitch.
- See the full amortization schedule — interest vs principal, month by month.
- Model extra payments and refinancing scenarios in seconds.
- 100% free, no signup, no credit pull, no data stored on our servers.
Limitations to keep in mind
- APR shown by a lender may differ due to fees, points and credit tier.
- Does not replace a Loan Estimate or Truth-in-Lending disclosure.
- Assumes fixed rate — variable-rate products may behave differently.
- Not a commitment to lend and not a substitute for lender underwriting.
Key terms explained
- APR (Annual Percentage Rate)
- The yearly cost of a loan expressed as a percentage — includes the interest rate plus most lender fees, so it's the fair number to compare offers with.
- Principal
- The amount you actually borrow (or currently owe), before any interest is added. Every payment splits between principal and interest.
- Amortization
- The schedule that shows how each payment is divided between interest and principal. Early payments are mostly interest; later payments are mostly principal.
- DTI (Debt-to-Income)
- Monthly debt payments divided by gross monthly income. U.S. lenders typically prefer a DTI at or below 36–43%.
- Escrow
- A lender-managed account that collects property taxes and homeowners insurance monthly, then pays them on your behalf when due.
Before you decide
- Confirm the quoted rate is APR (not just the note rate) so fees are included.
- Check whether the payment includes taxes and insurance (escrowed) or just principal + interest.
- Ask about prepayment penalties before committing to any extra-payment plan.
- Compare at least 3 lender offers — a 0.25% rate difference matters over 15–30 years.
