What to do next

Break-Even Point1.1 monthsExcellent

Pays for itself inside a year.

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 1.1 months. Before that point the upfront cost has not been recovered.

Is this good or bad?

Yes — this is a strong result by U.S. standards. Pays for itself inside a year.

What's the risk?

Low risk. Nothing here needs urgent attention — protect the position you are in.

  1. 1

    Compare to how long you'll stay

    If you may move first, the upfront cost is a loss.

  2. 2

    Ask for a no-cost option

    A slightly higher rate with no fees can beat paying costs upfront.

  3. 3

    Confirm all fees are included

    Title, escrow and origination all belong in the break-even math.

  4. 4

    Re-run if rates move 0.25%

    Break-even is very sensitive to the rate spread.

Result Intelligence

Understand your result

  • Your net gain from switching is $2,567.98. It reflects your monthly obligation and total cost of credit at today's rates.
  • Small changes in rate or term can meaningfully change lifetime interest — always compare offers.

  4. Compound Interest Calculator

Ways to improve your result

  • Shop 3+ lenders — median rate spread on the same borrower is 0.5–1.0%.
  • Choose a shorter term when cash flow allows — total interest drops sharply.
  • Autopay usually earns a 0.25% rate discount.

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.

How to read your result

Bank Account Switching Savings 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?

Extra interest = Balance × (1 + New APY)^Years − Balance × (1 + Old APY)^Years. Gross gain = Extra interest + Bonus. Net gain = Gross gain − Gross gain × Tax rate − Closing fee − Hours × Hourly value. Break-even months = Switching cost ÷ [(First-year advantage + Bonus) ÷ 12].

How it works

Most people leave money in a legacy savings account paying a fraction of a percent because switching feels like work. This calculator puts a price on both sides of that inertia: the compounded rate advantage and any sign-up bonus on one side, and the closing fees, the taxes owed on the extra income, and the value of the hours you spend moving direct deposits and autopays on the other. Bank sign-up bonuses are taxable — the bank reports them on Form 1099-INT or 1099-MISC — so the headline offer is worth less than it looks at your marginal rate. Bonuses also usually carry conditions such as a qualifying direct deposit or a minimum balance held for 60 to 90 days, and closing the account early can claw the bonus back.

Step-by-step guide

  1. 1Enter the loan or principal amount you're evaluating.
  2. 2Set the interest rate (APR) and repayment term.
  3. 3Adjust optional inputs like fees, extra payments, or down payment.
  4. 4Review the monthly payment, total interest, and full amortization.
  5. 5Copy, share, or print the results for your records.

Example calculation

Example: Moving $25,000 from a 0.40% legacy savings account to a 4.40% online bank with a $300 bonus.

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

Comparison tables

APR vs APY: Why the Two Numbers Differ

APR is the cost of borrowing under Regulation Z. APY is the return on savings under Regulation DD (Truth in Savings). Only APY includes compounding.

APR vs APY: Why the Two Numbers Differ
FactorAPR (Annual Percentage Rate)APY (Annual Percentage Yield)
Used forLoans, mortgages, credit cardsSavings, CDs, money market accounts
Includes feesYes — points and most finance chargesNo — fees are disclosed separately
Includes compoundingNoYes
Governing ruleRegulation Z / Truth in Lending ActRegulation DD / Truth in Savings Act
RelationshipNominal rate + fees, annualizedAPY = (1 + r/n)^n − 1

Bottom line: Compare loans on APR and deposits on APY. Comparing an APR to an APY always understates the real gap.

Decision guide

Should I Pay Down Debt or Invest First?

Ordering matters more than the amount you can spare.

  1. 1Do you have a full employer 401(k) match available?

    Yes: Capture the match first — it is an instant 50%–100% return.

    No: Continue.

  2. 2Do you carry any debt above roughly 8% APR (credit cards, personal loans)?

    Yes: Attack that debt next. No market return reliably beats a guaranteed 20% credit-card APR.

    No: Continue.

  3. 3Do you have a 3–6 month emergency fund?

    Yes: Continue.

    No: Build the fund before extra investing — it prevents new high-APR debt.

  4. 4Is your remaining debt below about 5% APR (mortgage, subsidized student loans)?

    Yes: Invest the surplus in tax-advantaged accounts.

    No: Split the surplus: half to debt, half to investing.

Bottom line: Match → high-APR debt → emergency fund → invest. Only low-rate debt should ever compete with investing.

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.
