Controlled inputs
Each study states what changes and what stays fixed so the tradeoff is visible.
ASK LINC RESEARCH
Financial questions are more usefulwhen you can inspect the evidence.
These are controlled studies produced with Ask Linc’s deterministic financial models. We publish the inputs, calculations, historical coverage, limitations, and the result—not just the conclusion.

01 / RETIREMENT · 685 HISTORICAL TESTS
What changed the outcome?
One fictional household, three scenarios. We changed retirement age or spending and reran the plan across 685 overlapping historical market sequences.
KEY RESULT620/685 histories lasted at 55 with $84k spending; 685/685 lasted after either of two controlled changes.

Same household, spending, Social Security, allocation, and life expectancy. Only the retirement date changes.
KEY RESULTTwo more working years added roughly $252k at retirement in this example and moved the tested result from 620/685 to 685/685.
Read the study →03 / SEQUENCE RISK · 685 HISTORICAL TESTSHow much does the order of returns matter?
The plan is identical in every test. Only the historical market sequence changes—enough to produce both surviving and depleted outcomes.
KEY RESULTThe same age-55 plan survived 620 histories and ran short in 65, showing why an average return can hide retirement risk.
Read the study →04 / COAST FIRE · CONTRIBUTION TRADEOFFWhat if you nearly stop saving?
We cut annual contributions from $45,000 to $5,000 for the same fictional household and held retirement age and spending constant.
KEY RESULTBoth plans survived all 637 tested histories, but the lower-saving path reached retirement with about $541k less modeled capital.

Designed to be checked, not merely believed.
Deterministic calculations
The financial engine produces the numbers. The language model explains them; it does not invent them.
Historical context
Where historical testing is used, we disclose the date range, window construction, and why overlapping histories are not probabilities.
Limits in plain English
Every study names what the test cannot establish, including assumptions that could materially change the result.
