Quick primer

When you compare loans, focus on three things: the interest rate, the annual percentage rate (APR), and the itemized fees. The interest rate affects monthly payments; the APR attempts to show the annual cost of borrowing including some fees; and itemized fees (origination, application, closing, prepayment penalties) tell you what you’ll pay up front or during the loan. Together they reveal the loan’s real cost over its term.

Step-by-step process for comparing offers

  1. Gather the same information from each lender
  • Loan amount, repayment term, interest rate, APR, and a list of all fees (origination, application, underwriting, appraisal, closing, prepayment). Ask for the loan estimate or a written breakdown.
  • Use the same loan amount and term when comparing to keep apples-to-apples.
  1. Confirm what each lender includes in APR
  • APR is a standardized disclosure, but it doesn’t always include every charge. CFPB guidance notes APR includes interest and certain finance charges; some third‑party fees may be excluded. Treat APR as a first filter, not the final answer.
  1. Build a total-cost calculation
  • Total cost = principal + total interest paid over term + all fees you will pay (upfront and ongoing).
  • Use a spreadsheet or a loan calculator (many lenders and third‑party sites provide these). Confirm whether fees are financed into the loan (added to principal) or paid upfront — that affects cash flow and total interest.
  1. Compare monthly payment versus total cost
  • A lower monthly payment can come with a longer term that increases total interest.
  • If your goal is minimal total cost, prioritize shorter terms and lower fees even if monthly payments rise.
  1. Check for prepayment penalties or rate changes
  • Adjustable or teaser rates may be low initially and rise later. Make sure you model the rate schedule and any prepayment penalties that could block cheaper early payoff.
  1. Validate the lender’s reputation and underwriting conditions
  • Turnaround time, required collateral, customer service, and whether the lender will sell the loan affect your experience and future options.

Simple comparative example (step-by-step math)

Two 5-year personal loan offers for $20,000:

  • Loan A: 6.0% interest, APR 6.8% (includes $400 origination fee financed into loan). Monthly payment: $386.
  • Loan B: 6.5% interest, APR 6.5% (includes $100 upfront fee paid at closing). Monthly payment: $389.

Calculate total cost (principal + interest + fees):

  • Loan A: If the $400 fee is financed, total interest over 5 years on the financed balance will be slightly higher. Total interest ≈ $3,160; fees $400; total cost ≈ $23,560.
  • Loan B: Total interest ≈ $3,340; fees $100; total cost ≈ $23,440.

Result: Loan B costs about $120 less over 5 years even though its nominal rate is higher. This illustrates why APR and the itemized fee treatment matter. Use an amortization schedule to calculate exact numbers.

Checklist to use while shopping (what to ask and record)

  • Exact interest rate and whether it’s fixed or variable.
  • APR and definition of fees included in APR.
  • Itemized fees (amount and whether financed).
  • Repayment term and monthly payment.
  • Prepayment penalty, late fees, and any rate resets.
  • Collateral requirements or co-signer obligations.
  • Required insurance or escrow items.

Negotiation and practical tips from practice

  • Negotiate fees, not just the rate. In my practice I’ve seen lenders drop origination fees or waive application costs when borrowers present competing offers.
  • Improve credit and lower debt-to-income (DTI) before applying to get better rate tiers.
  • If you plan to refinance or pay off early, avoid loans with prepayment penalties. Document any verbal promises in writing.
  • Factor taxes and insurance only when they meaningfully change the loan (mostly relevant for mortgages).

When APR can mislead

  • APR assumes the loan runs the full term and that fees are financed in a standard way. If you plan to refinance or sell (common with mortgages), the APR may exaggerate long-term cost.
  • APR may not include late fees, default-related fees, or some third-party charges. Use the itemized fees list to confirm.

Loan type specifics (quick notes)

  • Mortgages: include closing costs, points, and mortgage insurance (if applicable). Compare APR but also run scenarios for 30‑year vs 15‑year terms. See our LTV guide on how loan size and equity affect pricing: https://finhelp.io/glossary/understanding-loan-to-value-ltv-and-its-role-in-mortgage-approval/.
  • Personal loans: fees are usually origination or application; APR often captures the financed origination fee.
  • Business loans: watch for personal guarantees and covenants that add indirect costs.

Red flags to avoid

  • Lenders unwilling to provide a written estimate or that give verbal-only APRs.
  • Unclear fee descriptions (e.g., “processing fee” with no amount or purpose).
  • Pressure tactics (“rate expires today”) — legitimate lenders provide written offers that last several days.

Tools and calculators

  • Use an amortization calculator to produce a payment schedule and total interest. Record both the financed fees and upfront fees.
  • Compare the net present value (NPV) of offers if you need a precise apples-to-apples cost comparison across offers with different fee timing.

Common borrower mistakes

  • Choosing by monthly payment alone without checking total interest and fees.
  • Ignoring the effect of financed fees (they increase the balance that accrues interest).
  • Not checking whether APR includes required third‑party charges.

Legal and regulatory references

Final decision framework (practical scoring)

  1. Eliminate offers with unacceptable terms (prepayment penalty, unclear fees, required insurance you don’t want).
  2. For the remaining offers, compute total cost over the term (don’t forget financed fees).
  3. If total costs are close, factor in lender service, speed, and flexibility.
  4. Use negotiation leverage—present the best competitive offer and ask for matching or better terms.
