About Us
Our Mission
CDCalculator provides free, accurate financial calculators with clear formulas and charts. We focus on certificates of deposit, mortgages, retirement, and everyday money decisions.
Independent & Free
Every tool runs in your browser. No sign-up required. We publish guides on our blogs to help you interpret the numbers responsibly.
Editorial Team
Our writers and developers research standard financial formulas used by banks and planners, then build tools that are fast, accessible, and easy to use.

What We Offer
CDCalculator launched in 2026 with a full directory of 70+ financial calculators plus in-depth blog articles. Whether you are comparing CD rates, estimating a mortgage payment, or planning retirement contributions, our calculators give you instant results with charts and schedules.
Our calculators cover
- Certificates of deposit — growth projections, tax-adjusted returns, and accumulation schedules.
- Mortgages & real estate — monthly payments, affordability, refinancing, and rent vs. buy analysis.
- Retirement planning — 401(k), IRA, pension, Social Security, and annuity projections.
- Loans & debt — payoff timelines, consolidation scenarios, and interest comparisons.
How We Build Our Tools
Each calculator uses widely accepted financial formulas. We document the math on every calculator page so you can verify results against a spreadsheet or your bank statement. Charts and schedules are generated in your browser using Chart.js — no data is sent to our servers.
Our editorial team pairs calculators with long-form guides on the Blogs section, updated for the 2026 planning year.
Who We Serve
CDCalculator is built for savers, homebuyers, retirees, and anyone who wants quick, transparent numbers before talking to a bank or advisor. We do not sell financial products, accept paid placements, or require user accounts.
