What's inside

The math your lender runs, in your hands.

Most calculators show you a payment. Drivewise shows you whether the deal will actually approve — and what to change if it won't.

Feature

Approval confidence gauge

A weighted score across credit, DTI, LTV, residual income, and term — tuned to match what underwriters actually flag.

Feature

Stress tests, not vibes

See how the deal holds up under +2% APR, a smaller down payment, or a 20% income drop — before you sign.

Feature

Hard-stop guardrails

We tell you when a deal exceeds lender thresholds — and what specifically blocks it (DTI, LTV, or both).

Feature

Find My Price mode

Flip a switch and Drivewise sweeps the price range that fits your finances — no more guessing.

Feature

Target solver

Pick 70%, 80%, or 90% confidence — we calculate the exact down payment to get you there.

Feature

Vehicle catalog

Browse curated vehicles ranked by your approval likelihood. Shift any car into your scenario in one click.
