Frequently Asked Questions
Everything you need to know about FinCalcHub Marketing tools
Is FinCalcHub free to use?
Yes! All 10 calculators are 100% free. No registration, no subscription, no hidden fees. Use as many times as you want.
Is my financial data safe?
Absolutely. All calculations run 100% in your browser. Your inputs (loan amounts, salary, crypto amounts) are never sent to any server. The only external request is to CoinGecko's API for live crypto prices — and that only sends the currency code (like "pkr"), not your financial data.
How accurate are the crypto prices?
We fetch real-time prices from CoinGecko's public API every 30 seconds. However, these are indicative rates and may differ slightly from exchange prices due to market volatility. Always verify on your exchange before trading. If the API is unavailable, we show cached/fallback rates.
Which currencies are supported?
We support 8 currencies: USD ($), EUR (€), GBP (£), PKR (Rs), INR (₹), AED (د.إ), CAD ($), and AUD ($). The global currency selector in the header updates all calculators at once.
Can I use this on my phone?
Yes! FinCalcHub is fully responsive and works perfectly on mobile phones, tablets, and desktops. You can even install it as a Progressive Web App (PWA) on your home screen for instant access — just use your browser's "Add to Home Screen" option.
Are the tax calculations accurate for Pakistan?
Our tax calculator uses FBR tax slabs for tax year 2025-2026. It provides a good estimate for salaried individuals and business owners. However, actual tax may differ based on deductions, tax credits, special zones, and other factors. Always consult a tax professional for filing.
What is the difference between margin and markup?
Margin = Profit ÷ Selling Price × 100 (profit as % of revenue). Markup = Profit ÷ Cost Price × 100 (profit as % of cost). Example: If cost is Rs 1,000 and you sell for Rs 1,500, profit is Rs 500. Margin = 33.3%, Markup = 50%. Our Profit Margin calculator shows both.
What is a good LTV:CAC ratio for SaaS?
A healthy SaaS business should have LTV:CAC ≥ 3:1. This means each customer generates 3x more value than it costs to acquire them. A ratio below 1:1 means you're losing money on each customer. The ideal payback period is under 12 months. Use our SaaS CAC & LTV tool to check your metrics.
How do I calculate my freelance hourly rate?
Add your desired income + business expenses, divide by (1 - tax rate) to get gross revenue needed, then divide by your annual billable hours. Our Freelancer Hourly Rate Calculator does all this automatically, also accounting for vacation days and desired profit margin. Most freelancers undercharge because they forget non-billable time!
Do I need to create an account?
No! FinCalcHub requires zero registration. Just open the site and start calculating. Your currency preference is saved locally in your browser for convenience.
