Our authors & reviewers
Every guide and calculator explainer on Calcavio is written and reviewed by named people with real experience in personal finance, lending and tax.
Daniel breaks down income tax, take-home pay, budgeting, and saving without the jargon. After years preparing returns and writing about household money, he's fluent in brackets, deductions, and the difference between marginal and effective rates. He pins every tax figure to the current IRS year and flags exactly what changes from one filing season to the next, so readers aren't caught out by stale numbers.
Arjun turns math, physics, and chemistry calculators into clear explanations anyone can follow. With a physics PhD and years teaching undergraduates, he's good at the part textbooks skip: why a formula works and where learners trip up. His education tools - GPA, grade, and study planners - get the same step-by-step treatment, with worked examples instead of hand-waving.
Hannah reviews and writes Calcavio's health tools - BMI, calorie, hydration, BMR, and pregnancy-timeline calculators for medical accuracy. Her role is to keep the content evidence-based, conservative, and clearly framed as education, never diagnosis. Every health result is a starting estimate, and she makes sure each tool tells readers plainly when to consult a qualified healthcare professional.
Kenji writes Calcavio's tech tools and explainers - data storage, bandwidth, screen and file-size math, and the everyday computing questions that quietly trip people up. A former software engineer, he's fluent in the units and edge cases, and he keeps explanations grounded for readers who just want the right number fast, without a comp-sci lecture attached.
Marcus writes about the money side of running a business - margins, break even, cash flow, markup, and financing. He's built and run small companies himself and holds an MBA, so his tone is practical rather than theoretical: the numbers a founder needs to make a call this quarter, shown clearly with the working. He's blunt about the costs first-time owners underestimate.
Nathan spent more than a decade on the lending side - first as a mortgage loan officer, later helping borrowers untangle auto and personal loans. He writes about monthly payments, APR, refinancing, and debt payoff in plain English, translating the fine print lenders gloss over. His focus is simple: show the true cost of borrowing before you sign, not after.
Olivia covers Calcavio's sports and lifestyle calculators - pace, VO2 max, calorie burn, one-rep max, and the fun everyday tools in between. A certified running coach with a sports-science background, she writes for real training questions: what the number means, how to actually use it, and when to trust your body over the math.
Priya covers investing and retirement for Calcavio - compound growth, fees, ROI, 401(k)s, Roth conversions, and the 4% rule. With a finance master's and nearly a decade writing about markets, she's careful about one thing above all: realistic projections and honest risk. She'll never promise a return no one can guarantee, and she shows how fees quietly erode a portfolio over time.
Sofia writes about life, term, disability, and health-related coverage - how much you actually need and what you're really paying for. A former licensed agent, she's watched policies get oversold, so her guides stay buyer-first: estimate your true need, understand the trade-offs, and skip the coverage that doesn't earn its premium. Clear math over sales pressure, every time.
