Frequently asked questions
Is SIP Calculator free?
Yes — completely free, with no signup and no watermarks. PL Tools is supported by a small number of non-intrusive ads.
Is anything I type sent anywhere?
No. Every calculation runs in your browser; nothing is uploaded or stored.
How precise are the results?
Standard double-precision arithmetic (about 15 significant digits), shown rounded. Finance results are estimates from the formula stated on screen — lenders and funds may round or charge differently.
Is the SIP result guaranteed?
No. It assumes the same return every year and payments at the start of each month. Real markets go up and down, so treat it as an illustration, not a promise or investment advice.
Does it work on my phone?
Yes. PL Tools works in any modern browser on iPhone, Android, tablets and desktop — there's nothing to install.
