Frequently Asked Questions

How should couples split debt payments fairly?
A common method is proportional splitting based on income. If one partner earns 60% of the household income, they contribute 60% of the total monthly debt payment. This calculator uses this proportional model to ensure both partners contribute a fair share according to their means.
What is the difference between debt snowball and debt avalanche?
The Debt Snowball strategy focuses on paying off the smallest balance first, giving you quick psychological wins. The Debt Avalanche strategy targets the debt with the highest interest rate (APR) first, which mathematically saves you the most money in interest over time.
Does the calculator combine both partners' debts?
Yes. You enter all household debts into a single list. The calculation engine combines these debts and treats them as a shared responsibility, calculating a single unified payoff timeline and total interest cost.
How is each partner's contribution calculated?
The tool takes each partner's monthly take-home income and calculates their percentage of the total household income. It then applies this percentage to the total required monthly debt payment to determine a fair monthly contribution for each person.
Does paying more each month reduce interest?
Yes. Any extra payment entered into the calculator is applied directly to the principal balance of the targeted debt. Paying down the principal faster directly reduces the amount of interest that accrues over the lifetime of the loan.
