About the Will It Last? Predictor
Will It Last? turns two names into a long-term score between 40% and 100% and a playful number of years. Both numbers come from the same name-based seed, so a pair always gets the same forecast. It suits anniversaries and gentle teasing between couples who know it is a game. It does not know how long you have been together, how you treat each other or what you are building, which are the things that decide how long a relationship lasts.

What Long-Lasting Couples Tend to Have in Common
Research on newlywed couples by John Gottman's team (Driver & Gottman, 2004) found that small everyday moments of attention, such as responding when a partner points something out, played a real part in how well couples handled conflict later. None of that can be read from a name.
If you want a better forecast than this tool can give, ask each other one question this week: "What is one small thing I do that makes you feel cared for?" Then do more of it.
Treat the number of years as a playful milestone, not a countdown. Some couples save a screenshot on their anniversary and open it again a year later. The forecast will not have moved, because your names have not, which is a gentle reminder that everything that really changed in that year came from what the two of you did together.
How the Result Is Calculated
- What it uses
- The letters of both names.
- The exact method
- Only the letters of both names are kept (lower-cased, in the order typed), and their CRC32 checksum is used as a fixed "seed" number. Score = 40 + (seed mod 61), so 40-100%. "Predicted years" = 1 + (seed mod 50).
- Example you can reproduce
- "Rahul" + "Priya" always gives 59%.
- What it can't tell you
- No calculator can predict how long a relationship lasts.
