Description by Gang Chen Written by the developer, not by AppBrain. Click to read.
Every calculator is built for real decisions: enter your numbers, see the answer instantly, and get the supporting detail — charts, breakdowns, and full amortization tables — right underneath.
BUILT FOR THE US AND CANADA
Most calculators guess at your country. CalcKit asks once and then gets it right:
• Take-home pay with federal and state or provincial brackets
• Sales tax that knows GST, HST, and PST — not just a flat rate
• Retirement savings modeled as 401(k)/IRA or RRSP/TFSA
• Closing costs including land transfer tax
• Imperial or metric units, set to match your region

PRIVATE BY DESIGN
CalcKit works entirely offline. There is no account, no sign-up, and no server — your salary, your mortgage, and your health numbers stay on your device and are never uploaded anywhere.
CALCKIT PRO
A single one-time purchase — no subscription:
• Remove banner ads
• Extended history: 100 calculations instead of 20
• Unlimited saved calculations instead of 5
Note: the currency converter uses built-in offline reference rates for eight major currencies and is intended for quick estimates, not for trading or settlement.
