Finance tools built for
investors, not accountants.
Most finance calculators are either paywalled, account-gated, or quietly harvest your data. WealthifyX exists to fix that — free, private, precise tools that work for anyone trying to understand their money.
What we stand for.
Four principles that govern every decision we make — from how we write formulas to how we pay the bills.
Privacy by Design
We never see your numbers. Every calculation runs entirely in your browser — no servers, no databases, no logs. Close the tab and it never existed.
Zero Accounts Required
Financial planning should be frictionless. Every tool on this site is available immediately — no sign-up wall, no email, no credit card, ever.
Institutional-Grade Math
Our calculators use the same formulas professional analysts use — no rounding drift, no shortcuts, no simplified assumptions that silently skew your results.
Free Forever
Precision tools should be accessible to everyone. WealthifyX is funded through contextual affiliate partnerships — not by charging you, not by selling your data.
How is this free?
WealthifyX is a labor of love. We believe professional-grade financial modeling should be available to every retail investor — not behind a paywall or a "free trial" that expires when you need it most.
We sustain the site through contextual affiliate partnerships with brokers and financial service providers we personally use and trust. If you choose to open an account through one of our links, we may earn a commission at no cost to you.
This keeps the math pure, the tools free, and your data exactly where it belongs: on your own device.
Why our numbers are different.
Most free calculators take shortcuts that silently skew long-term projections. Here's exactly what we do differently.
No intermediate rounding
We carry full floating-point precision through every calculation step. Rounding only happens at display time — never inside the formula.
Industry-standard formulas
Every calculator uses the same formulas taught in CFA and CFP curriculum — not simplified approximations that introduce hidden error.
Built by someone who trades
WealthifyX was built by a developer with a background in technical analysis and options trading. We know what numbers matter.
