Cheapest Way to Test a Whole Family: A Strategic 2026 Guide
Multi-kit discounts, oldest-generation-first strategy, and the free-upload trick that lets one kit reach multiple matching databases.
Testing one person is straightforward. Testing a whole family of six to twelve people without spending thousands takes some strategy. Here is the cheapest sensible approach as of early 2026.
Test the oldest generation first, always
This is the most important rule. Your grandmother’s DNA is closer to her ancestors than yours is. She has roughly 1,400 to 1,800 centimorgans of detectable shared DNA with her second cousins, where you might have 100 to 200. Her DNA also has matches you literally cannot have, because some segments she inherited did not pass down to you.
If a relative is elderly, ill, or simply older than the other candidates, test them first. DNA is unrecoverable once a person dies. Order their kit the same week you make the family-testing decision, before anything else.
Use multi-kit discounts during peak sale windows
Several brands offer multi-kit discounts during major sale events. DNA Day (April 25), Mother’s Day, Father’s Day, Prime Day in July, Black Friday and Christmas are the deepest windows.
Rough indicative pricing as of early 2026:
- AncestryDNA sale: $39 per kit, sometimes $29 for two-kit bundles during peak windows.
- MyHeritage DNA sale: $39 per kit with similar multi-kit treatment.
- FamilyTreeDNA Family Finder sale: $59 per kit, occasional multi-kit pricing.
- Living DNA sale: $79 per kit.
Do not buy at full sticker price for a family-testing project. Wait for a sale window. The savings on six kits at $60 off each is $360.
Upload instead of buying duplicates
This is where the real money is saved. After one person tests on AncestryDNA, you have a raw DNA file. That file can be uploaded free to MyHeritage, FamilyTreeDNA and Living DNA, putting the same person in four matching databases for one kit price.
For a family-testing project, that means: each unique tester gets one kit from the brand with the largest database (AncestryDNA), and that one kit’s raw data goes into the other three databases free. You do not buy four kits per person. You buy one and upload three times.
Our upload guide and free upload sites guide cover the mechanics.
Cost-per-person math, worked
A six-person family testing project, done well:
- 6 AncestryDNA kits at $39 sale = $234.
- Add roughly $50 shipping across the orders = $284 total.
- All six uploaded free to MyHeritage, FamilyTreeDNA and Living DNA = no additional cost.
Result: six people in four major matching databases for about $284, or roughly $47 per person to reach four databases.
The naive approach (buying six AncestryDNA kits, six MyHeritage kits, six FamilyTreeDNA kits, six Living DNA kits at full price) runs over $2,000 for the same coverage.
When to splurge instead
Two reasons to spend more.
Y-DNA testing for surname research. If you have a paternal-line question (a brick wall on a specific surname, or a suspected non-paternity event to investigate), pay for FamilyTreeDNA’s Big Y-700 for one male line carrier. You do not need to test every male relative; one well-chosen tester answers most questions.
