When to use SmartAsset
SmartAsset is handy for a quick, friendly ballpark and if you actually want to be connected with a financial advisor — that’s the service it’s built around. Its calculators are clean and require little input.
When to use Coastline
Choose Coastline when you want to go deeper than a ballpark without handing over your contact info: real tax modeling in both your working and retirement years, strategy comparisons (Roth conversions, withdrawal order, Social Security timing), market stress-testing, and a transparent breakdown of how every number was computed. Nothing is sold to you.
Both tools are free. This comparison is written by Coastline, so weigh it accordingly — try both and use whichever answers your question. SmartAsset is a well-regarded tool; the differences below are about focus, not quality.
Common questions
Is the SmartAsset retirement calculator free?
Yes, it’s free to use, though it’s designed to match you with financial advisors and may ask for contact information. Coastline is free with no signup and no advisor referral.
Which is more detailed?
Coastline models more of the plan — full federal/state tax math, Roth-conversion and withdrawal-order strategy, Social Security timing, and market stress-testing — and shows the calculation behind each figure. SmartAsset favors speed and simplicity.
Does Coastline sell my information?
No. Coastline has no accounts, no database, and doesn’t match you with advisors. Your inputs are used to run the projection and then discarded.
