Purchase cash target and savings trajectory
Purchase cash target and savings trajectoryThe rising purchase-price target feeds a stacked down-payment, closing-cost, and emergency-reserve goal while the savings curve shows whether current contributions intercept that target by the planned month.

Calculator guide
Understanding Home Down Payment Savings Planner Calculator
A purchase cash goal is larger than the down payment alone. This planner projects the home price to the purchase date, then separately reserves down payment, closing costs, and cash that should remain after closing.
Detailed calculation process
Detailed purchase cash and savings calculation
The default case projects a $420,000 target home over 36 months.
General formula: H_f=H_0(1+g)^(m/12)T=H_f(d+c)+RS_f=FV(S_0,i,m,q)G=max(T-S_f,0) The future home price establishes percentage-based cash needs; the savings account is projected independently to the same month.
What each symbol means
Worked substitution with the default inputs
Projected savings plus the displayed gap equals the $120,557.43 target whenever a shortfall remains.
Worked situations
Practical examples
- A $420,000 home growing 3% for three years reaches about $458,946 before the down-payment percentage is applied.
- A 20% down payment, 3% closing reserve, and $15,000 emergency reserve create a target materially above 20% of today's price.
Better inputs
Useful tips
- Keep emergency funds separate from money expected to be spent at closing.
- Use a conservative savings yield for short purchase horizons.
- Refresh property-price and closing-cost assumptions with local evidence.
Before relying on the result
Limitations and common mistakes
- The page does not model mortgage approval, appraisal, seller concessions, or specific closing quotes.
- Home-price growth and savings yield are uncertain.
- Taxes, insurance, moving, repairs, and furnishing costs may require separate reserves.
Reference
Key terms

Important note
Confirm actual loan-program, closing, and reserve requirements before committing to a purchase date.
Frequently asked questions
Why not use today's home price?
The purchase is planned for a future date and the entered growth assumption changes the price basis.
Is a 20% down payment required?
No. Loan programs differ; enter the percentage relevant to the intended plan.
Does the required contribution guarantee the purchase?
No. It solves the entered cash target and return assumptions only.
