A closer look at HouseRuler
HouseRuler is a free 7th house ruler calculator for people learning relationship astrology, with written interpretations for each house placement and a paid personalised report.
One placement, worked out for you
You're reading up on relationship astrology and the phrase 7th house ruler keeps coming up, usually with the assumption that you already know yours. In a birth chart, the 7th house is the one astrologers tie to committed partnerships and marriage. Its ruler is the planet that rules whichever zodiac sign sits on the cusp of that house.
HouseRuler does that lookup for you. You enter a birth city, date, time and time zone and press Calculate. The page shows the rule it applies, listing the planet for each sign, such as Mars for Aries and Venus for Taurus, which is a nice touch if you're learning. There are also twelve interpretation pages, one for the ruler landing in each house.
The form asks for the hour and minute of birth, so you'll need a birth time to use it. And this is astrology, so read the results as interpretation and not as evidence about your relationships.
Free to calculate, with a report for sale
The calculator is free. HouseRuler also sells a one-time report called the Love & Marriage Blueprint, which it says covers partner patterns, 12-month relationship themes and a 30-day action plan.
On November 11, 2026 the page showed US$9.90, marked down from US$29.90 as a limited-time offer, with no subscription. The report is delivered after checkout, and a restore link goes to your payment email.
A word about your birth details
The privacy policy, last updated March 9, 2026, draws a line between the free and paid sides. For free calculations, it says birth input is processed locally in your browser. For a paid report, the site stores your purchase email, payment identifiers from Creem or PayPal, your birth input and a snapshot of the generated report, so it can deliver and restore it.
The policy names Replicate as the service used to generate the personalised report, Resend for the emails and Google AdSense for ads. It gives no fixed retention period, saying paid-order data is kept only as long as needed. No person or company is named, and the contact is a support email.
If you're learning relationship astrology and have your birth time handy, the free calculator is an easy first stop.
