Purpose and steps
Base loan = price − down payment. The funding fee uses exemption, down-payment tier, and first/subsequent use; financing it adds the fee to principal. Monthly cost includes principal, interest, tax, insurance, and HOA. The calculation runs locally and keeps cash-flow timing consistent with the stated assumptions.
- Confirm currency and monthly versus annual amounts. U.S. tax and loan models should be used within their stated scope.
- Prepare Home price, Down payment, Annual interest rate, Loan term, VA loan use, Funding-fee exemption, Annual property tax, Annual homeowners insurance, Monthly HOA dues, Closing costs, Finance funding fee, Funding-fee override (0 = automatic). Defaults demonstrate the model rather than your personal circumstances.
- Check the headline result and its components. A key interpretation for this tool is: VA-backed purchase loans do not require monthly mortgage insurance.
- Compare the baseline with a changed scenario: A fee exemption or larger down payment can materially change cash-to-close and financed principal.
Input reference and units
These values reproduce the model’s demonstration. Replace them with your own records or measurements; they are not recommended targets.
On a small screen, swipe the table horizontally to see all columns.
| Parameter | Demonstration value | How to enter it |
|---|---|---|
| Home price | 400000 USD | Use dollars and the monthly or annual period stated in the field label; do not enter thousands of dollars. |
| Down payment | 0 % | Check the unit carefully: some tools use a percentage and others a cash amount. |
| Annual interest rate | 6.5 % | Enter a percentage such as 6.5, not 0.065. The equation converts it to a decimal. |
| Loan term | 30 years | Use years here. The model converts to months when the payment schedule requires it. |
| VA loan use | First use | Use the definition shown in the field label; keep this assumption consistent when comparing scenarios. |
| Funding-fee exemption | No | Use the definition shown in the field label; keep this assumption consistent when comparing scenarios. |
| Annual property tax | 4400 USD | Use dollars and the monthly or annual period stated in the field label; do not enter thousands of dollars. |
| Annual homeowners insurance | 1600 USD | Use dollars and the monthly or annual period stated in the field label; do not enter thousands of dollars. |
| Monthly HOA dues | 0 USD | Use dollars and the monthly or annual period stated in the field label; do not enter thousands of dollars. |
| Closing costs | 12000 USD | Use dollars and the monthly or annual period stated in the field label; do not enter thousands of dollars. |
| Finance funding fee | Yes | Use the definition shown in the field label; keep this assumption consistent when comparing scenarios. |
| Funding-fee override (0 = automatic) | 0 % | Enter a percentage such as 6.5, not 0.065. The equation converts it to a decimal. |
Model-specific method
How this calculator produces its result
Base loan = price − down payment. The funding fee uses exemption, down-payment tier, and first/subsequent use; financing it adds the fee to principal. Monthly cost includes principal, interest, tax, insurance, and HOA.
Annuities and the remaining-balance recurrence
A fixed-payment loan is an annuity: the discounted value of all future payments equals the amount borrowed today. Summing that geometric series gives the monthly-payment equation. Match the rate and time unit: monthly payments use an annual nominal rate divided by twelve and a term counted in months.
Each payment is split into interest and principal. Interest uses the opening balance, so paying extra principal now reduces later interest. A zero rate must use P/n rather than the formula’s zero-over-zero form. Keep full precision during the schedule and round only for display; a lender may round each actual posting differently.
P = Σ[t=1…n] M/(1+r)^t M = Pr / (1 − (1+r)^−n) Iₜ = Bₜ₋₁r; Bₜ = Bₜ₋₁ + Iₜ − paymentₜ
- P: principal today
- r: rate per payment period, not the annual percentage
- n: number of payment periods
- M: scheduled payment; B: remaining balance
Worked example
On a $400,000 first-use purchase with no down payment, the 2.15% funding fee is $8,600. Financing it creates a $408,600 loan before other closing costs.

Reading results without overstating them
- VA-backed purchase loans do not require monthly mortgage insurance.
- A fee exemption or larger down payment can materially change cash-to-close and financed principal.
Assumptions and exclusions
- Uses current standard purchase-loan funding-fee tiers and a user override. It does not establish VA eligibility, entitlement, loan limits, appraisal results, lender pricing, seller credits, exemptions, or final closing costs.
