WordPress Interest & Loan Calculators

I need a small suite of six financial calculators that I can drop straight into a WordPress site. Each tool must share the same simple, functional styling so they sit naturally inside a clean theme—no flashy gradients or animations, just clear fields, instant results and mobile-friendly layout. What I’m after • Clean, commented HTML + CSS + JavaScript (or a lightweight React/Vue component if you prefer) wrapped so I can embed with a shortcode or Gutenberg block. • One self-contained file/folder per calculator; I don’t want a bulky plug-in that bundles them all together unless it stays under the normal WP size limits. • All calculators accept the full set of fields: principal amount, interest rate, time period, additional contributions and any extra-payment details. Labels and placeholders must be easy for me to localise later. • No need to remember user inputs between sessions; every refresh starts clean. • Calculations must be accurate to at least two decimal places and run client-side so there’s zero server load. • Please keep the output tables responsive and copy-friendly. Deliverables 1. Compound Interest Calculator 2. Simple Interest Calculator 3. Daily Compound Interest Calculator 4. Loan Calculator with Extra Payments 5. Loan Payoff Calculator 6. Amortization Calculator with Extra Payments Acceptance I’ll drop each calculator into a test page; if it renders correctly, produces the expected numbers for sample scenarios I provide and passes a quick Lighthouse performance check, I’ll sign the milestone straight away.
