Compare loan offers side by side

Run the same offer through a generic amortizing-loan calc, pull the full schedule, then normalize the APR so two offers are comparable.

Workflow

Step 1 of 3

Loan / Amortization Calculator

Compute payoff totals for a candidate loan offer.

loan({"principal": 100, "annual_rate_pct": 0.07})

Step 2 of 3

Loan Amortization Schedule

Generate the full principal/interest schedule for that offer.

amortization_schedule({"principal": 100, "annual_rate": 0.07})

Step 3 of 3

Effective Rate (APR <-> APY)

Convert the offer's nominal APR into an effective rate for comparison.

effective_rate({"mode": "to_apy", "apr": 0.07, "apy": 100})
