I built a free U.S. finance calculator website for paycheck, tax, mortgage and retirement estimates

Hi everyone,

I recently built FinanceCalcHub, a free U.S. financial calculator website designed to help people quickly estimate common personal finance numbers.

The goal is simple: many people make decisions based on gross income, but the real question is usually what they actually keep, what a payment really costs, or how money could grow over time.

FinanceCalcHub currently includes calculators for:

- Paycheck / take-home pay estimates

- Federal tax estimates

- Salary calculations

- State paycheck estimates

- Mortgage payments

- Mortgage affordability

- Loan payments

- Debt payoff

- Credit card payoff

- Savings growth

- Compound interest

- 401(k) estimates

- Retirement planning

Website:

A few direct tools:

Paycheck Calculator:

Federal Tax Calculator:

Mortgage Affordability Calculator:

https://www.financecalchub.com/calculators/mortgage-affordability

401(k) Calculator:

https://www.financecalchub.com/calculators/401k

The calculators are educational estimates only, not professional financial or tax advice, but the goal is to make basic financial math easier to understand for everyday users.

I’d appreciate any feedback on:

1. Which calculator is most useful?

2. What calculator should be added next?

3. Is the site clear enough for beginners?

4. What would make it more trustworthy or useful?

Thanks in advance for any feedback.
