What BAC pays per dollar (the "compra") when the CDP matures. The small notch is where your trend points. You can also drag on the chart or use the arrow keys.

Assumptions

BAC compra today₡

BAC buys dollars at ₡450 and sells at ₡464. Converting is one-way: buying the dollars back later costs that ₡14 gap, about 3%.

CDP yield, after tax%

A placeholder. Use the net annual rate on the CDP statement, since interest is taxed at source.

Cash yield%

What the $5,000 earns per year sitting in the account.

Dollar trend

Keeps fallingRecovers

How fast you expect the dollar to move against the colón, per year. A guess, not a forecast. It moves the risk cone and the odds.

Volatility

CalmJumpy

How much the rate bounces around the trend. Higher widens the cone.

An extra payment should

Shorten the loan Lower the cuota

Tell BAC which one you want when you pay, and ask whether they charge a fee. Shortening saves more interest.

Timing is rounded: "now" means before the October 4 payment, "December" means right after the December payment.
