Money Date Planner
Couple's financial snapshot with surplus analysis, debt ratio, emergency fund status, and goal timeline.
About this calculator
This calculator gives couples a quick joint financial snapshot from five shared numbers. Monthly surplus is simply combined income minus combined expenses, annualized for the year-end view. Emergency fund status compares your combined savings against a three-month-expenses target, capped at 100% once you've hit it. Months to your next financial goal divides the remaining amount needed (goal minus current savings) by your monthly surplus — if there's no surplus, it reports zero rather than a negative or infinite timeline.
The debt-to-income figure here is calculated as total outstanding debt divided by combined annual income, which measures overall debt load relative to earnings rather than the monthly-payment-based DTI ratio lenders quote — worth knowing so you don't confuse the two if you've seen DTI calculated elsewhere. A financial alignment score (0-100) starts at a baseline of 50 and adds points for having a positive surplus, keeping that debt load under 36% of annual income, being fully funded on the emergency fund, and saving at least 20% of income — a simple additive rule of thumb rather than a validated couples'-finance metric. Finally, the calculator recommends a monthly budget split using the well-known 50/30/20 rule: 50% of combined income to needs, 30% to wants, and 20% to savings, regardless of what you're actually spending. None of this replaces a real conversation about individual financial histories, debt interest rates, or differing risk tolerances between partners — it's designed as a conversation-starting scorecard for a recurring "money date," not a comprehensive financial plan.

Frequently Asked Questions
How is the debt-to-income ratio calculated here, and is it the same as what mortgage lenders use?
This calculator computes DTI as total outstanding debt balance divided by combined annual income — a measure of overall debt load relative to yearly earnings. That's different from the DTI ratio lenders typically quote, which compares your monthly debt payments to your monthly income, so don't assume the two percentages are directly comparable.
How does the calculator determine "months to financial goal"?
It subtracts your current total savings from your goal amount, then divides that remaining gap by your monthly surplus (combined income minus combined expenses). If your monthly surplus is zero or negative, it reports 0 months rather than an infinite or negative timeline, since there's no surplus accumulating toward the goal under your current numbers.
What goes into the financial alignment score?
It starts at a baseline of 50 points and adds 15 for having a positive monthly surplus, 10 for keeping debt under 36% of annual income, 15 for a fully-funded (100%+) emergency fund, and 10 more for a surplus that's at least 20% of combined income, capped at 100. It's an additive rule of thumb the calculator uses to summarize your numbers, not a validated couples'-finance metric.
Does the recommended 50/30/20 budget reflect what we're actually spending?
No — the needs/wants/savings amounts shown are simply 50%, 30%, and 20% of your combined income applied to the standard 50/30/20 budgeting rule, regardless of your actual expense categories or spending habits. It's a suggested target allocation to structure your money-date conversation around, not a recalculation of your current budget.
