WalletCalcs is written and maintained by Donna KaDell, an independent creative professional and digital publisher.
After years of working independently, managing project-based income, planning around slow seasons, budgeting for business and personal expenses, and looking up financial calculators whenever real-life money questions came up, Donna created WalletCalcs as a practical place to run the numbers.
Why WalletCalcs exists
The goal is simple: make everyday money questions easier to estimate without turning every decision into a spreadsheet project.
WalletCalcs is designed for people who want useful numbers, clear assumptions, and plain-English explanations. As the site has grown, it has become more than a collection of calculators. It is organized around the kinds of financial questions that show up at different stages of life — starting out, working independently, buying a home, building a household, raising a family, planning for retirement, and making sense of the money decisions that happen along the way.
How WalletCalcs is created
WalletCalcs uses a mix of independent research, formula review, manual testing, and AI-assisted drafting and development to create and maintain its calculators and guides. AI tools may help with structure, explanations, and development workflow, but the site is reviewed and maintained with the goal of keeping the tools clear, useful, and consistent.
Donna is not a financial advisor, CPA, or mathematician by trade. WalletCalcs is built from the practical point of view of someone who has had to use financial calculators in real life: to estimate, compare, plan, and make better sense of decisions before taking the next step.
Editorial approach
- Calculators apply standard published formulas where possible and show assumptions in plain language.
- Guide content is written to explain what each input means, what the result can and cannot tell you, and where real-world details may change the outcome.
- Where appropriate, pages reference official or consumer-focused sources such as the CFPB, IRS, FDIC, Department of Labor, Federal Student Aid, and other reliable references.
- Changing figures, such as tax-related limits and contribution rules, are reviewed against primary sources when pages are updated.
- Corrections are made as quickly as an issue can be verified.
What WalletCalcs deliberately avoids
WalletCalcs avoids false precision, one-size-fits-all advice, and calculators that show a number without context. A calculator can clarify a decision, but it cannot see a reader’s full financial life or replace professional advice when the stakes are high.
Important note
WalletCalcs calculators and guides are for general education and planning. They are meant to help users get a clearer picture of the numbers, not replace personalized advice from a qualified financial, tax, legal, or investment professional.
