Worthune

For advisors, planners & educators

Hand clients a calculator
you can stand behind

Client conversations go better when the client can move the sliders themselves. Worthune's 27 scenario calculators are free to share, take prefilled inputs in the URL, and — unlike the average web calculator — every one documents exactly what it computes, so you're never endorsing a black box.

🔍

No black boxes

Every calculator links its published spec: the formulas, the assumptions, what it deliberately leaves out. 'Where does this number come from?' now has a one-click answer.

📎

Prefill and send

Build a link with a client's real numbers (/scenarios/sabbatical?currentSavings=80000) and send it. They land mid-scenario, sliders live — not on a blank form.

🏛️

Current-year constants, cited

IRS and SSA figures come from a sourced, dated registry, updated when the rules change — and every model revision is public. Diligence material your compliance reviewer will actually like.

Start with a link, grow into the API

Day one is just a link. When your practice builds a client portal, the same verified models are one POST away.
