TL;DR

The 90% Rule is a budgeting guideline suggesting homeowners should plan to spend about 90% of their estimated project budget to avoid overspending. Experts say it can save thousands on home renovations. This approach is gaining popularity among DIY enthusiasts and contractors alike.

The 90% Rule is emerging as a practical strategy for homeowners to control renovation costs, with proponents claiming it can save thousands of dollars on home projects. This rule advises planning to spend about 90% of your initial estimate, leaving a buffer for unexpected expenses. While it is gaining popularity among DIYers and contractors, its effectiveness is based on anecdotal evidence and expert advice, not formal studies.

The 90% Rule was first promoted by home improvement consultants and financial advisors as a way to prevent budget overruns. According to industry experts, the rule encourages homeowners to set aside a reserve of approximately 10% of their estimated costs, which can be used to cover unforeseen expenses or adjustments during the project. Advocates say this approach can help avoid the common pitfall of underestimating costs, which often leads to project delays or incomplete work.

Early reports from homeowners and contractors who have adopted the rule indicate that it can lead to substantial savings. For example, a DIY homeowner in Florida reported saving over $5,000 on a kitchen remodel by adhering to the 90% guideline and adjusting their budget accordingly. Experts also note that this method promotes more realistic planning and reduces financial stress during renovation projects.

However, critics caution that the rule is not a formal financial or construction standard. It relies heavily on accurate initial estimates and disciplined budgeting, which can vary widely among individuals. The rule’s success depends on careful planning and honest assessment of project costs, which may be challenging for first-time renovators.

Origins and Growing Adoption of the 90% Budgeting Guideline

The concept of setting aside a reserve for home projects has been around informally for years, but the specific 90% Rule gained traction in early 2024 through social media and home improvement forums. It is promoted by financial advisors, DIY influencers, and some contractors as a simple yet effective way to manage project costs. The idea is rooted in the common experience that many homeowners underestimate expenses, leading to budget shortfalls and incomplete projects.

While the rule is not officially endorsed by any industry body, its principles align with established financial planning strategies that emphasize contingency funds. The rule’s popularity has grown as more homeowners seek cost-effective ways to handle rising renovation costs amid economic uncertainty.
