☕ Love Our Free Calculators? Help Keep Them Running.

Welcome to Niche Calculators. My goal is simple: to provide accurate, niche calculators without forcing you to sign up or pay a cent. Whether you need to calculate concrete volume or loan repayments, the tool is right there, free to use.

However, creating these complex tools isn't completely free. I rely on the support of visitors like you to keep the lights on.

🪙 The "Crypto" Dilemma

You might be wondering, "Why can't I just send money via PayPal or a credit card?"

Unfortunately, the financial world has borders that don't work in my favour. As a creator based in Zimbabwe, I am locked out of every major payment processor (PayPal, Stripe, etc.). These companies do not support my region.

⛓️ This is why I have to ask for support via Cryptocurrency. Digital currency is borderless. It is the only tool that allows me to accept your generosity despite the banking restrictions imposed on Zimbabwe. If you do not have crypto but you still want to help you can use Ecocash (mobile money platform) check under the QR code for information.
