Each one is a complete business, not a demo. Revenue estimates are conservative and show the math. These are illustrative estimates based on stated assumptions, not guarantees of revenue.

Fintech content sites and mutual fund distributors want interactive calculators on every article, but building and maintaining the math themselves is wasted engineering time. SIPGrow is a drop-in widget — site owners paste one script tag and get a live SIP and compound-interest calculator with yearly breakdown charts, branded to match their site. Sell as a B2B embed subscription.

Revenue Math

40 fintech blogs/distributor sites × $39 = $1,560. There are thousands of personal-finance blogs and independent mutual fund distributor sites that currently link out to third-party calculators instead of embedding their own — this captures that gap.

APlicious Cost
$19 (Starter plan — 40 sites × 12 × 30 = 14,400 calls/mo, just over Starter's typical range but realistic early traffic stays well under 10K)
~12 calculations/day per active site

All 36 endpoints

Six pure-computation calculators with no third-party calls, no data licensing, and no upstream rate limits, plus live crypto, stock, forex, and fundamental-data proxies for apps that need market data.

Starter code — SIPGrow

Two calculators, two calls. Drop this into any fintech blog or distributor site and you have working SIP and compound-interest math with zero backend.
