— Why we built this
Not advice. Not a product. Just the numbers.
Most financial tools are either too stripped-down to trust or designed to sell something. We built Open Ledger to fill the gap: transparent calculations with every assumption on the table.
/ Three commitments
What this platform stands for
Assumptions printed, always
No fees, no products sold
Honest about the limits
Every output carries the inputs and limits that shaped it. You see what the number assumes before you act on it.
We take no advisory commissions and sell nothing. The numbers here have no financial interest in what you decide.
Each tool flags what it cannot account for and when a scenario warrants a professional conversation — not a sales pitch.
Run the numbers on your decision
Every calculator lists its assumptions. Pick the one that matches where you are right now.
