About This Calculator
The New Year's Resolutions Calculator helps you estimate the probability of successfully keeping your resolutions based on real academic research. By entering the number of resolutions you have set, whether you have written them down, and whether you plan to track your progress monthly, the calculator provides a research-backed success rate and a month-by-month projection of how many resolutions you are likely to maintain.
The calculator is based on peer-reviewed studies including a University of Bristol study of 3,000 participants by Richard Wiseman (2007) which found that 88% of New Year's resolutions fail, and research by Norcross and Vangarelli (1988) tracking resolution success over time. The model accounts for key success factors: writing down goals increases success by 42%, and monthly progress tracking improves outcomes by an additional 33%. Successful goal setting follows the SMART framework — specific, measurable, achievable, relevant, and time-bound goals consistently outperform vague intentions.
Regional Notes: New Year's resolutions are a global tradition observed across IN, US, and UK. The research data powering this calculator comes from international studies — the University of Bristol (UK), the University of Wisconsin (US), and global participant surveys. The behavioral principles of goal setting, progress tracking, and written commitment apply universally regardless of region or culture.
Frequently Asked Questions
How does the New Year's Resolutions Calculator work?
Enter the number of resolutions you have set, whether you have written them down, and whether you plan to track progress monthly. The calculator uses research-backed statistics from University of Bristol and clinical psychology studies to estimate your success probability at 1, 3, 6, and 12 months.
What percentage of New Year's resolutions fail?
According to a 2007 University of Bristol study of 3,000 people led by Richard Wiseman, 88% of New Year's resolutions fail. However, people who write down their goals are 42% more likely to succeed, and those who track progress monthly see even higher success rates.
Does writing down resolutions really help?
Yes, research consistently shows that writing down resolutions increases the likelihood of success by approximately 42%. Written goals are more concrete, serve as a constant reminder, and create a stronger psychological commitment to follow through.
How does tracking progress affect resolution success?
A 2014 study found that 33% of people who failed their New Year's resolutions admitted they did not keep track of their progress. Monthly progress tracking helps maintain focus, allows for course correction, and reinforces positive habits throughout the year.
How many resolutions should I set?
Research suggests that setting fewer, more focused resolutions leads to higher success rates. Each additional resolution dilutes your focus and reduces per-resolution success probability. Most experts recommend 1 to 3 specific, measurable resolutions.
What is the best way to set effective New Year's resolutions?
Use SMART goals: Specific, Measurable, Achievable, Relevant, and Time-bound. Approach-oriented goals (starting a new habit) tend to succeed more than avoidance-oriented ones (stopping a habit). Set monthly milestones and track your progress in a journal or app.
How long do most people keep their New Year's resolutions?
Research shows about 64% of people maintain their resolutions through the first month, 46% through three months, 30% through six months, and only about 12% keep them for the full year. The steepest decline happens in the first few weeks.
