Compare costs on the same basis
A lower pack price does not always mean a lower price per unit. Use the same currency and measurement unit for each option, then compare the unit costs. When sharing a purchase, choose equal shares, percentages or relative weights to match the agreement.
Savings and loan tools use the assumptions described on their own pages. Interest rate and APR are different measures: APR can include charges as well as interest. Check which rate a tool requires and compare its estimate with the provider's actual terms.

Share a gift between two people

Common questions
How do I compare two different pack sizes?
Use Sale Item Per Unit Cost for each pack, entering the price and quantity in the same units. Compare the resulting cost per unit; include delivery or other charges separately if relevant.
Can I split a bill unequally?
Yes. Use a weighted split when shares have relative weights, a percentage-share tool for a stated percentage, or an equal-split tool when everyone pays the same amount. Agree the allocation before using the result.
