Accuracy Policy
What our results mean—and what they do not mean.
Estimates, not guarantees
Results depend on the values entered, the formula implemented, rounding, and stated assumptions. They are intended for education and planning.
Validation
Tools check many invalid inputs, but they cannot identify every unrealistic or unsuitable scenario.
Independent verification
Verify consequential results with official documents, your provider, or a qualified professional before acting.
